Abstract
The present invention relates to rubber pellets made of an amount of vulcanized rubber and an amount of binder, with the vulcanized rubber preferably being discarded rubber. Additionally, the rubber pellets will preferably contain an amount of filler materials which are plastic or rubber or combinations thereof so that the preferred rubber pellet contains an amount of rubber equal to between about 50% and about 95% by weight of the rubber pellet, an amount of filler material equal to between about 0 and about 45% by weight of the rubber pellet, and an amount of binder equal to between about 5% and about 10% by weight of the rubber pellet. The rubber pellets are used in the formation of asphalt and are desirable because they provide necessary constituents to the asphalt and allow for elimination of equipment and separate ingredient addition steps from the asphalt formation process. The present invention is also desirable because it provides for a way to desirably dispose of waste rubber materials.
