▎ 摘　　要

NOVELTY - Carboxy group-modified graphene oxide modified rubber asphalt mixed material comprises 5.34-10.23 pts. wt. petroleum asphalt, 0.42-1.21 pts. wt. tire rubber powder, 100 pts. wt. mineral stone and 1-2 pts. wt. carboxy modified graphene oxide. USE - Used as carboxy group-modified graphene oxide modified rubber asphalt mixed material. ADVANTAGE - The mixed material has excellent adhesion, storage stability, high temperature rut resistance and stability in construction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing carboxy group-modified graphene oxide modified rubber asphalt mixed material comprising (i) adding tire rubber powder into petroleum asphalt, and stirring to obtain rubber asphalt under first temperature, (ii) adding mineral stone and heating to second temperature, then adding carboxy modified graphene oxide, and then stirring to obtain mixed material, and (iii) adding rubber asphalt in the mixture, and then stirring to obtain final product.
