▎ 摘　　要

NOVELTY - Graphene-modified asphalt comprises 100-140 pts. wt. asphalt, and 1-20 pts. wt. modifier; the modifier is modified graphene, the raw materials for preparing the modifier includes graphene, styrene-butadiene-styrene block copolymer, polyurethane, rubber, compatibilizer, coupling agent, sulfur and accelerator. USE - Used as graphene-modified asphalt. ADVANTAGE - The graphene-modified asphalt: has strong aging resistance, fatigue resistance and hydrophobicity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene-modified asphalt comprising preheating and dispersing the modifier to obtain a preheated and dispersed modifier; heating asphalt, mixing obtained molten asphalt with preheated and dispersed modifier to obtain a premix; subjecting premix to shearing and heat preservation in sequence to obtain the graphene-modified asphalt.
