Abstract:
In a first aspect, bituminous asphalt binder materials which are modified by the addition of crumb rubber or ground tire rubber are described. In a second aspect, the present invention is directed to methods of producing a modified asphalt binder containing crumb rubber or ground tire rubber. The modified asphalt binders comprise neat asphalt, crumb rubber, one or more synthetic polymers, and one or more acids. The crumb rubber may be obtained from recycled truck and/or automobile tires.
