ABSTRACT:
An improved method for treating crumb rubber particles for use in asphalt compositions is characterized by activating the particles to enhance the rheological properties thereof. A slurry of crumb rubber particles is formed by adding water thereto. The slurry is heated to a temperature of 85-90.degree. C. to release excess oils and chemicals from the particles into the slurry. The slurry is dried to produce a fine mesh rubber product with enhanced rheological properties.
