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.
