The Asphalt Pavement Technology Program is an integrated, national effort to improve the long‐term performance and cost effectiveness of asphalt pavements. Managed by the Federal Highway Administration through partnerships with State highway agencies, Industry and academia the program’s primary goals are to reduce congestion, improve safety, and foster technology innovation. The program was est...

ii To my family, friends and professors who helped me throughout this experience iii ACKNOWLEDGEMENTS This research project was made possible with the help of many supporting people throughout the process. I wish to express my gratitude firstly to my supervising professor, Dr. Hosin " David " Lee for the support and advice needed to start and finish this project. I would also like to thank the ...

Conductive asphalt concrete with high thermal conductivity has been proposed to improve the solar energy collection and snow melting efficiencies of asphalt solar collector (ASC). This paper aims to provide some insight into choosing the basic materials for preparation of conductive asphalt concrete, as well as determining the evolution of thermal characteristics affected by environmental facto...

The public, industry, and governments have become increasingly interested in green design and sustainable development. Construction activities affect the environment significantly, so environmental issues should be considered seriously. Thousands of miles of roads are paved every year with asphalt and steel-reinforced concrete. What are the environmental effects of the two materials? If asphalt...

Asphalt paving is a specific type of construction work: the machines and materials constantly move while the asphalt mixture constantly cools down. The machine operators do have a clear goal – to provide an equally distributed and uniformly compacted asphalt layer in time-restricted conditions. But what does it mean in particular? In reality, the asphalt should be compacted to a certain degree ...

With the rapid global expansion of road networks, asphalt industry faces several environmental challenges, such as material shortages, concerns, escalating costs, demand for eco-friendly materials, and implementation “Net Zero” policies. Given these challenges recognizing need to explore new solutions, this research evaluated binder samples incorporating Warm Mix Asphalt (WMA) Reclaimed Pavemen...

This study used a cradle-to-cradle Life Cycle Assessment (LCA) approach to evaluate the environmental potentials of urban pavements. For this purpose, road network City Münster (Germany) was selected as case study, and comprehensive data for several phases were collected. The entire is composed flexible pavements designed according specific traffic loads consists main roads (MRs), access (MARs)...

In order to improve the sustainability of road pavements, transportation agencies should consider designing pavements with recycled materials such as reclaimed epoxy asphalt pavement. Epoxy has recently attracted significant attention from pavement community a superior-performing binder that can help achieve long-lasting pavements. The recyclability proven long-life material, asphalt, now becom...

A new composite membrane system, Geo-SealTM, has been developed that offers exceptional chemical resistance for use as a vapor barrier at brownfield sites. Data generated in controlled laboratory conditions indicate the composite membrane to have < 0.2X the volatile organic compound partitioning when compared to spray applied latex/asphalt vapor barriers. More importantly, data generated under ...

This paper presents a computational modeling study of the microstructural influence on damage behavior of asphalt materials. Computer generated asphalt samples were created for numerical simulation in indirect tension and compression testing geometries. Our previously developed micromechanical finite element model was used in the simulations. This model uses a special purpose finite element tha...
