Abstract
A rubber-modified asphalt composition prepared by reacting asphalt with a rubbery polymer, a polymerizable vinyl aromatic monomer and a polymerizable vinyl aromatic monomer in which the vinyl group is substituted whereby the chemical integration of the rubbery polymer with the asphalt is accelerated by the use of a combination of the polymerizable vinyl aromatic monomer and the substituted vinyl aromatic monomer.
