Abstract

A method of producing a road making material includes the steps of heating plastics and bitumen and mixing 5%-25% by weight of plastics with bitumen. The heated plastics/bitumen mixture is then mixed with aggregate to form a bitumous compound which may then be used to lay a road (pavement) surface. Alternatively, the heated plastics and bitumen is mixed directly with aggregate to form a bitumous compound. The plastics used is, preferably, waste plastics that is collected, cleaned and shredded, or the plastics may be pelletised or in the form of microbeads.
