Study on properties of graphene-SBS double-modified asphalt

Abstract

In this paper, different proportions of graphene modifiers were used to double-modify the SBS-modified asphalt. The needle penetration, softening point, and ductility of modified asphalt with different proportions of graphene incorporation were measured by the national standard test method. As affected by adding different proportions of graphene on the three indexes of SBS modified asphalt was studied. Through the analysis and comparison of the experimental results, when the graphene parameter is 0.5%, the performance of graphene-SBS double-modified asphalt reaches the optimum, which provides technical reference for the diversification of modified asphalt materials in the alpine region of Inner Mongolia.
