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 modified asphalt with incorporation measured by national standard test method. As affected adding on three indexes SBS was studied. Through analysis comparison experimental results, when parameter is 0.5%, performance graphene-SBS double-modified reaches optimum, which provides technical reference for diversification materials in alpine region Inner Mongolia.
