ABSTRACT:
A rubber tire recycling process comprises the steps of granulating black rubber tire side walls and treads and granulating white rubber tire side walls to form coarse rubber crumbs, mixing the coarse rubber crumbs with fine clay particles to form a closely packed mixture, thoroughly wetting the surfaces of the coarse particles with a uncured EPDM rubber to provide a fluid, casting the fluid into a sheet-like configuration, and curing the sheet-like configuration under sufficient heat and for a sufficient time to provide an environmentally compatible paver for outdoor or indoor surfaces.
