▎ 摘　　要

NOVELTY - A chemically modified asphalt is prepared by modifying matrix asphalt with 5.5-15 %mass sulfur-doped graphene. USE - Chemically modified asphalt used as road building material. ADVANTAGE - The chemically modified asphalt has improved mechanical performance due to the addition of graphene, excellent high-temperature strength, improved low-temperature performance, and storage stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the chemically modified asphalt.
