Disclosed herein are rejuvenating compositions for asphalt applications. In one aspect, the rejuvenating composition comprises a polymerized oil having a polymeric distribution ranging from about 2 to about 80 wt % oligomer content and Hildebrand solubility ranging from about 6 to about 12. In another aspect, the rejuvenating composition comprises an oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100° C. to about 400° C. In yet another aspect, the rejuvenating composition comprises a modified oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100° C. to about 400° C.

Rejuvenating compositions for asphalt applications and methods of manufacturing the same

Embodiments of the present invention provide a method, comprising obtaining a lecithin-containing material, in some aspects derived from a crude refining stream, comprising 20-80 wt % acetone insoluble matter, 1-30 wt % free fatty acid, and less than 10 wt % water, adding a fatty acid or carboxylic source to the lecithin-containing material to obtain a lecithin fatty acid blend or lecithin carboxylic acid blend and incorporating the blend into asphalt or oil field applications.

Modified lecithin for asphalt applications

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.

Polymerized oils and methods of manufacturing the same

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to 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.

Described herein is a rejuvenated asphalt and a method of rejuvenating asphalt comprising mixing a rejuvenator, bitumen, and aggregate to obtain an asphalt mixture, wherein the rejuvenator is present in an amount ranging from about 0.1-40 wt % by weight of the bitumen, and wherein at least 35 wt % of the bitumen is derived from recycled asphalt content. The rejuvenated asphalt provides desirable performance.
