摘要: AbstractSince its introduction, warm mix asphalt (WMA) has garnered a lot of attention and interest from the pavement industry as promising technology to replace conventional hot (HMA). Despite many benefits, including reducing emissions fuel usage, definitive answers on feasibility replacing HMA pavements with WMA are yet be answered. A major concern for is susceptibility moisture-induced damage. In this research study, mixtures prepared using three technologies- viz. Sasobit, Advera Foamer were evaluated their moisture permanent deformation in comparison an mixture. Tensile strength ratio (TSR) analyzer (APA) tests conducted these mixtures. Results show that moisture-based technologies (Advera Foamer) more susceptible However, rut depths APA, even moisture-conditioned specimens, indicated performance par HMA. Even ...
