1. A method for generating a solubilized tire rubber bitumen compound, the method comprising:
receiving a first bitumen compound;
receiving a tire rubber compound;
heating the first bitumen compound and the tire rubber compound to between 275° F. and 325° F. to generate a bitumen wetted tire rubber mixture;
adding a second bitumen compound to the bitumen wetted tire rubber mixture;
heating the second bitumen compound and the bitumen wetted tire rubber mixture to between 325° F. and 350° F. to generate a fully wetted tire rubber bitumen mixture;
heating the fully wetted tire rubber bitumen mixture to between 350° F. and 500° F. to generate a devulcanized fully wetted tire rubber bitumen mixture; and
heating the devulcanized fully wetted tire rubber bitumen mixture to between 500° F. and 700° F. to generate the solubilized tire rubber bitumen compound.
