ABSTRACT:
An improved asphalt composition for pavement and a method for producing the same is characterized by mixing peroxide with crumb rubber to modify the crumb rubber so that mixes more evenly with the asphalt when added thereto. A compatibilizer/polymer is also added to the asphalt. The resulting composition is homogeneous and demonstrates improved settling and rheological properties at high and low temperatures.
