Abstract:

Most of U.S. southeastern states experience both hot and wet summer weather. Extremely high relative humidity and a ; low dew point maintain a continuous fi lm of water on Gulf Coast roads during the night and early morning hours. Should ; the laboratory protocols for aging asphalt binders consider the vapors of water as components of the aging atmosphere ; as well as air (oxygen) exposure? It was the goal of the present investigation to address the potential infl uence of water ; on the aging of road pavements containing polymer modifi ed asphalt cements (PMAC).
