▎ 摘　　要

NOVELTY - A modified asphalt comprises 1-10 wt.% sulfur-doped graphene, 1-5 wt.% accelerator, 15-30 wt.% waste rubber powder and remainder of matrix asphalt. The accelerator is chosen from 2-thiocyanobenzothiazole, 2-thiol-based benzothiazole zinc salt, dibenzothiazole disulfide, 4,4'-disulfide dimorpholine, diphenylguanidine, tetramethylthiuram disulfide and dimercaptobenzothiophene. USE - Modified asphalt (claimed). ADVANTAGE - The modified asphalt has excellent physical properties and structural properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of modified asphalt.
