ABSTRACT:
A process for preparing an incorporated asphalt composition includes mixing ground tire rubber with distillation tower bottoms to form a wetted mixture of the ground tire rubber with the distillation tower bottoms, bombarding the wetted mixture of ground tire rubber and distillation tower bottoms with air at a temperature of about 350.degree.-485.degree. F. at about 6-15 psi pressure until the mixture is completely incorporated, and recovering the incorporated asphalt composition. The homogenized asphalt product is a two-member composition of distillation tower bottoms having ground tire rubber incorporated therein.
