1. Latifi, Valbon. Evaluation of Pavement Performance Due to Overload Single Trip Permit Truck Traffic in Wisconsin.

Degree: MS, Engineering, 2014, University of Wisconsin – Milwaukee

This study researched the impacts of overweight permit vehicle traffic on flexible pavement performance in Wisconsin using field investigations and AASHTOWare MEPDG analyses. A database of Oversize/Overweight (OSOW) single trip permit truck records was analyzed and provided a network of Wisconsin corridors heavily trafficked by OSOW trucks. Four Wisconsin state trunk highways were selected for investigation due to a high level of OSOW truck traffic. The research included traffic counts to confirm the levels of truck traffic on these segments and to verify the high numbers of permits issued for OSOW trucks. Furthermore, the field work included the identification and quantification of pavement surface distresses by executing visual distress surveys allowing for the current pavement surface conditions to be rated using the pavement condition index. Comprehensive analyses were conducted to evaluate pavement performance due to normal traffic loads as well as normal traffic loads plus the OSOW truck traffic loads. The use of AASHTOWare MEPDG analyses presented a potential methodology for determining the proportion of pavement deterioration attributable to OSOW truck traffic. OSOW axle load distributions were integrated with baseline truck traffic levels to develop axle load spectra and other traffic input parameters for the MEPDG analysis. Visual distress surveys conducted at the selected segments of state trunk highways (STH) 140, 11, and 26 rated the pavement surface conditions as serious to poor, ranging from a PCI value of 13 on STH 140 to a PCI value of 52 on STH 11. Across these three segments, the maximum measured rutting depth along the outer wheel paths ranged from 0.82 in to 1.25 in, which exceeded WisDOT's threshold for acceptable rutting of 0.50 in. Only the segment of STH 23 exhibited a fair pavement surface condition due to PCI values of 63 and 66 in the two lanes, with a maximum rutting depth of 0.50 in. The generally poor pavement conditions across the sampled segments included significant pavement surface damage and distresses such as rutting, longitudinal and transverse cracking, significant fatigue cracking, and potholes. The predicted total pavement deterioration levels from the AASHTOWare MEPDG software were generally consistent with the levels of deterioration observed during the site investigations. However, the proportion of pavement damage and deterioration attributable to OSOW truck traffic was predicted to be fairly insignificant, with most distress indices showing relative increases of approximately 0.5% to 4%, with a few outliers. The addition of OSOW truck traffic to the baseline truck traffic volumes resulted in a small increase in the amount of pavement damage, rutting depths, and loss of ride quality compared with the predicted deterioration levels due to only the baseline traffic.

2. Varamini, Sina. Technical, Economic and Environmental Evaluation of Warm Mix Asphalt and Coloured Asphalt for Usage in Canada.

Degree: 2016, University of Waterloo

Transportation services play an important role in the Canadian economy, and social activities as well as Canada's competitiveness in the global economy. As one of the most valuable systems of transportation in Canada, 90 percent of all goods and services are transported via trucks over an extensive land area characterized by diverse landscapes and harsh environments. These unique characteristics of Canada, coupled with other challenges including an aging road network and highway infrastructure, limited finances, and environmental considerations provide great incentive to decision makers at federal, provincial/territorial, and municipal government levels to consider new and innovative ways to fund road transportation infrastructure. In an effort to evaluate two innovative pavement technologies applicable in both urban and rural areas, this research project is focused on (1) Coloured Hot Mix Asphalt (CHMA) and (2) Warm Mix Asphalt (WMA). The intent of the CHMA research study was to characterize the structural, functional, and environmental characteristics of the coloured asphalt design by analyzing laboratory and field performance. This research was focussed on providing innovative and sustainable solutions, which can be effectively used in Canada as means of ensuring durability and high performance throughout the material’s life cycle. To achieve the research objectives, materials collected during paving operations and materials produced under controlled laboratory conditions were systematically evaluated at CPATT to capture the impact of colouring pigment on the mixture’s strength. Results provided in this thesis suggest that pigmentation can adversely affect the performance and proper steps have to been taken to mitigate such effect: including using softer binder and lower Dust Proportion (DP) in the mixture. The state-of-the-art AASHTOWare Mechanistic-Empirical (M-E) Software was employed to complete the most accurate level of analysis, referred to as “Level 1”. ME analysis outputs were then used to develop prediction models for a design life of 50 years that can be used to establish Life Cycle Cost Analysis (LCCA). Based on LCCA analysis Bus Rapid Transit (BRT) lane structure surfaced with CHMA was found to be significantly more expensive to construct and maintain than a similar structure surfaced with HMA located in York Region. However, this cost difference is expected to decrease in near future as contractors are becoming more familiar with the mixture’s design and production techniques. This research further evaluated the performance of WMA technology by using different Performance-Graded Asphalt Cement (PGAC) sources modified with three types of WMA additives (Evotherm 3G, Rediset LQ, and SonneWarmix) in combination with two types of aggregate of pink granite and trap rock diabase. Results obtained in this comprehensive research were statistically analyzed to verify the significance of the results. All information collected from a combination of qualitative and quantitative laboratory test methods…
