▎ 摘　　要

NOVELTY - The method involves selecting matrix asphalt. An asphalt component separation test is performed to separate the matrix asphalt into asphaltene, colloid, aromatic and saturated four components. Weight ratio of each component is calculated. Elements of the asphalt four components are determined. Functional distribution and relative molecular weight are determined. A molecular model number of each component is calculated in an asphalt molecular model. Anti-cracking performance evaluation value of graphene modified asphalt is calculated corresponding to doping amount. USE - Method for evaluating anti-cracking performance of graphene modified asphalt. ADVANTAGE - The method can scientifically and intuitively characterizing influence of graphene doping to graphene modified asphalt anti-cracking performance through molecular dynamics simulation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene modified asphalt.
