Abstract
Hansen solubility parameters of aged asphalts and rejuvenators were determined by dissolving method with twenty seven solvents, whose Hansen solubility parameters were known. The computation program was used to perform sphere simulation for the soluble points, in which the center was the Hansen solubility parameter of sample. About 80% of the simulation results were consistent with the experimental data. The Hansen solubility parameters differences between rejuvenator A2 and three aged asphalts were small, which indicated compatibilities of them were good. The compatibilities between rejuvenator D and three aged asphalts were bad.
