▎ 摘　　要

NOVELTY - Rubber-plastic alloy asphalt modifier doped with graphene oxide/sulfur composite comprises e.g. waste plastic powder, waste rubber powder, graphene oxide/sulfur composite and auxiliary agent, where waste plastic powder is at least one of waste polyethylene plastic, waste polypropylene plastic, waste polycarbonate plastic, waste poly(methyl methacrylate) plastic, waste ethylene propylene plastic, waste phenol formaldehyde plastic, waste UP plastic, where waste rubber powder is at least one of waste styrene-butadiene rubber powder, waste natural rubber, waste butadiene rubber, waste isoprene rubber, waste butyl rubber, waste ethylene propylene rubber, waste silicone rubber and waste acrylate rubber, auxiliary agent is at least one of surfactant, plasticizer, styrene-butadiene styrene, styrene-butadiene rubber and ethylene-vinyl acetate, and surfactant is fluorocarbon active agent, where plasticizer is at least one of di-2-ethylhexyl phthalate, diisononyl phthalate and dibutyl phthalate. USE - The rubber-plastic alloy asphalt modifier doped with graphene oxide/sulfur composite is useful in asphalt mixture (claimed). ADVANTAGE - The rubber-plastic alloy asphalt modifier doped with graphene oxide/sulfur composite improves high temperature stability and fatigue life of asphalt without affecting low temperature stability of the asphalt.
