Abstract

A method and system for generating a tire rubber asphalt compound is described. The method includes receiving an asphalt compound and heating the asphalt compound to approximately 320° F. to 420° F. The method then proceeds to add tire rubber to the asphalt compound. The asphalt compound and the scrap tire rubber are mixed for approximately 60 minutes to 360 minutes during heating to approximately 525° F. to 700° F. to generate the tire rubber asphalt compound. The tire rubber asphalt compound is then cooled.

Claims (45)

1. A method for generating a tire asphalt compound comprising:

receiving an asphalt compound;

heating the asphalt compound to approximately 320° F. to 420° F.;

adding a tire rubber to the asphalt compound;

generating the tire rubber asphalt compound by mixing the asphalt compound and the tire rubber for 60 minutes to 360 minutes, wherein the asphalt compound and the tire rubber are heated to approximately 525° F. to 700° F. during mixing, and wherein there is little or no oxidation of the asphalt compound, the tire rubber, and the tire rubber asphalt compound; and

cooling the tire rubber asphalt compound.

2. The method of claim 1 further comprising applying a neutral gas when generating the tire rubber asphalt compound.

3. The method of claim 1 further comprising cooling the tire rubber asphalt compound to 500° F. to 350° F.

4. The method of claim 1 further including separating the tire rubber asphalt compound from a metallic alloy, wherein the tire rubber includes a metallic alloy.

5. The method of claim 1 wherein the asphalt compound has a penetration of 0 dmm to 200 dmm.

6. The method of claim 1 wherein the asphalt compound is received by a wetting tank, the tire rubber is added to the asphalt compound in the wetting tank, and the wetting tank is heated to approximately 320° F. to 420° F.; and

the tire rubber asphalt compound is generated in a reaction vessel heated to approximately 525° F. to 700° F.

7. The method of claim 1 wherein the asphalt compound and the tire rubber are received by a reaction vessel that is heated; and

the tire rubber asphalt compound is generated in the reaction vessel.

8. A method for generating a tire rubber medium comprising:

receiving an oil compound;

heating the oil compound to approximately 320° F. to 420° F.;

adding a tire rubber to the oil compound;

generating the tire rubber medium by mixing the oil compound and the tire rubber for 60 minutes to 360 minutes, wherein the oil compound and the tire rubber are heated to approximately 525° F. to 700° F. during mixing, and wherein there is little or no oxidation of the oil compound, the tire rubber, and the tire rubber medium; and

cooling the tire rubber medium.

9. The method of claim 8 further comprising applying a neutral gas when generating the tire rubber medium.

10. The method of claim 8 further comprising cooling the tire rubber medium to 500° F. to 350° F.

11. The method of claim 8 further including separating the tire rubber medium from a metallic alloy, wherein the tire rubber includes a metallic alloy.

12. The method of claim 8 wherein the oil compound and the tire rubber are received by a wetting tank that is heated to approximately 320° F. to 420° F.; and

the tire rubber medium is generated in a reaction vessel heated to approximately 525° F. to 700° F.

13. The method of claim 8 wherein the oil compound and the tire rubber are received by a reaction vessel that is heated to approximately 320° F. to 420° F.; and

the tire rubber medium is generated in the reaction vessel heated to approximately 525° F. to 700° F.

14. A system for generating a tire rubber asphalt compound, the system comprising:

a wetting tank that receives an asphalt compound;

a tire rubber that is received by the wetting tank;

wherein the tire rubber and the asphalt compound are heated to 320° F. to 420° F. in the wetting tank to generate a wetting tank mixture;

a reaction vessel that receives the wetting tank mixture and heats the wetting tank mixture to approximately 525° F. to 700° F. for 60 minutes to 360 minutes to generate the tire rubber asphalt compound; and

wherein there is little or no oxidation in the reaction vessel.

15. The system of claim 14 wherein the reaction vessel cools the tire rubber asphalt compound to 500° F. to 350° F.

16. The system of claim 14 further comprising a separator that separates the tire rubber asphalt compound from a metallic alloy when the tire rubber includes a metallic alloy.

17. The system of claim 14 further comprising a neutral gas that is applied to the reaction vessel when generating the tire rubber asphalt compound.

18. A system for generating a tire rubber medium, the system comprising:

a reaction vessel that receives an oil compound;

a tire rubber that is received by the reaction vessel;

wherein the tire rubber and the oil compound are heated to 320° F. to 420° F. in the reaction vessel;

wherein the reaction vessel heats the tire rubber and the oil to approximately 525° F. to 700° F. for 60 minutes to 360 minutes to generate the tire rubber medium; and

wherein there is little or no oxidation in the reaction vessel.

19. The system of claim 18 wherein the reaction vessel cools the tire rubber medium to 500° F. to 350° F.

20. The system of claim 18 further comprising a separator that separates the tire rubber medium from a metallic alloy when the tire rubber includes a metallic alloy.

21. The method of claim 18 further comprising a neutral gas that is applied to the reaction vessel when generating the tire rubber medium.
