Abstract
A method of forming an asphalt paving material containing recycled plastics. A first step involves forming recycled plastics into plastic particles. A second step involves dry mixing and heating aggregate and sand. A third step involves dry mixing untreated plastic particles with the aggregate and sand, while continuing heating until the mixture of plastic particles, aggregate and sand reaches a temperature range provided in accepted road building specifications for heating aggregate. A fourth step involves adding liquid asphalt to the mixture of plastic particles, aggregate and sand.
Claims (13)
