Abstract: As the price of liquid asphalt continuously climbs, methods are being sought to decrease material costs without compromising material or pavement performance while having a positive influence on sustainability. One potential ...

Abstract: The objective of this study was to evaluate the use of crumb rubber (CR) from waste tires and engineered additives as a rejuvenator to high reclaimed asphalt pavement (RAP) content asphalt mixtures. Six asphalt mixtures ...

Abstract: The objective of this study was to compare the laboratory mechanistic properties of sulfur-modified warm-mix asphalt (WMA) with conventional asphalt mixtures. Three mixtures, two hot-mix asphalt (HMA) and one WMA, were ...

Abstract: This study aimed to evaluate the effect of laboratory aging levels on chemical and rheological properties of asphalt binder as well as fracture performance of asphalt mixture. Compacted asphalt mixtures were laboratory ...

Abstract: Past studies evaluated the mechanistic properties, economic benefits, and ecological impacts of sustainable asphalt mixtures. However, questions remain concerning the effects of these technologies on structural pavement ...

Abstract: The objective of this study was to quantify the levels and sources of variability in the measurements of volumetric and mechanical properties of dense-graded asphalt mixtures on the basis of existing test data from state ...

Abstract: The recycling of asphalt shingles in flexible pavements has received considerable interest in recent years for economic, environmental, and social reasons. The objective of this study was to evaluate the effects of adding ...
