The rheological behavior of rejuvenated SBS modified asphalt incorporating oil slurry and tri-epoxide

摘要

The viscous-elastic behavior, noise reduction and viscosity-temperature susceptibility of aged SBS modified asphalt (SBSMA) incorporated with fluid catalytic cracking slurry (FCC) and Trimethylolpropane triglycidyl ether (TMPGE) were investigated. The results indicate that the viscous-elastic temperature of rejuvenated binder will shift to a lower temperature due to the asphaltic composition adjustment and the agglomerate dispersion of the rejuvenators on aged binder; the viscous loss of binders relies upon their irreversible deformation; the rejuvenated binder makes contributions on reducing the vibration noise in comparison with aged one; the rejuvenated binder has a low viscosity that suitable for processing and pumping, and exhibits a weakening viscous-temperature susceptibility.
