Abstract: This paper presents the results of a comprehensive laboratory testing program that was conducted to develop a performance-based approach to design asphalt-treated base-course mixtures. Eight asphalt-treated base-course ...

Abstract: A series of triaxial compression tests and cyclic triaxial tests were conducted on unreinforced and geogrid reinforced crushed limestone samples to investigate the effects of the geogrid type, location, and number of layers ...

Abstract: In recent years, a new group of technologies has been introduced in the United States that allow producing asphalt mixtures at temperatures 30 to 100°F (16.7–55.6°C) lower than what is used in traditional hot-mix asphalt ...

Abstract: This study examined the effect of three extraction solvents [trichloroethylene (TCE), toluene, and nPB] on the rheological properties of recovered asphalt binders when used with four binders of different performance grades ...

Abstract: This study examines the accuracy of dynamic modulus, |E*|, predictions made by the Mechanistic-Empirical Pavement Design Guide (MEPDG) for short-term and long-term aged hot mix asphalt (HMA) and foamed warm mix asphalt ...

Abstract: This study involves using warm-mix additives (WMA) to produce binders that can aid compaction at low temperatures during cold weather paving. For this purpose, a performance grade (PG) 58-28 asphalt binder was chosen as a ...
