Once it has been verified that a particular material is sustainable, characterization of this new material and its interaction with asphalt is foundational. Vegetable-based materials (e.g., soy) are appealing as flexible pavement materials because of their short-term renewable nature and hydrocarbon chemical structure. Little is published regarding the rheological properties of asphalt–vegetable oil blends. This research investigates some high-temperature rheological properties (i.e., viscosity in terms of mixing and compaction temperatures and complex modulus) of four well-studied SHRP binders and just the complex modulus of a recycled asphalt binder, all modified with 1% and 3% soy fatty acids, a specific portion of soybean oil. These rheological tests show that as soy fatty acids (SFAs) are added in small percentages the binder becomes less stiff and more workable. These results suggest that SFAs have potential application as a fluxing agent for binders that are stiff and hard to mix (e.g., recycled asphalt binders).
