Abstract：Plastic deformation of asphalt mixture is an important component of asphalt pavement durability, which is affected by many factor. In this study, three kinds of composite modified asphalt were used to form different composite modified asphalt mixtures, whose plastic deformations were analyzed under different influencing factors (Binder, aggregate gradation, loading times, ageing time and test temperature). The research results show that the ability to resist plastic deformation of 4%SBS/15% rubber powder asphalt mixture with AC-20 is the best, and the 4%SBR/15% rubber powder asphalt mixture with AC-13 is the poorest. The various factors influencing plastic deformation of asphalt mixture were evaluated by using grey relational theory.
