Abstract
A rubber-modified asphalt composition prepared by blending a terpene resin with the reaction product of (1) a polymerizable aromatic monomer, a rubbery polymer and a bituminous material such as asphalt. The modified asphalt composition of the invention can thus be used in the treatment of glass fibers as well as in road-paving applications, roofing applications and the like.
Claims16
A chemically modified asphalt composition comprising (1) an asphalt which has been reacted with a polymerizable vinyl aromatic monomer and a rubbery polymer and (2) a terpene resin, said terpene resin being present in an amount sufficient to reduce the viscosity of said reacted asphalt.
