▎ 摘　　要

NOVELTY - A graphene composite rubber asphalt modifier comprises 0.00005-0.01 pt. wt., preferably 0.003 pt. wt. graphene powder, 3-23 pts. wt., preferably 13 pts. wt. dispersion medium, 78-92 pts. wt., preferably 85 pts. wt. rubber powder and 0.05-6 pts. wt., preferably 2.5 pts. wt. additive. USE - Graphene composite rubber asphalt modifier used for road construction. ADVANTAGE - The graphene composite rubber asphalt modifier has improved compatibility and stability provided by rubber powder, and excellent bonding performance and high and low-temperature stability, reduces the temperature of the road surface, and prolongs the service life of the road. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene composite rubber asphalt modifier, which involves (1) mixing graphene powder and dispersion medium, mechanically stirring, and dispersing at high speed to obtain graphene dispersion, and (2) mixing the graphene dispersion with rubber powder and additive.
