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.

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.

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content ranging from 0.001 wt % to about 8 wt %.

A system for metering reinforcing aramid fibers into an asphalt mixer includes a vertical feed chute with straight walls that spans substantially a full diameter and a full length of a horizontal feed auger to feed bulk fibrous material by gravity from the feed chute in a radial direction along the length of the feed auger. The feed auger is rotated at a controlled rate proportionally to the rate of production of an asphalt and mineral aggregate mixture. A pneumatic conveying line conveys the reinforcing fibers from an outlet end of the feed auger to an asphalt mixer for mixing with the asphalt and mineral aggregate to produce a fiber reinforced asphalt concrete with an accurately proportioned amount of fiber dispersed therein.

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 %.
