ABSTRACT:
Process and composition for styrene-ethylene-butylene-styrene (SEBS) block copolymer modified asphalt mixtures for use in roofing, sealing, paving, and waterproofing membranes. Powdered and pelletized SEBS is added to oxidized or unoxidized asphalt flux in high-shear processes, and is applied in hot and ambient uses such as cutbacks and emulsions, with or without added fillers, fibers, or other additives.
