Abstract

Improved chemically modified asphalts are provided of the type which is the reaction product of asphalt, a vinyl aromatic monomer and a rubbery polymer. The improved compositions are capable of impregnating glass fiber bundles and have increased elastic recovery rates, increased viscosity stability, less tack and lower viscosity. Such improved compositions are obtained by employing a styrene-butadiene thermoplastic rubber copolymer as a coreactant with the asphalt and vinyl aromatic monomer.
