As a nanomaterial,graphene can affect the microstructure and macroscopic properties of the material,and make the material have electrical conductivity and thermal conductivity.The application effect of graphene and its related nanomaterials in asphalt and its mixture is remarkable.The characteristics of Gr(graphene),GO(graphene oxide)and GNPs(graphene nanosheets)in asphalt and its mixtures were reviewed,including high temperature performance,low temperature performance,aging performance,water stability,electrical conductivity and thermal conductivity.It is pointed out that Gr,GO and GNPs can improve the performance of asphalt and asphalt mixture,and improve the high temperature rutting resistance,aging resistance and water damage resistance.At the same time,due to the excellent thermal conductivity and electrical conductivity of Gr,GO and GNPs,the resistivity of asphalt and mixture can be reduced and the thermal conductivity can be improved.Graphene can play a better role in the construction of intelligent roads such as snow melting,ice melting and self-sensing pavement.
