  • Process for the manufacture of particulate bituminized plastics material
    Patent number: 4797434
    Abstract: A process for the manufacture of particulate material, and particularly material for constructing a horse riding surface, involves mixing raw granulated plastics material, such as PVC from waste electric cable, with a bitumen emulsion and water in such a way that the granules are coated while significant agglomeration is avoided. The bitumen emulsion is preferably 40% cationic. The water may be added as a bulk at lower pressure and a small amount at high pressure which is moved around to promote mixing.
