摘要
Abstract
In order to investigate the effect of graphene on the anti segregation storage stability properties of rubber powder modified asphalt,graphene/rubber powder composite modified asphalt were prepared by adding different amounts of graphene when a rubber powder content was 20％of the matrix asphalt mass.Storage stability tests and dynamic viscoelasticity tests were conducted to comprehensively evaluate the composite modified asphalt.The ex-perimental results show that the optimal dosage of graphene is 1.0％of the mass of the matrix asphalt,and graphene with dosages of 0.5％and 1.0％can significantly improve the storage stability,high-temperature performance,and fatigue performance of rubber powder modified asphalt.However,when the graphene dosage increases to 1.5％,all the various properties of graphene/rubber powder composite modified asphalt decrease,so the graphene dosage should not be too high.This research result can provide a technical route and certain reference for the performance improvement and composite modification of rubber powder modified asphalt.关键词
