Blends of Styrene Butadiene Copolymers with Ethylene Acrylate Copolymers and Ethylene Based Wax for Asphalt Modification

摘要

The present invention is a polymer-modified asphalt composition comprising an elastomeric polymer blend, a low molecular weight plastomer and an un-modified asphalt. Asphalt compositions of the present invention demonstrate improved elasticity and stiffness compared to conventional polymer-modified asphalt compositions.
