▼ This dissertation develops a systematic and comprehensive approach to management of uncertainty by accomplishing four major objectives: address model uncertainty for the permanent deformation model, develop a method to reduce computational expense, design a framework for incorporation of uncertainty in pavement design, and demonstrate a framework for risk-based mechanistic-empirical (M-E) pavement design. Pavement analysis is impacted by uncertainty from a number of significant sources such as field variables, uncertainty in the predicted behavior models, and errors in these models. These sources of uncertainty are not currently accounted for in the pavement design process in an efficient and comprehensive way. Management of uncertainty for M-E pavement design requires quantification of model uncertainty and the permanent deformation model is significantly susceptible to model uncertainty. A thorough calibration process is performed in this dissertation on three prevalent permanent deformation models: a model incorporating shear theory, an axial strain model, and a model combining both mechanistic theories. Understanding the uncertainty associated with these permanent deformation models is necessary to accurately predict pavement performance, but current models are computationally expensive. A surrogate model is constructed that accurately emulates the M-E flexible pavement design equations. The third major objective develops a logical and efficient process for incorporating uncertainty into M-E pavement design. Propagation of uncertainty from input variability, M-E prediction models, and the surrogate model is demonstrated and a sensitivity analysis is performed. Analysis of methods for the selection of the quantity and location of training points for the surrogate model is presented. Reliability analysis is performed utilizing probabilistic and analytical methods. A method for developing load and resistance factors is presented as a practice-ready option for reliable pavement design. The final major objective presents a framework for risk-based design in the context of mechanistic-empirical pavement design. Through these four major objectives, this dissertation presents a comprehensive framework for management of uncertainty in flexible pavement design. Advisors/Committee Members: P.K.

▼ Unbound granular materials (UGMs) constitute the supporting layer of flexible pavements. The performance of unbound granular base layer has been widely recognized to be influenced by its resilient modulus and permanent deformation, as well as whether it is reinforced by geogrids. The UGMs are found to exhibit moisture-sensitive and stress-dependent nonlinear cross-anisotropic behaviors, but are not adequately characterized by existing models in pavement engineering. The primary objective of this study is to develop a comprehensive methodology to accurately characterize the constitutive behavior of UGM, and predicting the performance of UGM in flexible pavements. Furthermore, this study aims at quantifying the influence of geogrid on pavement performance to facilitate the incorporation of geogrid into Pavement ME Design Software. A new resilient modulus model is first developed to characterize the moisture-sensitive and stress-dependent nonlinear cross-anisotropic behavior for UGM. The moisture dependence of UGM is characterized by the degree of saturation and the matric suction. This model is validated by the laboratory resilient modulus tests on the selected UGMs at different moisture contents. The finite element approach is then employed to predict the performance of flexible pavements by incorporating this constitutive model for UGM. To accurately predict the rutting depth of base course, a new mechanistic-empirical rutting model is also developed to forecast the rutting behavior of UGM at different stress levels. In this study, the repeated load triaxial tests are performed on a variety of granular materials to determine the resilient modulus and permanent deformation properties. The measured resilient modulus and permanent deformation properties are statistically related to a wide variety of performance-related base course properties. These regression models can accurately and efficiently predict the resilient modulus and permanent deformation properties of UGM. A laboratory methodology is developed to evaluate the impact of geogrid on cross-anisotropy and permanent deformation properties of UGM. This impact is successfully predicted by an analytical model. Finite element models are developed to simulate the geogrid-reinforced structures by considering the geogrid-reinforcement mechanisms. These numerical models are validated by the large-scale tank tests. The validated finite element models provide a sound basis for predicting the performance of geogrid-reinforced pavements.

▼ Stochastic analysis provides a rationale for the treatment of uncertainties, founded on the principles of probability theory and statistics, and is concerned with a quantifiable measure of the confidence or the reliability associated with any design process. In this thesis, a stochastic approach is employed in the design of flexible pavement structures, to facilitate the development of safe and reliable pavement structures. The important aspects that have been explored in sufficient detail include the system reliability and global sensitivity analysis, and the spatial and temporal uncertainties that pervade the life of pavements. Chapter 1 of the thesis provides an introduction to the stochastic modelling of flexible pavements and its significance in the present day. Highlighting the need for this study, this chapter also enumerates its objectives and presents an overview of the organization of the thesis. Chapter 2 provides a review of the existing literature of the design of flexible pavements and the approaches adopted to deal with the various sources of uncertainties in a probabilistic setting. The estimation of the uncertainties in fundamental pavement design inputs and their integration into the general performance prediction procedures has become a required component of the modern Mechanistic-Empirical pavement design methodology, which has been described in detail. This chapter also provides the scope of the thesis by identifying the areas of stochastic analysis that have received little attention in the flexible pavement design, which include the effect of spatial variability on the pavement structural responses and the techniques of global sensitivity analysis. Chapter 3 provides a detailed overview of the various methodologies adopted in this thesis to carry out the stochastic modelling of flexible pavements. The fundamental technique adopted for the analysis of reliability is the Monte Carlo Simulation (MCS), which relies upon a numerical/analytical model of the physical system, i.e. the pavement model and a probabilistic description of the design parameters represented by random variables or random fields. The high computational expense associated with the MCS, particularly in the case of random fields, is tackled by the use of meta-models based on the stochastic response surface methodology. The chapter outlines the steps followed to develop the meta-models in the form of Polynomial Chaos Equations (PCEs) and its extension to the Sparse PCE that can conveniently represent the spatial variability of the pavement fields. Chapter 4 deals with the probabilistic modelling of flexible pavements, where the design parameter and model uncertainties are quantified based on the available literature studies. The global sensitivity analysis, which aims to study the impact of the input uncertainty on the variation of a model output (critical pavement responses) through uncertainty propagation, is achieved by the construction of the Polynomial Chaos Equations (PCEs). To implement the global sensitivity analysis… Advisors/Committee Members: Sivakumar Babu, G L (advisor).

▼ The country has witnessed tremendous increase in the vehicle population and increased axle loading pattern during the last decade, leaving its road network overstressed and leading to premature failure. The type of deterioration present in the pavement should be considered for determining whether it has a functional or structural deficiency, so that appropriate overlay type and design can be developed. Structural failure arises from the conditions that adversely affect the load carrying capability of the pavement structure. Inadequate thickness, cracking, distortion and disintegration cause structural deficiency. Functional deficiency arises when the pavement does not provide a smooth riding surface and comfort to the user. This can be due to poor surface friction and texture, hydro planning and splash from wheel path, rutting and excess surface distortion such as potholes, corrugation, faulting, blow up, settlement, heaves etc. Functional condition determines the level of service provided by the facility to its users at a particular time and also the Vehicle Operating Costs (VOC), thus influencing the national economy. Prediction of the pavement deterioration is helpful to assess the remaining effective service life (RSL) of the pavement structure on the basis of reduction in performance levels, and apply various alternative designs and rehabilitation strategies with a long range funding requirement for pavement preservation. In addition, they can predict the impact of treatment on the condition of the sections. The infrastructure prediction models can thus be classified into four groups, namely primary response models, structural performance models, functional performance models and damage models. The factors affecting the deterioration of the roads are very complex in nature and vary from place to place. Hence there is need to have a thorough study of the deterioration mechanism under varied climatic zones and soil conditions before arriving at a definite strategy of road improvement. Realizing the need for a detailed study involving all types of roads in the state with varying traffic and soil conditions, the present study has been attempted. This study attempts to identify the parameters that affect the performance of roads and to develop performance models suitable to Kerala conditions. A critical review of the various factors that contribute to the pavement performance has been presented based on the data collected from selected road stretches and also from five corporations of Kerala. These roads represent the urban conditions as well as National Highways, State Highways and Major District Roads in the sub urban and rural conditions. This research work is a pursuit towards a study of the road condition of Kerala with respect to varying soil, traffic and climatic conditions, periodic performance evaluation of selected roads of representative types and development of distress prediction models for roads of Kerala. In order to achieve this aim, the study is focused into 2 parts. The first part deals with the…

The development of any country depends on accessibility and interconnectivity to different places through well connected transportation network. Road transportation is the most adaptable mode of transport under varied conditions of topography and hence top priority is given by the governments to improve road transportation facilities throughout the world by allocating huge capital investments. About 40% of total land in India is covered by clayey soils and inevitably the roads have to pass through such subgrades. Generally flexible pavements are preferred to rigid pavements due to less initial cost, smooth riding surface and easy maintenance. The design pavement thickness over clay subgrades is more due to their low soaked CBR values and so the construction cost is high. In spite of providing large pavement thickness, common failures noticeable in flexible pavements over clayey soils are excessive rutting, wavy surface, longitudinal cracking along wheel track and shear failure in edge region. Further, expansive clays pose serious problems to construction of pavements due to their shrink-swell behavior with moisture fluctuations and also make pavement construction expensive due to their very low strength in saturated condition resulting from swelling. Efforts are being made by researchers (Katti, 1979; Natarajan and Shanmukha Rao, 1979, Steinberg, 1992, Ramana Murthy, Prasada Raju) from time to time to improve the strength and stability of the clay subgrades in general and expansive soils in particular by stabilisation, reinforcing, moisture control and soil replacement techniques. The advent of geosynthetics has drawn the attention of highway engineers to consider them for use in pavement construction to enhance performance. Particularly, synthetic geotextile due to its multi functional behavior has been used in the control of reflection cracking in overlays, as separator- filter - drain at clay subgrades during the last two decades.

▼ The work presented in this thesis is aimed at improving the accuracy of one of the components of a flexible pavement design procedure commonly used in South Africa, namely the South African Mechanistic- Empirical Design Method. This is achieved through the development of a new design approach and permanent deformation model for the pavement subgrade. The new distress model for the pavement subgrade was developed from a comprehensive Accelerated Pavement Testing (APT) database on subgrade behaviour and permanent deformation that was generated by a fleet of Heavy Vehicle Simulators (HVSs) over 20 years of testing in South Africa. A literature review of the origin of the current subgrade design model that is used by the South African Mechanistic-Empirical Design Method revealed that that model is based on very little actual subgrade performance data. The model was also developed from the AASHO road test data and adjusted for South African conditions, based on general observations of subgrade behaviour without any calibration. Previous researchers have illustrated the potential of using Heavy Vehicle Simulator data to develop structural pavement design models and it was decided to apply a similar process to the permanent deformation of the pavement subgrade. The present investigation consisted of two components, namely, the evaluation of the resilient and the permanent deformation response of the pavement subgrade, the emphasis in this thesis being more on the permanent deformation response. A general, multi-dimensional empirical model was formulated for the permanent subgrade deformation and the characteristics of the model investigated based on previously published permanent deformation data and mathematical assessment. A set of 35 HVS tests for which suitable data were available was identified and additional field and laboratory tests were done on selected sites to improve the classification of the subgrade materials at these sites. Standard procedures were developed to present the pavement, instrumentation and load sequence data of each HVS test. A process for doing the initial analysis of the deflection and permanent MDD displacement data and presenting the data was also developed. In terms of the resilient response of the subgrade, it was shown that the vertical depth deflection and vertical strain could be modelled accurately if an appropriate set of resilient modulus values was selected for the pavement layers. A detailed investigation of the resilient response of selected HVS sections did, however, clearly illustrate the stress-dependent behaviour of subgrade material, resulting in resilient modulus values being determined, which were well outside the range that would normally be expected for natural gravel subgrade material. This research needs to be continued to enable the development of a comprehensive set of stress-dependent resilient modulus models for South African subgrade materials. The selection of an appropriate critical parameter that can be used as a predictor of permanent subgrade deformation was…

▼ In June 1994, a 150-m-long secondary road pavement section was built as part of the realignment of route 616 and 757 in Bedford County, Virginia to evaluate the performance of geosynthetically stabilized flexible pavements. The California Bearing Ratio (CBR) of the subgrade after construction was approximately 8%. The pavement section is was divided into nine individual sections, each approximately 15 m long. Sections one through three have a 100-mm-thick limestone base course (VDOT 21-B), sections four through six have a 150-mm-thick base course, and sections seven through nine have a 200-mm-thick base course. Three sections were stabilized with geotextiles and three with geogrids at the base course-subgrade interface. The remaining three sections were kept as control sections. One of each stabilization category was included in each base course thickness group. The hot-mix asphalt (HMA), SM-2A, wearing surface thickness was 78-90 mm. The outside wheel path of the inner lane was instrumented with strain gages, pressure cells, piezoelectric sensors, thermocouples, and moisture sensors. Section performances based on the instrumentation response to control and normal vehicular loading indicated that geosynthetic stabilization provided significant improvement in pavement performance. Generally, the measured pressure at the base course-subgrade interface for the geotextile-stabilized sections was lower than the geogrid-stabilized and control sections, within a specific base course thickness group. This finding agreed with other measurements, such as rut depth, ground penetration radar survey, and falling weight deflectometer survey. The control section (100-mm-thick base course) exhibited rutting that was more severe than the geosynthetically stabilized sections. Falling weight deflectometer back-calculation revealed consistently weaker subgrade strength for the geogrid-stabilized and control sections than for the geotextile-stabilized sections over the three year evaluation period. To quantitatively assess the extent of contamination, excavation of the first three sections in October 1997 revealed that fines present in the base course were significantly greater in the control and geogrid-stabilized section than in the geotextile-stabilized section. These findings led to the conclusion that the subgrade fine movement into the base layer when a separator is absent jeopardizes its strength. Further analysis of the field data showed that geotextile-stabilization may increase the service life of flexible secondary road pavements by 1.5 to 2 times. Finally, a new mechanistic-empirical flexible pavement design method for pavements with and without geosynthetics has been developed. Elasto-viscoelastic material characterization is used to characterize the HMA layer. The field results from Bedford County, Virginia project have been used to calibrate and validate the final developed design procedure. The concept of transition layer formed at the interface of base course and subgrade is also incorporated into the… Advisors/Committee Members: Al-Qadi, Imadeddin L.

Current pavement design procedures, for unbound layers, are often empirically based on previous research and/or based on in-situ experience. However, it is known that these unbound materials behave in a much more complex manner and that their behavior can have a significant impact during pavement design procedures. These materials are known to behave in a non-linear manner dependent on a range of factors including materials based and condition-based factors. Despite these known influencing factors pavement design procedures still most often continue to consider their behavior as either static and/or linear in nature most often for simplicity of calculation purposes. With the development of laboratory testing procedures, the development of constitutive based regression models commenced with multiple models aiming to most accurately define the behavior of these unbound materials based on mechanical or physical properties. Many constitutive models were developed over the years, however, their full potential for incorporation into pavement design procedures was not effective and feasible until the development of computer-based modeling programs that can more rapidly assess the predicted responses within pavement structures. Despite the potential for their inclusion into computer-based Finite Element Modeling (FEM) most often this relatively new arena of FEM based pavement design analysis still limits and overly simplifies unbound material behavior in modeling and analysis procedures. The majority of current research into these FEM analysis procedures limit their design of unbound pavement materials to a linear-isotropic based behavior as research has been focused more on the in-depth investigation of the upper bound pavement layers. This oversimplification can potentially have a significant effect of the pavements structures overall responses and is necessary to be included within FEM based pavement analysis procedures in order to more accurately predict pavement responses. This imbalance and lack of knowledge on the impact that the nonlinear anisotropic laboratory-based FEM modeling of unbound base materials may have on overall pavement responses is the focus of the current dissertation. With this knowledge gap in mind, the current research focuses on investigating the pavement responses through FEM analysis, incorporating nonlinear anisotropic laboratory-based modeling of the unbound base layer and the impact this characterization has on a wide array pavement structures and on their predicted pavement responses at critical locations.

This work evaluated the asphalt pavements of the Federal University of Viçosa (UFV), where functional and structural data were collected based on the rules of the Departamento Nacional de Infra-estrutura de Transportes (DNIT). The pavements of the campus were divided in homogeneous subparts. In function of technical characteristics of the pavements, some methodologies proposed by the DNIT had little changes because the DNITs rules used in this work were developed for using in pavements with technical standard, which were different of urban pavements. The functional analyses followed the roles of DNIT 006/2003 PRO e DNIT 009/2003 PRO, for the objectives and subjective superficial evaluations, respectively. In the deflectometer measurements, the methodology proposed by DNER ME 024/94 was used, which is referent to the determinations of the pavements deflection through the Benkelman beam. More than 80% of the subparts objectively evaluated received scores between terrible and bad. However, in the subjective evaluation, the subparts received scores between good and regular. In the subparts studied on the deflectometer evaluation, according to the roles of the structural evaluation of the DNIT, was observed the necessity of complementary studies, to obtain more data on such pavements and subsequently develop projects aiming the improvement of structural conditions of these pavements. This work consists of the preliminary study of structural conditions survey of the asphalted pavements of the UFV. The analyses and interpretation of the data related to the structural and superficial conditions of these pavements will be used to the supervision and planning of works to improve them.

Este trabalho consta de uma investigação sobre as vias asfaltadas do Campus da Universidade Federal de Viçosa (UFV), onde foram coletados dados funcionais e deflectométricos, baseando-se nas normas do Departamento Nacional de Infra-estrutura de Transportes (DNIT). Para tal, o sistema viário do Campus da UFV foi dividido em subtrechos homogêneos, e devido às características urbanas de suas ruas, algumas metodologias propostas pelo DNIT sofreram pequenas adaptações, pois as normas do DNIT empregadas no trabalho foram desenvolvidas para serem utilizadas em rodovias de padrão técnico diferente de vias urbanas. Para as análises funcionais foram seguidas às normas DNIT 006/2003 PRO e DNIT 009/2003 PRO, para a realização de avaliações superficiais objetivas e subjetivas, respectivamente. Nos trabalhos de medições deflectométricas, utilizou-se a metodologia proposta na norma DNER ME 024/94, que se refere à determinação das deflexões no pavimento através da viga Benkelman. Observou-se, nesta pesquisa, que mais de 80% dos subtrechos avaliados objetivamente receberam conceitos entre péssimo e ruim. Já por uma avaliação subjetiva, os subtrechos analisados ficaram com conceitos entre bom e regular. Quanto aos subtrechos analisados deflectométricamente, verificou-se, segundo as normas de avaliação estrutural do DNIT, a necessidade de estudos complementares,…

▼ The highway system serves as the most critical transportation link in the economic development of a nation. In Michigan, about 74% of all the commodities delivered annually are transported by heavy trucks. The Michigan Department of Transportation (MDOT) permits multi-axle (11 axles) heavy truck with gross vehicle weight (GVW) limit of 164,000 lb., unlike many states having GVW limit of 80,000 lb. The effect of these heavy truck loadings on pavements might accelerate the rate of deterioration for flexible and rigid pavement structures. More detailed knowledge of the interaction of trucks with the pavement structure is essential for better management of the highway network. In this study, pavement responses (stresses, strains and deflections) are evaluated under loading of multi-axles (11 axles) of heavy Michigan trucks including the impacts of different tire configurations and compared these responses with a standard 5-axle semi-trailer. The effects of truck loading, pavement thickness, joint system and material properties, and environmental (thermal) condition on the pavement damage caused by heavy Michigan trucks are evaluated. The major fatigue and faulting damage for rigid pavements as well as fatigue and subgrade rutting for flexible (asphalt) pavements are analyzed. The finite element method (FEM) based program ISLAB2000 has been used to compute rigid pavement responses (stresses or deflections). For flexible pavement responses (strains), multilayer elastic theory based program JULEA has been used. Results show that the standard truck has a higher fatigue damage potential under positive temperature gradient (during daytime) across slab. The Michigan trucks provide a greater fatigue damage potential under negative temperature gradient (during nighttime). Moreover, the positive temperature gradient yields a greater bending stress than that of negative temperature gradient and their critical stress locations are in the opposite surfaces. A thicker slab reduces both the fatigue and faulting damage of pavement. The standard truck has higher faulting damage potential. Moreover, the standard truck exhibits higher risk of both asphalt concrete (AC) fatigue and subgrade rutting damage for the flexible pavement when compared with Michigan trucks. As the number of axles increases, the heavy loads are distributed to larger areas and thus produce lower pavement damage Advisors/Committee Members: Jacob Hiller.

The study of innovative pavements is of significant importance in geotechnical engineering in Brazil, due to the continued need to increase the network of roadways. This requires optimized projects, not only for economic, but also for technical reasons. Technical solutions that use geosynthetics in asphalt overlays have been identified to minimize fatigue and reflective cracks. However, the majority of the application of this technology has ignored the possible additional structural benefits brought by the inclusion of geosynthetics as reinforcement in asphalt layers. The objective of this research is to assess the reinforcement benefits of geogrids placed within asphalt overlays on the structural performance of flexible pavements. In addition, this study investigates the tensile-strain response of geogrids under traffic conditions, induced by cyclic wheel loads generated by a new accelerated pavement testing facility (APT) that was specifically developed for this research. The APT facility consists of a large steel testing box, in which field-scale pavement layers could be constructed. Pavement materials included subgrade soil, aggregate base, hot mix asphalt concrete, asphalt emulsion and a PVA geogrid. Pavement performance was assessed by applying a cyclic wheel load pressure of 700 kPa to the pavement surface. The pavement sections investigated in this study included a geogrid-reinforced and an unreinforced asphalt overlay sections, a single new geogrid-reinforced asphalt layer, and a geogrid-reinforced asphalt overlay with reduced base course thickness. A variety of sensors were used to measure asphalt concrete strains, surface plastic and elastic displacements, and induced traffic loads. Displacements along the geogrid specimens were measured using a tell-tail system. As result, several reinforcement mechanisms of this technique could be quantified in the present study. Polymeric geogrid reinforcements were found to have considerably reduced strains developed at the bottom of asphalt layers, as well as to have reduced vertical stresses in pavement lower layers. Resistance to rutting and lateral movement induced by the geogrids were also clearly evidenced in the presented study. The measurement of displacements along the geogrid provided understanding of the distribution of strains during traffic loading. A mobilized length was identified in geogrid-reinforced sections, showing that the bonding between geogrids and asphalt layers and the stiffness of the geogrid ensured satisfactory performance of the pavement sections. The results also illustrated that the lateral restraining mechanisms effect is a governing mechanism to improve the performance of the asphalt layers by the development of shearing resistance with the geogrids. Overall, it was concluded that geogrids within asphalt overlays act as reinforcement and not merely to delay cracks, providing enhanced performance to flexible pavement structures.

▼ Atualmente se dispõe de uma série de métodos computacionais (softwares) que proporcionam a retroanálise de estruturas de pavimento. A maioria destes softwares utilizam as medidas de deflexão como parâmetro de análise e fazem comparação entre os valores de deflexão medidos e calculados para a obtenção dos valores de módulo de resiliência (MR) das camadas do pavimento. Para a realização das análises são exigidos como dados de entrada a espessura da camada, o coeficiente de Poisson (ν) e os módulos de resiliência iniciais dos materiais. Mesmo com todas essas ferramentas, o problema não garante uma solução fechada (única), pois várias configurações estruturais podem resultar numa mesma bacia deflectométrica. Interferem diretamente nos cálculos os valores adotados para as espessuras e os valores escolhidos para módulo de resiliência inicial. Desta forma, esta pesquisa tem como objetivo analisar a variabilidade dos valores de módulo de resiliência obtidos de programas computacionais de retroanálise, tendo como dados de entrada valores distintos de módulos de resiliência iniciais (módulos sementes). Para isso, utilizou-se os dados obtidos por meio de avaliações estruturais não-destrutiva (Falling Weight Deflectometer - FWD) e destrutiva (retirada de amostras) em subtrechos de três regiões distintas (anel viário da UFJF e rodovias federais concedidas BR-116/RJ CRT e BR-040/GO/MG Via040). Com as amostras coletadas em campo, foram realizados ensaios triaxiais dinâmicos para a obtenção do MR em laboratório. As bacias de deflexão e os valores de módulo de resiliência iniciais foram utilizados como dados de entrada nos softwares de retroanálise Elmod e BackMeDiNa. Ao variar então o MR inicial de uma das camadas em 100% como dado de entrada dos programas, pesquisou-se as diferenças percentuais nos MR finais calculados para as camadas. Estudou-se também a condição de interface (aderida/não-aderida) entre as camadas, relações entre módulos obtidos em laboratório e em campo, comparações entre dois programas de retroanálise distintos e correlações entre parâmetros de bacia e os módulos retroanalisados. Após os resultados fornecidos pelos softwares de retroanálise para um dos trechos, estes foram inseridos no software MeDiNa de dimensionamento de pavimentos flexíveis para se analisar a influência da variabilidade dos módulos sementes no processo de dimensionamento de reforço de pavimento, por meio do parâmetro percentagem de área trincada (%AT). Verificou-se que os módulos sementes têm influência significativa nos módulos finais no processo de retroanálise, com diferenças percentuais de até 137%, principalmente para as camadas de base e sub-base do pavimento. Mesmo com as diferenças obtidas nos valores de MR a partir da variação dos MR iniciais, verificou-se que não houve impacto significativo no projeto de dimensionamento de reforço, uma vez os diferentes conjuntos modulares resultaram em uma mesma espessura da camada de reforço, sendo que a diferença percentual entre os trincamentos previstos para o revestimento do pavimento foi… Advisors/Committee Members: Marques, Geraldo Luciano de Oliveira, Silva, Rafael Cerqueira, Riccio Filho, Mário Vicente, Motta , Laura Maria Goretti da.

▼ The empirical California Bearing Ratio (CBR) design method for flexible airfield pavements has been a mainstay for practicing engineers for decades. Its simplicity and proven performance makes it easy to use and reliable. However, design scenarios for increasingly larger aircraft have revealed a significant design shortfall at these extremely heavy and multi-wheeled loading conditions. This has driven a redevelopment of the CBR method to underpin it with a mechanistic load response of vertical stress at the subgrade surface instead of an equivalent single wheel load at the surface of the pavement. This response is correlated to an empirical failure model of pavement life developed from full-scale test data. This new design method has eliminated limitations in the original procedure that resulted in overdesigned pavements for large aircraft. However, any new method always leaves room for improvement. This thesis explored the development of the current failure model and identified an opportunity to refine it. The primary target of this modification was the concentration factor, an empirical modification to the Boussinesq stress distribution theory used in calculating the load response. The test data used to develop the current failure model was previously analyzed with a constant concentration factor for all test points. However, a more representative relationship of the concentration factor as a function of the subgrade CBR was available to better model soil behavior. After collecting additional test data beyond that used to develop the current failure model, a new failure model was developed that included the concentration factor as a function of CBR. In addition, it was shown, through comparison of nonlinear regression statistics, that a failure model developed using the concentration factor as a function of CBR provided failure model with a better fit to the test data than a model developed with a constant concentration factor.

Este relatório foi realizado no âmbito da unidade curricular de DIPRE (Dissertação/Projecto/Estágio) lecionada no Mestrado em Engenharia Civil – Infraestruturas, no Instituto Superior de Engenharia do Porto. O estágio foi realizado na Divisão Municipal de Obras e Iluminação Pública, na Câmara Municipal do Porto. Neste relatório procurou-se descrever e caracterizar todos os tipos de pavimentos, desenvolver e estudar novas técnicas de orçamentação e planeamento, e ainda analisar vários casos para mostrar a validade do que se realizou. Este relatório inicia-se com uma primeira parte de âmbito teórico, em que se faz referência aos diferentes tipos de pavimentos, analisando-se o seu comportamento, execução, patologias e métodos de dimensionamento. Para além disso faz-se a interpretação do Decreto-Lei nº 163/2006 e das questões de mobilidade urbana. Para o estágio foram necessárias diversas ferramentas de trabalho, não só fornecidas pela Divisão Municipal de Obras e Iluminação Pública, mas também propostas e exploradas pelo aluno. Com estas ferramentas conseguiu-se desenvolver um novo método de orçamentação, estudando os Rendimentos dos operários para um maior rigor nas estimativas de custo efetuadas. As soluções que se apresentam para mostrar o trabalho desenvolvido foram escolhidas de acordo com a sua importância e abrangência para demonstrar tudo o que foi acompanhado e realizado durante o estágio. Começando pela Rua do Dr. Magalhães Lemos, que foi selecionada porque houve a oportunidade de acompanhar e fiscalizar uma obra que contempla a execução de dois pavimentos distintos, o pavimento flexível e o rígido, em Betão Armado Contínuo. Optou-se também por selecionar dois casos de melhoria da acessibilidade no centro da cidade, porque foram dois projetos desenvolvidos pelo aluno em que se conseguiu explorar as diferentes decisões que teve de se tomar. Por fim, apresenta-se o estudo do dimensionamento da Rua de Santo Ildefonso de acordo com as diretrizes da Câmara Municipal do Porto no percurso académico.

▼ Pavement layer materials are typically assumed to be isotropic in determining pavement responses, such as stress and strain. The main benefit of the isotropic assumption is that stiffness defined by modulus of elasticity (E-value) is equal in all directions. In reality, stiffness along vertical and horizontal (i.e., and ) may vary due to density gradients in compacted layer materials caused by vertical compaction during construction. Therefore, pavement layer materials with different vertical and horizontal modulus (i.e., \u2260 ) are cross-anisotropic. Past studies have reported that degree of cross-anisotropy, ( ) ranges from 0.2 to 0.85 in Asphalt Concrete (AC) layers. Yet, the presence of cross-anisotropy is not considered in pavement layers for determining stress and strains, which are used for prediction of pavement distresses such as rutting and fatigue cracking. Ignoring the presence of AC cross-anisotropy may lead to an error in stress-strain calculations, and in pavement distress value predictions. To this end, this study examines the effects of cross-anisotropy on pavement stress-strain and thereby, evaluates the importance of cross-anisotropy in pavement design. In addition to cross-anisotropy, AC modulus is temperature and frequency dependent. Pavement temperature varies not only at different times over a day but also at different seasons over a year. Also, temperature is not constant over the depth of an AC layer which leads to a non-homogenous distribution of AC stiffness. AC modulus varies due to different loading frequencies caused by variable speed of moving vehicles. Unbound layers such as base and subbase are stress-dependent. The stiffness of an unbound layer differs at different months over a year due to varying moisture contents. This study considers all of these factors such as temperature, frequency, and moisture with material cross-anisotropy through laboratory testing and finite element modeling. In this study, a dynamic Finite Element Model (FEM) is developed based on the geometry of an instrumented pavement section at Milepost (MP) 141 on I-40, Rio Puerco, New Mexico and deflections, stress, and strains are predicted under truck tire pressure. Two different material models are employed: (i) generalized cross-anisotropic and temperature dependent viscoelastic model, and (ii) nonlinear elastic and stress-dependent model. The first one is for the AC layer whereas the second one is for unbound layers such as base and subbase courses. In this study, dynamic modulus tests were conducted in the laboratory on field-compacted vertical and horizontal AC cores to determine the parameters required for developing the generalized cross-anisotropic viscoelastic model. Resilient modulus tests were conducted on granular aggregates collected from the base and subbase layers to develop nonlinear elastic and stress-dependent material model. After integrating these material models, the dynamic FEM is simulated under a Falling Weight Deflectometer (FWD) test type load (79.6 psi over a circular area with 6… Advisors/Committee Members: Tarefder, Rafiqul, Ng, Tang-Tat, Maji, Arup, Shen, Yu-Lin.

▼

A utilização da tela de aço como reforço de pavimentos asfálticos no combate ao trincamento por reflexão é uma alternativa utilizada desde 1980 em países europeus. Uma revisão da literatura a respeito de sua utilização na reabilitação de pavimentos asfálticos, mostra que, a sua utilização acaba diminuindo o aparecimento de trincas nas camadas de revestimento, agindo como uma barreira contra a sua propagação, oferece resistência ao cisalhamento especialmente sob elevadas tensões e ainda, melhora a resistência à fadiga contribuindo para a longevidade do pavimento. Entretanto, o potencial de sua utilização tem sido pouco investigado em rodovias brasileiras. Neste contexto, insere-se esta pesquisa com o objetivo de avaliar o efeito do reforço gerado pela inserção da tela em revestimentos asfálticos para o uso em pavimentos flexíveis, com o propósito de tornar as estruturas rodoviárias menos onerosas com consequente aumento da sua vida útil. Para isso, foi realizada uma pesquisa visando à análise do seu desempenho em um trecho experimental localizado na rodovia SP-354, no Estado de São Paulo entre as cidades de Campo Limpo Paulista e Jarinu, fundamentado nas melhores práticas internacionais, recorrendo à observação em campo e laboratório, análise por meio de ensaios de módulo de resiliência e cálculos por retroanálise para verificação do efeito da inserção da tela, ainda propondo, uma metodologia de dimensionamento estrutural de reforço de pavimentos asfálticos considerando a faixa de valores de módulo de resiliência integrados com a tela e o fator de deflexão (K) para cálculo de espessura de reforço. Conclui-se que esta técnica de reforço tem potencial para prolongar a vida útil de revestimentos asfálticos em pavimentos flexíveis, com benefícios também para o desempenho da camada na fase pós-trincamento. Foram obtidos modelos que permitem dimensionar o revestimento asfáltico com o propósito de avaliar o efeito da tela de aço na zona tracionada da camada. Por fim, foi verificada através de um estudo de viabilidade técnica/econômica que a incorporação da tela de aço em pavimentos flexíveis é uma alternativa eficaz e de adequada viabilidade técnica e econômica.

The use of the steel mesh as reinforcement of asphalt pavements to combat reflective cracks by reflection is an alternative used since 1980 in European countries. A review of the literature on the use of the steel mesh in the rehabilitation of asphalt pavements shows that its use prevents the appearance of cracks acting as a barrier against its propagation, offers resistance to shearing especially under high tensions and also improves the resistance to fatigue contributing to the longevity of the pavement. However, the potential if its use has been little investigated in Brazilian highways. In this context this project is to develop a new technology for road construction and rehabilitation. The idea is to use steel mesh reinforcement in asphalt roads in order to make road structures more cost effective by improving the lifetime of new constructed roads and…

▼ There is a growing interest for the use of mechanistic procedures and analytical methods in the design and evaluation of pavement structure rather than empirical design procedures. The mechanistic procedures rely on predicting pavement response under traffic and environmental loading (i.e., stress, strain, and deflection) and relating these responses to pavement field performance. A research program has been developed at the Center for Pavement and Transportation Technology (CPATT) test track to investigate the impact of traffic and environmental parameters on flexible pavement response. This unique facility, located in a climate with seasonal freeze/thaw events, is equipped with an internet accessible data acquisition system capable of reading and recording sensors using a high sampling rate. A series of controlled loading tests were performed to investigate pavement dynamic response due to various loading configurations. Environmental factors and pavement performance were monitored over a two-year period. Analyses were performed using the two dimensional program MichPave to predict pavement responses. The dynamic modulus test was chosen to determine viscoelastic properties of Hot Mix Asphalt (HMA) material. A three-step procedure was implemented to simplify the incorporation of laboratory determined viscoelastic properties of HMA into the finite element (FE) model. The FE model predictions were compared with field measured pavement response. Field test results showed that pavement fully recovers after each wheel pass. Wheel wander and asphalt mid-depth temperature changes were found to have significant impact on asphalt longitudinal strain. Wheel wander of 16 cm reduced asphalt longitudinal strains by 36 percent and daily temperature fluctuations can double the asphalt longitudinal strain. Results from laboratory dynamic modulus tests found that Hot Laid 3 (HL3) dynamic modulus is an exponential function of the test temperature when loading frequency is constant, and that the HL3 dynamic modulus is a non-linear function of the loading frequency when the test temperature is constant. Results from field controlled wheel load tests found that HL3 asphalt longitudinal strain is an exponential function of asphalt mid-depth temperature when the truck speed and wheel loading are constant. This indicated that the laboratory measured dynamic modulus is inversely proportional to the field measured asphalt longitudinal strain. Results from MichPave finite element program demonstrated that a good agreement between field measured asphalt longitudinal strain and MichPave prediction exists when field represented dynamic modulus is used as HMA properties. Results from environmental monitoring found that soil moisture content and subgrade resilient modulus changes in the pavement structure have a strong correlation and can be divided into three distinct Seasonal Zones. Temperature data showed that the pavement structure went through several freeze-thaw cycles during the winter months. Daily asphalt longitudinal…

▼ A majority of the primary roadways in the United States are constructed using hot-mix asphalt (HMA) placed over a granular base material. The strength of this pavement system is strongly influenced by the local environmental conditions. Excessive moisture in a granular base layer can cause that layer to lose its structural contribution by reducing the area over which loading may be distributed. Excessive moisture and fine particles can be transported by hydrostatic pressure to the surface layers, thus reducing the strength of the overlying HMA by contamination. Moisture in the surface HMA layers can cause deterioration through stripping and raveling. In addition, as HMA is a viscoelastic material, it behaves more as a viscous fluid at high temperatures and as an elastic solid at low temperatures. Between these two temperature extremes, a combination of these properties is evident. Thus, understanding the environmental effects on flexible pavements allows better prediction of pavement performance and behavior under different environmental conditions. As part of the ongoing pavement research at the Virginia Smart Road, instrumentation was embedded during construction to monitor pavement response to loading and environment; moisture content of the granular base layers and temperature of the HMA layers were among the responses monitored. The Virginia Smart Road, constructed in Blacksburg, Virginia, is a pavement test facility is approximately 2.5km in length, of which 1.3km is flexible pavement that is divided into 12 sections of approximately 100m each. Each flexible pavement section is comprised of a multi-layer pavement system and possesses a unique structural configuration. The moisture content of aggregate subbase layers was measured utilizing two types of Time-Domain Reflectometry (TDR) probes that differed in their mode of operation. The temperature profile of the pavement was measured using thermocouples. Data for the moisture content determination was collected and results from two probe types were evaluated. In addition, the differences in the moisture content within the aggregate subbase layer due to pavement structural configuration and presence of a moisture barrier were investigated. It was shown that the two TDR probe types gave similar results following a calibration procedure. In addition to effects due to pavement structure and subgrade type, the presence of a moisture barrier appeared to reduce the variability in the moisture content caused by precipitation. Temperature profile data was collected on a continuous basis for the purpose of developing a pavement temperature prediction model. A linear relationship was observed between the temperature given by a thermocouple near the ground surface and the pavement temperature at various depths. Following this, multiple-linear regression models were developed to predict the daily maximum or minimum pavement temperature in the HMA layers regardless of binder type or nominal maximum particle size. In addition, the measured ambient… Advisors/Committee Members: Al-Qadi, Imadeddin L. (committeechair), Trani, Antoino A. (committee member), Flintsch, Gerardo W.

▼ The purpose of this research was to evaluate the dynamic variation in asphalt pavement critical responses due to dynamic tire load variations. An attempt was also made to develop generalized regression equations to predict the dynamic response variation in flexible pavement under various dynamic load conditions. The study used an extensive database of computed pavement response histories for five different types of sites (smooth, rough, medium rough, very rough and severely rough), two different asphalt pavement structures (thin and thick) at two temperatures (70 °F and 104 °F), subjected to a tandem axle dual tire at three speeds 25, 37 and 50 mph (40, 60 and 80 km/h). All pavement responses were determined using the 3D-Move Analysis program (Version 1.2) developed by University of Nevada, Reno.A new term called Dynamic Response Coefficient (DRC) was introduced in this study to address the variation in critical pavement responses due to dynamic loads as traditionally measured by the Dynamic Load Coefficient (DLC). While DLC represents the additional varying component of the tire load, DRC represents the additional varying component of the response value (standard deviation divided by mean response). In this study, DRC was compared with DLC for five different sites based on the roughness condition of the sites. Previous studies showed that DLC varies with vehicle speed and suspension types, and assumes a constant value for the whole pavement structure (lateral and vertical directions). On the other hand, in this study, DRC was found to be significantly varied with the asphalt pavement and function of pavement structure, road roughness conditions, temperatures, vehicle speeds, suspension types, and locations of the point of interest in the pavement.A major contribution of the study is that the variation of pavement responses due to dynamic load in a flexible pavement system can be predicted with generalized regression equations. Fitting parameters (R2) in the rage of 0.60 to 0.87 were observed the DRC predictive equations. In addition, verification of those generalized equations was evaluated using different sets of asphalt pavement structures and pavement materials. The differences between calculated and predicted values were found to be within ±20% for the maximum tensile strain and ±30% for the maximum compressive strain in the asphalt layer.

▼ Pavement rutting is one of the most important types of pavement distress that affect road safety and ride quality. Therefore, the primary objective of this study was to develop pavement rutting empirical models for different climate zones to predict pavement rutting on granular base based on LTPP data. Flexible pavements with granular base course were considered for this study. These models lead to better understanding of rutting phenomena and the factors that may have affect in pavement rutting. In addition, these models will help state and local transportation agencies make accurate decisions for maintenance, rehabilitation and reconstruction of pavement. To develop a reliability-based methodology for pavement rutting prediction models, nine main steps were performed. These steps include reviewing previous studies, reviewing data sources of pavement performance, selecting the variables that may have effect pavement rutting, selecting the test sections at each climate zone, building the research database, verifying the data, analyzing the data, validating the models, and obtaining the final form of the models. After the data were studied for missing and abnormal data, multiple regression analysis was performed to develop empirical models. Five models were developed based on the GPS-1 sections in wet freeze zone, dry freeze zone, wet no-freeze zone, dry no-freeze zone, and different climate zone combined. The study indicated that traffic data was the most important factor in wet freeze zone model. The second significant factor in the model was SN followed by VTM, VMA, and Marshall stiffness. In dry freeze zone model, VMA is the most significant factor affecting pavement rutting. Traffic loads are the second significant factor affecting pavement rutting followed by Marshall stiffness and freeze index. The contributing factors in wet no-freeze zone model are VTM which is the most significant factor, SN, and traffic loads. In dry no-freeze zone, the developed model includes traffic loads as the most important factor that affect pavement rutting followed by number of days above 32 °C. As in wet no-freeze zone, VTM is the most significant factor that has affect in pavement rutting in the proposed model developed based on combined data from different climate zones. The model also includes traffic loads as the second significant factors affecting pavement rutting and SN. Advisors/Committee Members: Mumtaz Usmen.

▼ Weak soil is a common problem in road construction. Whether it is a temporary access road or a permanent road built over a weak subgrade, a large deformation of the subgrade can lead to deterioration of the paved or unpaved surface. Geosynthetics offer a potentially economical solution for stabilizing roads built over weak soil. Three sets of testing programs were be conducted in this study.The first testing program includes conducting accelerated load testing of full-scale geosynthetic reinforced test lanes using rolling wheel load facility; the second program included conducting laboratory cyclic plate loading test on geosynthetic reinforced test sections constructed inside a steel box facility, and the third program included cyclic plate loading test on full-scale test lane sections. An extensive in-situ and laboratory testing was performed before the construction of the test sections and after each stage of pavement construction to assess the strength, stiffness of the pavement layers. Both the full-scale pavement test lane sections and in-box laboratory pavement test sections were instrumented with several sensors to measure the load associated and associated environmental responses. The experimental test results demonstrated that the inclusion of geosynthetics in pavement to reinforce the base and or stabilize the subgrade can significantly enhance the pavement performance in terms of reducing the permanent deformation of pavement layers. The inclusion of geosynthetics in pavement can help redistribute the load and change the stress concentration on top of subgrade layer. The benefits of geosynthetic reinforcement were quantified, within the context of the AASHTOWare Pavement ME Design guide and AASHTO 1993, in terms of increasing the resilient modulus of base course layer and/or reducing the thickness of base aggregate layer in pavement structure.The results for three test experiments showed an increase in traffic benefit ratio when including geosynthetic in pavement.Also, include geosynthetic showed appreciable benefit on reducing the permanent deformation of base layer subgrade in this study. Four empirical models were developed by using nonlinear regression to evaluate and quantify the benefits of using geosynthetics in pavement built over weak subgrade. The first model was developed to quantify the traffic benefit ratio (TBR). The second model was developed to quantify the base course reduction(BCR). The third model was developed to quantify the resilient modulus increase by using the geosynthetics to reinforce the base layer. The fourth model was developed to quantify the increase in resilient modulus by using the geosynthetics to stabilize the subgrade.Furthermore, The developed models were verified with experimental data to predict the amount of each model.

▼ Particle transport and its subsequent deposition in porous media play a significant role in the performance of civil infrastructure such as pavements. Pavement structure typically consists of an asphalt concrete or concrete surface layer, underlying granular layers (subbase and/or base), and a compacted subgrade soil layer. As the subgrade is saturated during wet seasons, cyclic loading caused by heavy traffic may lead to pumping of fine particles from the subgrade into the granular layers. Additionally, in rigid pavements, the repeated traffic loading may also result in redistribution of materials underneath the slabs, which contributes to faulting of rigid pavement slabs. Pumping of fines negatively impacts the performance and service life of the pavement and ultimately may lead to failure. The main objectives of this research are to (1) investigate occurrence of migration of fines and simulate and quantify the magnitude and rate of such migration in both flexible and rigid pavements and for different classes of roadways, (2) evaluate the effectiveness of geotextiles as a separation and filtration layer in preventing subgrade fines migration, and (3) understand the mechanisms of fines migration in pavement and provide a reasonable prediction of the amount of fines migration using a numerical model on particle transport in porous media. The cyclic traffic loading is simulated on geometrically-scaled models of flexible and rigid pavements representing a typical collector road and interstate highways using a one-third-scale Model Mobile Load Simulator (MMLS3), an accelerated pavement testing (APT) device. The pavement sections are constructed on partially saturated aggregate subbase overlying non-plastic saturated silt as subgrade. To evaluate the effectiveness of geotextile separation and filtration in reducing subgrade fines migration, identical tests simulating flexible collector road and rigid interstate highway are repeated, except that a geotextile layer is placed at the interface of subgrade and subbase layers. The results obtained from the tests with and without geotextile separator layer are then compared. The lab testing reveals that, under repeated traffic loading, a significant amount of fines migrated into the subbase. More migration occurs in the simulated collector road than in the interstate highway. The subgrade fines migration in mass percentage increases with the simulated traffic loading cycles. The resulting gradation of subbase also varies with the depth in the subbase, with more fines deposited in the lower section (closer to the subgrade) than in the upper section of the subbase. In the jointed rigid pavement, more fines accumulated in the subbase beneath the approach slab than beneath the leave slab, confirming that migration of fines counter to the direction of traffic occurs when the load moves to the leave slab. A geotextile separation layer at the subgrade-subbase interface can be used as an effective means to reduce pumping of subgrade fines in pavement by providing both separation and… Advisors/Committee Members: Shelley Marie Stoffels & Ming Xiao, Dissertation Advisor/Co-Advisor, Shelley Marie Stoffels & Ming Xiao, Committee Chair/Co-Chair, Tong Qiu, Committee Member, Shimin Liu, Committee Member, Shimin Liu, Outside Member.
