Fluid catalytic cracking slurry (FCC) is a kind of organic compounds with rich aromatics, similar to the bituminous chemical components, which can improve the properties of aged asphalt binder with the supplement of aromatics. Trimethylolpropane triglycidyl ether (TMPGE) is a low-viscosity chemical reagent owning three reactive epoxy end-groups, which can react with oxygen-containing groups (for e.g. –COOH and –OH) formed on degraded polymer. On this basis, the new proposal regarding the rejuvenation of aged SBSMA with the usage of FCC and TMPGE can be determined.
