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.
Claims21
An asphalt binder, comprising:
- a bitumen;
- and
- a post-fermentation distillers corn oil comprising one or more triglycerides, one or more diglycerides, one more free fatty acids, one or more phytosterols, and one or more tocopherols, wherein the post-fermentation distillers corn oil comprises less than 1,400 μg of the one or more tocopherols per gram of the post-fermentation distillers corn oil.
An asphalt binder, comprising:
- a bitumen;
- and
- a post-fermentation distillers corn oil comprising one or more triglycerides, one or more diglycerides, one more free fatty acids, one or more phytosterols, and one or more tocotrienols, wherein the post-fermentation distillers corn oil comprises about 500 μg to about 1,800 μg of the one or more tocotrienols per gram of the post-fermentation distillers corn oil.
An asphalt binder comprising:
- a bitumen;
- and
- a post-fermentation distillers corn oil comprising one or more triglycerides, one or more diglycerides, one more free fatty acids, one or more phytosterols, and one or more carotenoids, wherein the post-fermentation distillers corn oil comprises about 60 μg to about 400 μg of the one or more carotenoids per gram of the post-fermentation distillers corn oil.
An asphalt binder, comprising:
- a bitumen;
- and
- a post-fermentation distillers corn oil comprising one or more triglycerides, one or more diglycerides, one more free fatty acids, one or more phytosterols, and one or more tocopherols, wherein the post-fermentation distillers corn oil comprises less than 1,300 μg of the one or more tocopherols per gram of the post-fermentation distillers corn oil comprising the one or more triglycerides, the one or more diglycerides, the one more free fatty acids, the one or more phytosterols, and the one or more tocopherols.
