Ce travail de thèse s'articule autour de plusieurs variations sur le thème du rebond d'une goutte d'eau sur une surface non-mouillante. Nous engendrons des rebonds spéciaux que nous caractérisons expérimentalement. Notre analyse de ces rebonds se concentre sur la mise en évidence des paramètres et des phénomènes physiques contrôlant leur extension spatiale et temporelle, deux quantités qu'il est important de comprendre tant d'un point de vue fondamental qu'appliqué. Nous étudions, dans un premier temps, les effets de la géométrie du substrat sur le rebond d'une goutte d'eau. Nous montrons qu'une modification locale, l'ajout d'une macrotexture ponctuelle, crée un mécanisme de rebond nouveau que nous associons à une réduction du temps de contact d'un facteur 2. Nous réalisons également des impacts sur des substrats coniques et sphériques en mettant en avant les différences et les similitudes avec les impacts sur une surface plane. Dans un second temps, nous nous intéressons aux effets créés par un substrat mobile. Nous étudions l'impact de gouttes sur des surfaces déformables et comprenons comment l'échelle de temps du rebond est influencée par une interaction entre celle de la goutte et celle du substrat. Nous discutons aussi l'influence de la déformation du substrat sur le splash. Notre étude de l'influence du mouvement s'est poursuivie en utilisant des surfaces rigides auxquelles nous pouvons imposer un déplacement vertical. En soumettant des gouttes initialement au repos à un mouvement impulsionnel, nous engendrons de surprenantes cavités coniques dont nous modélisons la dynamique. Cette expérience permet de faire un constat étonnant, la faible adhésion des surfaces superhydrophobes est nécessaire à l'obtention des cavités. Nous réalisons des impacts sur une surface dont le déplacement peut-être déclenché au moment du contact entre le liquide et le solide à l’aide du signal provenant d’un capteur de force de type MEMS. Nous atteignons des temps de contact extrêmement réduits, de l’ordre de 20% de celui observé sur le même substrat sans mouvement. Enfin, nous modifions le liquide et non le substrat. Nous montrons que des gouttes jusqu'à 200 fois plus visqueuses que l'eau peuvent rebondir sur des matériaux superhydrophobes.

This thesis revolves around the ability of liquid drops to bounce off superhydrophobic materials. We generate special rebounds and characterize them experimentally.We focus on finding the relevant physical phenomena to describe the temporal and spatial extension of such events, both quantities being of importance from the fundamental and applied point of vue. First, we study the influence of the susbtrate geometry. We modify the surface locally, by introducing a singular macrotexture, and show that it leads to a new bouncing mechanism that shortens the contact time by a factor typically 2. We also modify the substrate at the size of the drop. We perform impacts on non wetting cones and spheres and compare them to what is observed on a flat surface. Then, we study the effect of…

Uma dificuldade que acomete as empresas de construÃÃo pesada em relaÃÃo Ã seguranÃa viÃria Ã atingir valores mÃnimos de aderÃncia exigidos em campo para o revestimento de pavimentos. Valores mÃnimos de microtextura, ensaiados atravÃs do pÃndulo britÃnico, e faixas de macrotextura, ensaiadas pelo ensaio de mancha de areia, sÃo encontrados no Manual de RestauraÃÃo de Pavimentos AsfÃlticos do DNIT de 2006. Nas situaÃÃes onde esses parÃmetros ligados Ã aderÃncia sÃo controlados, o revestimento precisa ser reexecutado quando a micro e a macrotextura nÃo se aproximam do exigido pelas normas. Trata-se de um problema apenas observado durante a fase de construÃÃo, uma vez que nÃo se determina a aderÃncia em laboratÃrio, na fase de projeto. Pesquisas apontam que as mudanÃas nas propriedades dos agregados e na granulometria podem afetar a micro e a macrotextura da camada de rolamento. A fim de contribuir na questÃo da aderÃncia, buscando a previsÃo desse parÃmetro ainda indiretamente em laboratÃrio, objetivou-se desenvolver uma metodologia capaz de testar granulometrias para verificar o efeito das fraÃÃes dos materiais das peneiras nesta aderÃncia da superfÃcie do pavimento. A metodologia proposta consistiu em comparar a textura da massa asfÃltica compactada em campo e em laboratÃrio utilizando os ensaios de mancha de areia e de pÃndulo britÃnico. Objetivou-se, ainda, desenvolver um modelo capaz de predizer o valor de macrotextura da camada de rolamento atravÃs de granulometrias das misturas asfÃlticas estudadas. O modelo foi composto por dados de fraÃÃes retidas entre as peneiras nÂ40 e 3/8â. Os principais resultados obtidos levaram Ã conclusÃo de que a metodologia desenvolvida em laboratÃrio foi consistente no aspecto de microtextura entre campo e laboratÃrio. Em relaÃÃo ao modelo, houve uma correlaÃÃo considerada satisfatÃria, portanto, indicando o potencial da previsÃo da macrotextura ainda na fase de projeto a partir da granulometria a adotar.

A difficulty that affects pavement contractors regarding road safety is to achieve minimum values of surface friction required to the pavement in the field. Minimum values of microtexture tested through the British pendulum and ranges of macrotexture tested by the sand patch test are found in the DNIT Manual of Asphalt Pavements Restoration (2006). In situations where the friction parameters are controlled, oftentimes the pavement needs to be reexecuted when the micro and macrotexture do not meet the required values. This is a problem only observed during the construction phase as friction is not determined indirectly in the laboratory during the design phase. Research indicates that changes in the properties of the aggregates and the particle size can affect the microtexture and macrotexture of the surface course. In order to contribute to the topic of friction, seeking the prediction of this parameter in the laboratory, this work aimed to develop a methodology capable of evaluating gradations and the effect of the…

Ce travail de recherche a pour objectif général de proposer un modèle de mise en relation du design émotionnel avec la macrotexture et les matériaux pour aider les concepteurs à la sélection de finitions pour les produits industriels. Cette modélisation vise à valoriser le produit à travers l’exploration des mécanismes sensoriels, sémantiques et émotionnels, qui interviennent lors de la perception du produit par le consommateur. Le processus perceptif est ainsi pris en compte à travers différents modalités sensorielles de manière à enrichir le processus de conception. Le secteur d’application de notre recherche a été le secteur automobile, avec le produit « volant ». Ce produit a été analysé dans la catégorie Grand Public. Dans cette catégorie, les matériaux ont été analysés sur un ensemble de 7 différents modèles de volants avec une population française et brésilienne. Par ailleurs, différents paramètres techniques tels que, la dureté, la rugosité et la dissipation thermique, ont été pris en compte dans la mise en relation pour renforcer la communication entre les domaines du Design et l’Ingénierie.

This research has the overall goal to propose a model linking emotional design with macrotexture and materials to help designers in the selection of finishes for industrial products. This model aims to promote the product through the exploration of sensory, semantic and emotional mechanisms, involved in the perception of the product by the consumer. The perceptive process is thus considered through different sensory modalities to enrich the design process. The application sector of our research was the automotive sector, with the product "steering wheel". This product was analyzed in the General Public category. In this category, the materials were analyzed within a set of 7 different steering wheels models by a population of French and Brazilian users. Moreover, different technical parameters such as, hardness, roughness and heat dissipation have been taken into account in the linking to strengthen communication between the fields of Design and Engineering.

▼ Pavement macrotexture has been shown to influence a range of safety and comfort issues including wet weather friction, splash and spray, ambient and in-vehicle noise, tire wear, and rolling resistance. While devices and general guidance exist to measure macrotexture, the wide-scale collection and use of macrotexture is neither mandated nor is it typically employed in the United States. This work seeks to improve upon the methods used to calibrate, collect, pre-process, and distill macrotexture data into useful information that can be utilized by pavement managers. This is accomplished by 1. developing a methodology to evaluate and compare candidate data collection devices; 2. plans and procedures to evaluate the accuracy of high-speed network data collection devices with reference surfaces and measurements; 3. the development of a method to remove erroneous data from emerging 3-D macrotexture sensors; 4. development of a model to describe the change in macrotexture as a function of traffic; 5.finally, distillation of the final collected pavement surface profiles into parameters for the prediction of important pavement surface properties aforementioned. Various high-speed macrotexture measurement devices were shown to have good repeatability (between 0.06 to 0.09mm MPD) and interchangeability of single-spot laser dfevices was demonstrated via a limits of agreement analysis. The operational factors of speed and acceleration were shown to affect the resulting MPD of several devices and guidelines are given for vehicle speed and sensor exposure settings. Devices with single spot and line lasers were shown to reproduce reference waveforms on manufactured surfaces within predefined tolerances. A model was developed that predicts future macrotexture levels (as measured by RMS) for pavements prone to bleeding due to rich asphalt content. Finally, several previously published macrotexture parameters along with a suite of novel parameters were evaluated for their effectiveness in the prediction of wet weather friction and certain types of road noise. Many of the parameters evaluated outperformed the current metrics of MPD and RMS. Advisors/Committee Members: Flintsch, Gerardo W. (committeechair), de Leon Izeppi, Edgar D.

▼ When an ultrasonic wave propagates in polycrystalline materials, the wave is scattered on grain boundaries and the scattered waves carry important information on material microstructure, e.g. grain size and texture. Using grain scattering information for nondestructive testing purposes can be useful as quality control in many manufacturing processes. In particular, measurement and interpretation of ultrasonic scattering can be very useful in the development of practical methods for nondestructive ultrasonic characterization of microtextured regions in titanium alloys that are widely used for aeroengine components. Ultrasonic scattering and scattering-induced ultrasonic attenuation are two measurable ultrasonic characteristics that can be employed for material microstructures characterization. Most past studies address ultrasonic attenuation and scattering in polycrystals with macroscopic isotropy or simple artificial textures and equiaxed grains of high crystallographic symmetry (cubic or hexagonal). However, most manmade materials, as a result of thermomechanical processing, exhibit nonequiaxed grains and complex forms of macroscopic texture.One objective of this dissertation is to provide a better understanding of ultrasonic propagation and scattering in textured polycrystyals. In this dissertation, general attenuation and scattering models are developed for polycrystals with arbitrary macrotexture and ellipsoidal grain shape with triclinic symmetry. The attenuation coefficients were derived in the Born approximation by generalizing previous theoretical models that were suitable for equiaxed grains and uniaxial hexagonal textures. The general scattering coefficients were obtained from the integrand of the attenuation coefficients. The second major objective is to ultrasonically characterize the microtextured regions (MTRs) in Ti alloys which is a result of orientation clustering of crystallites and leads to a reduction of dwell fatigue properties of the material. The models developed are extended to titanium alloys with those dual-scale microstructures. The third objective of this dissertation is to establish an inversion methodology to robustly reconstruct material characteristics from ultrasonic attenuation and backscattering measurements. By using a combination of the attenuation-to-backscattering ratios and directional backscattering ratios, an inversion procedure is developed for a complete reconstruction of MTR sizes and its effective elastic parameters. The experimental methodology and the system calibration method are described for the near field of the ultrasonic transducer measurements. Examples of measurements and application of inversion models to typical titanium alloy samples are given. It is shown that in general, the MTR sizes and the microtexture parameters determined by ultrasonic inversion models are in reasonable agreement with those measured by others on the same samples by destructive electron backscatter diffraction (EBSD) characterization methods.

A infraestrutura aeroportuária assume papel de destaque tratando-se de segurança de vôo, dado ao grande percentual de ocorrência de acidentes nas operações de aterragem e descolagem. Os pavimentos aeroportuários são responsáveis por promover características adequadas para garantir a segurança dos utentes nessas operações. A preocupação geral quanto às características funcionais do pavimento está relacionada com a aderência entre o pneu da aeronave e a superfície da pista de aterragem e descolagem. Objetiva-se a obtenção de revestimentos a partir de misturas betuminosas que assegurem a aderência pneupavimento, por meio da combinação da microtextura e macrotextura, criando propriedades de atrito adequadas à variação da velocidade das aeronaves e à adversidade das situações climáticas. A estrutura do pavimento aeroportuário pode variar entre pavimento rígido e flexível, devido à ordem técnica e económica. A escolha do tipo de pavimento é justificada conforme o tipo de utilização do mesmo (pistas, caminhos de circulação, áreas de estacionamento). O presente trabalho apresenta o estudo sobre o uso de misturas betuminosas do tipo camada porosa de atrito (CPA), que corresponde a uma camada betuminosa aberta, como camada de revestimento de pavimentos aeroportuários. O trabalho desenvolve-se através do estudo das especificações técnicas para a utilização desse tipo de camada, bem como suas vantagens frente a revestimentos convencionais, que fundamentam sua aplicação como revestimento de pavimentos aeroportuários, e as limitações para seu uso. Como estudo de caso será analisada a aplicação dessa mistura betuminosa aberta na obra de recapeamento na pista de aterragem e descolagem do Aeroporto de Catoca, a partir de documentos que relatam patologias ocorridas após um ano da execução. Pretende-se, também, a identificação das possíveis causas dessas patologias por meio da comparação entre a descrição dos documentos fornecidos pela empresa responsável pelo projeto e as especificações técnicas apresentadas nesse trabalho.

The airport infrastructure assumes a prominent role in the case of flight safety, given to the high percentage of accidents in landing and taking-off operations. The airport pavements are responsible for promoting adequate characteristics to ensure the safety of users in such operations. The general concern about the pavement´s functional characteristics relates to the adhesion between the aircraft tire and the surface of the landing and taking-off runway. The goal is to obtain coatings from asphalt mixtures to ensure the tire-pavement grip, by combining microtextures and macrotextures in order to create friction properties suitable for both aircraft speed variation and climate adversity situations. The structure of the airport pavement can be either rigid or flexible, due to technical and economic issues. The choice of the kind of pavement is justified according to the type of its use (runways, taxiways, parking areas). This paper presents a study on the use of plant mixed of porous friction course (PFC), which…

A cidade de Manaus apresenta uma das maiores taxas de crescimento médio da frota de veículos, segundo dados do DENATRAN. Nos últimos 10 anos, a frota de automóveis aumentou de 124.840 (2003) para 297.473 automóveis (2013) e 3.179 ônibus (2003) para 7.398 ônibus (2013). Isto equivale a um aumento de 138 %. Ademais, ainda, segundo o DENATRAN, em 2003, Manaus tinha 220.816 veículos. Em 2013, Manaus já possui 551.455 veículos registrados na sua frota municipal, o que equivale a um aumento de quase 150 %. Como consequência deste crescimento, as vias da cidade apresentam-se com sua capacidade de fluxo inoperante e, visualmente, com seus pavimentos totalmente deformados. Neste sentido, procurou-se realizar, nesta pesquisa, uma avaliação estrutural dos pavimentos das principais vias da cidade (Av. Constantino Nery, Av. Djalma Batista, Av. Recife, Av. Paraíba e Av. Efigênio Sales), empregando a técnica FWD (Falling Weight Deflectometer) no diagnóstico das estruturas dos pavimentos das referidas vias. Os resultados obtidos mostraram que as estruturas daqueles pavimentos ainda apresentam a condição de suportar as solicitações de carga de tráfego a elas aplicadas, visto que sua qualidade estrutural, obtida pela técnica mencionada, apresentou-se em boas condições, em função dos pavimentos terem apresentado deflexões máximas inferiores às admissíveis, bem como raios de curvatura muito superiores a 100 m. Como complemento à análise estrutural, realizou-se análise das condições funcionais do revestimento com relação à aderência pneu-pavimento, a qual apresentou valores para microtextura e macrotextura bem fora dos intervalos recomendados pelas normas.

▼ One of the most important objectives for transportation engineers is to understand pavement surface properties and their positive and negative effects on the user. This can improve the design of the infrastructure, adequacy of tools, and consistency of methodologies that are essential for transportation practitioners regarding macrotexture characterization. Important pavement surface characteristics, or tire-pavement interactions, such as friction, tire-pavement noise, splash and spray, and rolling resistance, are significantly influenced by pavement macrotexture. This dissertation compares static and dynamic macrotexture measurements and proposes and enhanced method to quantify the macrotexture. Dynamic measurements performed with vehicle-mounted lasers have the advantage of measuring macrotexture at traffic speed. One drawback of these laser devices is the presence of 'spikes' in the collected data, which impact the texture measurements. The dissertation proposes two robust and innovative methods to overcome this limitation. The first method is a data-driven adaptive method that detects and removes the spikes from high-speed laser texture measurements. The method first calculates the discrete wavelet transform of the texture measurements. It then detects (at all levels) and removes the spikes from the obtained wavelet coefficients (or differences). Finally, it calculates the inverse discrete wavelet transform with the processed wavelet coefficients (without outliers) to obtain the Mean Profile Depth (MPD) from the measurements with the spikes removed. The method was validated by comparing the results with MPD measurements obtained with a Circular Texture Meter (CTMeter) that was chosen as the control device. Although this first method was able to successfully remove the spikes, it has the drawback that it depends on manual modeling of the distribution of the wavelet coefficients to correctly define an appropriate threshold. The next step of this dissertation proposes an enhanced to the spike removal methodology for macrotexture measurements taken with high-speed laser devices. This denoising methodology uses an algorithm that defines the distribution of texture measurements by using the family of Generalized Gaussian Distributions (GGD), along with the False Discovery Rate (FDR) method that controls the proportion of wrongly identified spikes among all identified spikes. The FDR control allows for an adaptive threshold selection that differentiates between valid measurements and spikes. The validation of the method showed that the MPD results obtained with denoised dynamic measurements are comparable to MPD results from the control devices. This second method is included as a crucial step in the last stage of this dissertation as explained following. The last part of the dissertation presents an enhanced macrotexture characterization index based on the Effective Area for Water Evacuation (EAWE), which: (1) Estimates the potential of the pavement to drain water and (2) Correlates better with two pavement… Advisors/Committee Members: Flintsch, Gerardo W.

More than one million people are killed annually around the world as a result of traffic accidents. In Brazil, this epidemic costs the public coffers 56 billion a year. More than half of the fatal accidents in Rio Grande do Sul occur in night or dawn periods, but less than a third of the displacements occur at these times. Considering these affirmatives, road safety devices operating in periods with no sunlight should be effective in order to provide safety to road users. The main devices acting in these periods are road demarcations and retroreflective signs. Therefore, the objective of this research is to follow the retroreflective indices of the road demarcations applied on a section of BR-287, located in the city of Santa Maria - RS. The surface of the pavement is equipped with MRAF. The work consisted in the monitoring of retroreflectivity and surface texture of the stretch during two years. The results showed that these demarcations applied on this type of surface tend to have lower retroreflectivity values than the others, but with the same degradation rate, 0.01% per day. The retroreflectivity values tend to fall more rapidly in the first days of life, presenting a peak near the 30 days and, after that, fall again smoothly until they present a horizontal asymptote. No influence of the precipitation on the retroreflectivity values was found in this study, since in the study section there was little request of the lines in front of the friction with the vehicle tires. The measurement direction does not interfere in the results of retroreflectivity in places where the paint speed was low. The white demarcations present, on average, 30% higher retroreflectivity values compared to the yellow demarcations. The demarcations showed 50% lower retroreflectivity values when measured with geometry equipment equal to 30m when compared to values measured with 15m geometry. When wet, demarcations lose about 80% of their retroreflective capacity. The periodic cleaning of the demarcations was beneficial for the retroreflectivity indices. It was evidenced that the macrotexture of the pavement is directly connected with the retroreflectivity of the demarcations, flatter classes have higher retroreflectivity values. The microtexture of the demarcations also had an influence on the retroreflective properties. In addition, the study determined the optimal rate of application of glass microspheres 325g / m² painted, different from what is today in SICRO 250g / m².

Mais de um milhão de pessoas perdem a vida anualmente ao redor do mundo em decorrência de acidentes de trânsito. No Brasil, essa epidemia custa aos cofres públicos 56 bilhões anuais. Mais da metade dos acidentes fatais no Rio Grande do Sul ocorrem em períodos da noite ou madrugada, porém, menos de um terço dos deslocamentos ocorrem nestes horários. Considerando tais afirmativas, os dispositivos de segurança viária atuantes em períodos com ausência da luz solar devem ser efetivos, a fim de proporcionar segurança aos usuários das rodovias.

▼ This dissertation is compiled of the findings of several phases of a detailed research study that was aimed at investigating the Skid Resistance phenomenon. In the first phase of the dissertation research a study was performed to evaluate the different factors that influence frictional measurements obtained using the Dynamic Friction Tester (DFT). A temperature calibration factor that would account for temperature effects on DFT readings and IFI computations was developed. In addition, other variables that also affect the friction measurements obtained using the DFT are identified. In the next phase of the dissertation research the effect of pavement roughness on the Skid Resistance was investigated. The variation of the normal load and its nonlinear relation to SN was used to explain lower SN values measured on relatively rougher surfaces. The feasibility of using the International Roughness Index (IRI) and the Dynamic Load Coefficient (DLC) as predictors of the reduction in SN due to pavement roughness was also investigated. In the final phase of the dissertation research an in-depth investigation was carried out to better understand the principles underlying the concept of the International Friction Index (IFI), and specifically the role played by the Speed Constant ( Sp) parameter in the IFI computations. The parameter Sp dictates the speed variation of the wet friction measurements taken on a given pavement surface. The results of the current investigation suggest the revision of the procedure for computation of the Sp parameter to incorporate device specific properties. Furthermore, the incorporation of vehicle characteristics in the Sp parameter computations would help address a well known deficiency of the IFI, which is the inconsistent FR60 (predicted friction at 60 km/h) obtained from the friction values measured at two different slip speeds on the same surface. This study also showed that the modification of the Sp parameter reduces significantly the slip speed dependency of the device calibration parameters A and B. Finally, a modified IFI procedure that incorporates device specific slip conditions is presented. The modified IFI procedure showed consistently better predictive capability than the conventional ASTM procedure on all the different devices considered in this study.

O gerenciamento de uma malha rodoviária engloba avaliações constantes das condições estruturais e, principalmente, funcionais. Assim sendo, uma forma de coleta automatizada, realizada em velocidades de tráfego, em que a influência humana possa ser desconsiderada, está em desenvolvimento na engenharia rodoviária brasileira, assim como é visto internacionalmente. O presente trabalho tem como objetivo a contribuição para o processo de avaliação funcional de pavimentos através do estudo sobre a aplicabilidade do processo de inventário funcional de pavimentos rígidos com o emprego do equipamento Pavement Scanner. Para tanto, após a revisão bibliográfica sobre a sistemática de inventário de pavimentos rígidos e também sobre o equipamento Pavement Scanner, seções testes foram definidas e avaliadas de acordo com o método tradicional de levantamento da superfície do pavimento (ICP - DNIT 062/PRO, DNIT 060/PRO), o método volumétrico tradicional de mancha de areia para avaliação de macrotextura (ASTM E 965/96), através de imageamento com análise de imagens obtidas no trecho e sob a utilização do equipamento Pavement Scanner. Com os resultados foi realizada uma análise estatística destas técnicas utilizadas, demonstrando a viabilidade de utilização do equipamento e do procedimento de análise adotado.

The management of a road network encompasses constant assessments of structural conditions and, above all, functional conditions. Thus, a form of automated survey, carried out at traffic speeds, in which human influence can be unconsidered, is under development in Brazilian road engineering, as it is seen internationally. This present work aims to contribute to the process of functional assessment of pavements through the study of applicability of the functional inventory process of rigid pavements with the use of Pavement Scanner equipment. In order to do so, after the literature review of rigid pavement inventory and Pavement Scanner equipment, test sections were defined and evaluated according to the traditional method of surface survey (ICP - DNIT 062 / PRO, DNIT 060 / PRO), the traditional sand patch volumetric method for the evaluation of macrotexture (ASTM E 965/96), through imaging analysis from the test sections and under the use of Pavement Scanner equipment. With the results, a statistical analysis of these techniques were performed, demonstrating the feasibility of using the equipment and the analysis procedure adopted.

▼ This work evaluates the pavement surface condition and detects the pavement subsurface delamination through vehicle noise collected by microphones mounted underneath a moving vehicle. Such measurements will include tire-generated sound, which carries much information about the road condition, as well as noise generated by the environment and vehicle. A careful frequency analysis of the vehicle noise is carried out to localize the frequency range for surface characteristics and subsurface delamination respectively. The Principal Component Analysis (PCA) method is applied to differentiate important information about the road condition from noisy data contributions collected while the vehicle is moving. The analysis begins with acoustic pressure measurements made over constant and known road conditions. Fourier transforms are taken over various time windows and a PCA is performed over the resulting vectors, yielding a set of principal component vectors for the road condition. The condition of each road section is characterized by a set of principal component vectors. Pavement macrotexture Mean Texture Depth (MTD) is predicted from the principal component vector and then projected to the overall pavement condition index (PCI) as well as the pavement friction and uniformity evaluation. Pavement subsurface delamination is also detected from the principal component vector. The significant accomplishments of this study are as follows: (1) localize the frequency ranges of vehicle noise related to pavement surface and subsurface features respectively; (2) demonstrate the potential for PCA to reduce noise and illustrate the procedure to apply PCA in frequency domain for noise filtering; (3) find the relationship between MTD, sound pressure and driving speed; (4) optimize the microphone placement for data collection for the MTD prediction; (5) develop a calibration-free method for the MTD prediction with an error of 16%; (6) use the predicted Equivalent MTD found by the PCA Energy Method to explore pavement friction prediction, construction non-segregation evaluation, and the contribution to PCI prediction from the acoustic aspect; (7) differentiate the stiffness of the top layer pavement within 10 cm of surface from tire/road noise, and (8) detect the subsurface delamination from the shift of frequency in peak sound pressure level.

▼ Superhydrophobic surfaces execute self-cleaning, anti-icing, and modifying heat transfer in many technological and industrial applications. In quest of maximizing water repellency, modification of droplet dynamics and subsequent reduction of contact time have been achieved by incorporating macrotexture on the superhydrophobic surfaces. However, the dynamics of low temperature water, and other viscous liquid droplets impacting anti-wetting surfaces with macrotextures is not well explored. In this thesis, we study the effect of viscosity on the bouncing dynamics of liquid droplets impacting macrotextured superamphiphobic surfaces using various glycerol-water mixtures as model liquids at different impacting conditions. Macrotextured surface are made by using an anti-wetting spray coating along with a tinned-copper wire as ridge on the silicon substrate. The complexity of viscous dissipation along the macrotexture and on the superamphiphobic surface is studied experimentally and then a new model is proposed for understanding when the macrotexture can induce maximum repellency of the viscous liquids on the superamphiphobic surfaces. A universal model for predicting minimum impact velocity for splitting is developed considering the droplet viscosity, velocity, volume, and other important parameters along with the surface characteristics and the macrotexture size. This enables engineering of surfaces for repelling droplets of viscous liquids such as freezing rain or inks during inkjet printing. Moreover, we studied the potentiality of superhydrophobic highly porous carbon nanotube (CNT) micropillars coated by the ultrathin, conformal, and low-surface-energy layer of poly (1H,1H,2H,2H-perfluorodecyl acrylate) (pPFDA) surfaces in condensation and freezing conditions (at high humidity). Droplet impact dynamics, condensate characteristics and freezing time delays are investigated on the CNT micropillars with various geometry along with the CNT forest and other commercially available anti-wetting coatings. Different wetting states (Cassie and Wenzel) of the coalesced condensate drops are observed on CNT micropillars with different solid area fractions and heights. In the low temperature and humid surroundings, CNT micropillars with the favorable topological configuration demonstrate complete droplet bouncing, significant freezing delays and considerable durability during several icing/de-icing cycles. This study provides understanding on the preferable geometry of the highly porous CNT micropillars for retaining hydrophobicity and preventing ice formation in the low temperature environments.

Esta pesquisa foi baseada em um projeto de Stone Matrix Asphalt - SMA na faixa 0/8S com asfalto CAP 20, feito para a execução de revestimento delgado em trecho experimental na Rodovia Presidente Dutra, ligando São Paulo ao Rio de Janeiro. A ocorrência de alguns defeitos neste trecho experimental motivou o estudo de misturas SMA 0/8S alternativas empregando dois asfaltos convencionais: CAP 20 e CAP 50/60, e dois modificados por polímeros: um com 3,0% de SBS e outro com 6,5% de SBS. Foram realizados ensaios laboratoriais para a verificação da dosagem das misturas asfálticas e determinação de propriedades mecânicas em laboratório por meio de ensaios de deformação permanente em trilha de roda, de resistência à tração por compressão diametral e de módulo de resiliência. Observou-se que o uso de asfalto modificado por polímero e do asfalto convencional CAP 50/60 acarreta uma redução significativa de afundamentos em trilha de roda. O módulo de resiliência a 25°C também apresenta redução de valor nas amostras com asfalto modificado por polímero e com CAP 50/60, em comparação com o convencional CAP 20. A resistência à tração sofre pouca variação quando se comparam os asfaltos empregados, considerando-se ensaios realizados na mesma temperatura. Foram feitos ensaios em campo para a avaliação funcional e de aderência no trecho experimental da Rodovia Presidente Dutra, tendo sido realizados monitoramentos logo após a execução do trecho e decorridos 2 anos e 7 meses de operação. Os resultados demonstraram que o revestimento do trecho experimental apresenta atualmente poucos defeitos de superfície, com fechamento da macrotextura nas trilhas de roda e pequena diminuição do conforto ao rolamento.

This research was based on a Stone Matrix Asphalt SMA in the band 0/8S design made with asphalt binder AC 20, used as a thin wearing course of a test section on the Presidente Dutra Highway, that connects São Paulo to Rio de Janeiro. The occurrence of some distresses in the test section motivated the study of alternative SMA 0/8S mixtures using two conventional asphalt binders: AC 20 and AC 50/60, and two modified by polymer: one with 3.0% of SBS and other with 6.5% of SBS. Laboratory tests were conducted to verify the mix design and to determine their mechanical behavior such as the resistance against rutting, the indirect tensile strength and the resilient modulus. It was observed that the use of SBS polymer modified binders and asphalt binder AC 50/60 causes a significant reduction of rutting. The resilient modulus at 25°C also presents a reduction in the samples with SBS polymer modified binders and AC 50/60 in comparison with AC 20. The indirect tensile strength suffers little variation across the different types of asphalt binders, tested at the same temperature. Field tests related to functional evaluation and skid-resistance of the test section were carried out. The test section was monitored immediately following the construction and after 2 years and 7 months of continuous use. The results showed that the wearing coarse…
