Abstract
A method and system for generating a rapid digestion process (“RDP”) product are described. The method includes receiving a bitumen compound and first heating the bitumen compound to 320° F. to 420° F. The method then proceeds to add tire rubber to the bitumen compound. The bitumen compound and the tire rubber are mixed for 5 minutes to 360 minutes during a second heating to 525° F. to 700° F. Further, sulfur is added to the mixture of tire rubber and bitumen compound. These steps generate the RDP product. The RDP product is then cooled for transfer to a storage vessel.
Claims10
A method for generating a modified dissolved tire rubber bitumen compound comprising:
- receiving bitumen compound;
- heating the bitumen compound to between 320° F. to 420° F.;
- adding a tire rubber to the bitumen compound;
- mixing the bitumen compound and the tire rubber for 5 minutes to 360 minutes, wherein the bitumen compound and the tire rubber are heated submitted to a second heating of between 525° F. to 700° F. during mixing;
- adding sulfur to the mixture of the tire rubber and the bitumen compound;
- and
- cooling the resulting modified dissolved tire rubber bitumen compound.
