Asphalt composition comprising mixture of isocyanate and polymer as performance additive

摘要

From 0.1 to 8% by weight, based on the total weight of the composition, of isocyanates as thermosetting reactive compounds; And 0.1 to 8% by weight, based on the total weight of the composition, of styrene/butadiene/styrene copolymer (SBS), styrene butadiene rubber (SBR), neoprene, polyethylene, low density polyethylene, oxidized high density. Polyethylene, polypropylene, oxidized high density polypropylene, maleated polypropylene, ethylene-butyl-acrylate-glycidyl-methacrylate terpolymer, ethyl vinyl acetate (EVA) and polyphosphoric acid (PPA) An asphalt composition comprising a polymer selected from the group is disclosed.
