The effect of adding residues obtained under various processing conditions to asphalt cements has been investigated. Results show that from 8 to 14 wt % of a process residue can be blended with asphalt cement to produce an asphalt blend of 85-100 penetration. The amount of process residues that can be added increases with decreasing severity of processing conditions. Asphalt properties have been correlated in terms of composition (saturates, aromatics, resins, and asphaltenes) as well as average molecular weight of the asphaltenes and maltenes determined by gel permeation chromatography. The results are compared with two virgin asphalt cements.
