Estimating the term…
An asphalt composition comprising 0.1 to 8 wt.-% based on the total weight of the composition of an Isocyanate as thermosetting reactive compound and 0.1 to 8 wt.-% based on the total weight of the composition of a polymer selected from the group consisting 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 (FRA).
An asphalt composition comprising 0.1 to 8 wt.-% based on the total weight of the composition of an Isocyanate, wherein the isocyanate is polymeric MDI, wherein the polymeric MDI has a viscosity in the range of from 10 to 5000 cps/mPas at 25° C., and 0.1 to 8 wt.-% based on the total weight of the composition of a polymer selected from the group consisting of styrene/butadiene/styrene copolymer (SBS), and polyphosphoric acid (PPA).
