摘要

A building or road construction material, and method for its formation, which comprises (1) mineral components such as sand, gravel, diminuted glass, etc., (2) polymeric components such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc., and (3) a hydrocarbon-containing component such as tar pitch, bituminous products, petroleum coke, etc. According to the method of the invention the mineral component is first heated to a temperature of at least 180 DEG C and then mixed with the polymeric component in diminutive form, and then to this resulting mixture is added the hydrocarbon component. The final mixture is then allowed to cool to form the desired product.
