ABSTRACT:
The present invention provides an improved polymer additive which may be used to increase the high temperature viscosity of an asphalt, without deleteriously affecting the low-temperature viscosity of the asphalt. The polymer additive may also be used to improve the stiffness of certain asphalts. The polymer additive is produced from readily available polymer blends by a thermal process. The invention additionally provides an improved polymer modified asphalt. In its preferred embodiments, the invention also provides an environmentally acceptable method for recycle of post consumer carpet and bottles.
