Abstract:

Warm mix asphalt (WMA) is a relatively new and emerging technology for the asphalt industry. ; It offers potential construction and environmental advantages over traditional hot mix asphalt ; (HMA). However, WMA must perform at least as well as HMA before it can be used to replace ; HMA. This study evaluates the performance of HMA and WMA mixes obtained from various ; field sites in the state of Washington. Different WMA technologies are examined in four separate ; projects; these technologies include Sasobit® and three water foaming technologies, Gencor® ; Green Machine Ultrafoam GX®, Aquablack™ and water injection. Performance tests are ; conducted on the cores and extracted binders to evaluate the resistance of HMA and WMA ; samples to fatigue and thermal cracking, rutting and moisture susceptibility. Additionally, the ; early-age field performance of WMA and HMA control pavements is compared.
