Abstract
A chemically modified asphalt prepared by reacting an asphalt with a polymerizable vinyl monomer (e.g., styrene) and a rubbery polymer including reclaimed rubber (either natural or synthetic) whereby the rubbery polymer is chemically integrated with the asphalt. 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.
