Abstract
An improved asphalt composition is provided with the addition of a graft copolymer resin comprising a rubbery polymeric substrate and a rigid polymeric superstrate. A preferred graft copolymer resin is acrylonitrile-butadiene-styrene copolymer resin. Preferred compositions have increased temperature range performance and/or decreased penetration values as compared to the same compositions not containing the graft copolymer resins. The asphalt compositions may optionally contain a vulcanized rubber, preferably obtained from scrap tires.
