ABSTRACT:
A rubber tire recycling process comprises the steps of granulating rubber tires to form coarse rubber crumbs, mixing the coarse rubber crumbs with coarse siliceous grains to form a closely packed mixture of coarse particles that are roughly commensurate in size, thoroughly wetting the surfaces of the coarse particles with a polymerizable liquid binder to provide a viscous slurry, casting the slurry into a sheet-like configuration, and curing the sheet-like configuration under sufficient heat and for a sufficient time to provide an environmentally compatible sheet-like product, e.g. a paver or tile for driveways, or a shingle for roof tops, that is characterized by excellent weather, wear and chemical resistance. The surface characteristics of the coarse particles of vulcanized rubber and crystalline grains are critical to the present invention.
