System and method for generating tire rubber asphalt
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.
1 . 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.
2 . The method of claim 1 further comprising applying a neutral gas when generating the modified dissolved tire rubber bitumen compound.
3 . The method of claim 1 further comprising cooling the modified dissolved tire rubber bitumen compound to 500° F. to 350° F.
4 . The method of claim 1 further including separating the modified dissolved tire rubber bitumen compound from a metallic alloy.
5 . The method of claim 1 wherein the bitumen compound has a penetration of 0 dmm to 200 dmm.
6 . The method of claim 1 wherein the bitumen compound is received by a reaction vessel, the tire rubber is added to the bitumen compound in the reaction vessel, and the reaction vessel is heated to between 320° F. to 420° F. to generate a first processed tire rubber and bitumen mixture; and
the modified dissolved tire rubber bitumen compound is generated in the reaction vessel by heating the first processed tire rubber and bitumen mixture to 525° F. to 700° F.
7 . The method of claim 1 further comprising cross-linking one of the tire rubber, the bitumen compound, the modified dissolved tire rubber bitumen compound, and any combination thereof with the added sulfur.
8 . The method of claim 1 wherein there is little or no oxidation of the bitumen compound, the tire rubber, and the modified dissolved tire rubber bitumen compound.
9 . The method of claim 1 further comprising:
generating volatile organic compounds (“VOCs”); and
cross-linking at least some of the VOCs with the added sulfur.
10 . The method of claim 1 further comprising applying a vacuum when generating the modified dissolved tire rubber bitumen compound.
