ABSTRACT:
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) hydrocarbon-containing component such as tar pitch, bituminous products, petroleum coke, etc. combined in a special proportion to produce materials with improved properties such as a particularly large Marshall stability, a large compression strength and an excellent fluting, tracking and crack resistance. According to the method, the mineral component is first heated to a temperature of at least 180.degree. C and then mixed with the polymeric component in diminutive form, in which the percentage by weight of polymeric components amounts to at most 100 percent, calculated on the amount by weight of the hydrocarbon component, and then to this resulting mixture is added the hydrocarbon component, provided that, if a bituminuous product is used as the hydrocarbon component, the percentage by weight of the polymeric component should in addition amount to at least 20 percent by weight, calculated on the amount of bitumen. The final mixture is then allowed to cool to form the desired product.
