Abstract
Blends of two chemically modified asphalts are provided. The first is the product produced by reacting asphalt with a vinyl aromatic monomer and an amine of an acyclic unsaturated hydrocarbon, and the second is the product produced by reacting asphalt with a vinyl aromatic monomer and a rubbery polymer. These asphalts are useful for road construction, repair and maintenance as well as a coating for various substrates including cementitious substrates, glass and metal.
