▎ 摘　　要

NOVELTY - A graphene anti-rutting agent based modified asphalt is prepared using matrix asphalt and 1-7 wt.% graphene anti-rutting agent of matrix asphalt. The graphene anti-rutting agent comprises 10-50 pts. wt. polyolefin, 3-20 pts. wt. thermoplastic elastomer vinyl aromatic hydrocarbon-conjugated diene block copolymer, 10-30 pts. wt. graphene and 1-5 pts. wt. surfactant. USE - Graphene anti-rutting agent based modified asphalt (claimed). ADVANTAGE - The graphene anti-rutting agent based modified asphalt has excellent thermal storage stability and forms stable structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene based modified asphalt, which involves heating matrix asphalt to 155-165 degrees C, starting stirring device and adding graphene anti-rutting agent, and stirring for 10-15 minutes.
