Abstract
Asphalt binders and methods for making and using same. In at least one specific embodiment, the asphalt binder can include a bitumen and a glyceride and fatty acid mixture. The glyceride and fatty acid mixture can include one or more triglycerides, at least 1 wt % of one or more diglycerides, and at least 5 wt % of one or more fatty acids, based on the combined weight of the one or more triglycerides, the one or more diglycerides, and the one or more fatty acids. The asphalt binder can be made by combining a bitumen and a glyceride and fatty acid mixture. A paving composition can be made by combining a plurality of solids and the asphalt binder. A road can include a plurality of solids mixed with the asphalt binder.
Claims26
An asphalt binder, comprising:
- a bitumen;
- and
- a glyceride and fatty acid mixture comprising about 60 wt % to about 92 wt % of one or more triglycerides, at least 1 wt % of one or more diglycerides, and at least 5 wt % of one or more free fatty acids, based on the combined weight of the one or more triglycerides, the one or more diglycerides, and the one or more free fatty acids.
A method for making an asphalt binder, comprising:
- combining a bitumen and a glyceride and fatty acid mixture to produce an asphalt binder, wherein the glyceride and fatty acid mixture comprises about 60 wt % to about 92 wt % of one or more triglycerides, at least 1 wt % of one or more diglycerides, and at least 5 wt % of one or more free fatty acids, based on the combined weight of the one or more triglycerides, the one or more diglycerides, and the one or more free fatty acids.
A method for making a paving composition, comprising:
- combining a plurality of solids with an asphalt binder to produce a paving composition, wherein the asphalt binder comprises a bitumen and a glyceride and fatty acid mixture, and wherein the glyceride and fatty acid mixture comprises about 60 wt % to about 92 wt % of one or more triglycerides, at least 1 wt % of one or more diglycerides, and at least 5 wt % of one or more free fatty acids, based on the combined weight of the one or more triglycerides, the one or more diglycerides, and the one or more free fatty acids.
An asphalt binder, comprising:
- a bitumen;
- and
- about 1 wt % to about 25 wt % of a post-fermentation distillers corn oil, based on a combined weight of the bitumen and the post-fermentation distillers corn oil, wherein the post-fermentation distillers corn oil comprises about 74 wt % to about 86 wt % of triglycerides, about 3 wt % to about 5 wt % of diglycerides, and about 11 wt % to about 16 wt % of free fatty acids, based on the combined weight of the triglycerides, the diglycerides, and the free fatty acids.
