Abstract:
The present invention relates to an asphalt product. The asphalt product includes an asphalt binder and a bio-oil blend comprising a mixture of a non-hydrogenated bio-oil and a partially hydrogenated bio-oil, where the bio-oil blend is mixed with the asphalt binder to form an asphalt product having a shear stiffness of 0.20 kPa to 11,000 kPa at a temperature ranging from 25° C. to 85° C. and/or a viscosity of 0.15 Pa·s to 1.50 Pa·s at a temperature ranging from 120° C. to 165° C. The present invention further relates to methods of producing an asphalt product and methods of applying an asphalt product to a surface.
