Abstract
A chemically modified asphalt prepared by reacting an asphalt with a polymerizable vinyl monomer (e.g., styrene) and a rubbery polymer whereby the rubbery polymer is chemically integrated with the asphalt. The chemically modified asphalt can be, if desired, further cross linked by reaction with a cross linking agent such as a polycarboxylic acid, an organic isocyanate or an organic polyepoxide. The chemically modified asphalt compositions of the invention can be used in the treatment of glass fibers as well as in road paving applications and the like.
