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.
Claims25
A polymerized oil comprising:
- a biorenewable, previously modified, or functionalized oil crosslinked with a sulfur-containing compound and having
- (a) a polymeric distribution having about 2 to about 80 wt % oligomer content;
- (b) a polydispersity index ranging from about 1.30 to about 2.20;
- and
- (c) sulfur content ranging from 0.001 wt % to about 8 wt %.
A modified asphalt, comprising:
- (a) about 60 to about 99.9 wt % asphalt binder;
- and
- (b) about 0.1 to about 40 wt % polymerized oil crosslinked with a sulfur-containing compound and comprising
- 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 %.
A method of incorporating a polymerized oil in asphalt applications, comprising:
- (a) obtaining a polymerized oil crosslinked with a sulfur-containing compound, the polymerized oil comprising:
- 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 %;
- and
- (b) adding the polymerized oil to treat reclaimed asphalt pavement millings (RAP) to be reused in asphalt pavements, thereby obtaining a modified asphalt;
- wherein the amount of the polymerized oil ranges from 0.1 to 40 wt % of the modified and rejuvenated asphalt.
