Abstract

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

First claim

The invention claimed is:

1. A modified asphalt, comprising:
(a) about 60 to about 99.9 wt % asphalt binder; and
(b) about 0.1 to about 40 wt % of a blend of polymerized oil crosslinked with a sulfur-containing material and unmodified biorenewable oil, previously modified or functionalized oil, wherein the polymerized oil has a
i. a polymeric distribution having about 2 to about 80 wt % oligomer content;
ii. a polydispersity index ranging from about 1.30 to about 2.20; and
iii. sulfur content less than about 8 wt %.

2. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil material selected from the group consisting of palm oil, sunflower oil, corn oil, soybean oil, canola oil, rapeseed oil, linseed oil, tung oil, castor oil, tall oil, cottonseed oil, peanut oil, safflower oil, corn stillage oil, and combinations and crude streams thereof.

3. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil material selected from the group consisting of triacylglycerides, diacylglycerides, monoacylglycerides, and combinations thereof.

4. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil material comprising phospholipids.

5. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil material comprising an animal fat.

6. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil material comprising a vegetable oil.

7. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil comprising free fatty acids.

8. The modified asphalt of claim 1 , wherein the polymerized oil is derived from a starting oil comprising a partially hydrogenated oil.

9. The modified asphalt of claim 1 , wherein the polymerized oil has a sulfur content less than about 6 wt %.

10. The modified asphalt of claim 1 , wherein the polymerized oil has a sulfur content less than about 4 wt %.

11. The modified asphalt of claim 1 , wherein the polymerized oil has a sulfur content less than about 2 wt %.

12. The modified asphalt of claim 1 , wherein the modified asphalt binder is for paving applications.

13. The modified asphalt of claim 1 , wherein the modified asphalt is for roofing applications.

14. The modified asphalt of claim 1 , wherein the modified asphalt is for coating applications.

15. The modified asphalt of claim 1 , further comprising at least one from the group consisting of thermoplastic elastomeric and plastomeric polymers, polyphosphoric acid, anti-stripping additives, warm mix additives, emulsifier, and fibers.

16. The modified asphalt of claim 1 , further comprising reclaimed asphalt pavement millings.

17. The modified asphalt of claim 1 , wherein the unmodified biorenewable oil comprises palm oil, sunflower oil, corn oil, soybean oil, canola oil, rapeseed oil, linseed oil, tung oil, castor oil, tall oil, cottonseed oil, peanut oil, safflower oil, corn stillage oil, lecithin (phospholipids) and combinations and crude streams thereof.

18. The modified asphalt of claim 1 , wherein the sulfur-containing material comprises elemental sulfur.
