Effects of Various Rejuvenator Sealer Materials on Rheological Properties of Aged SBS Modified Asphalt

Abstract:

In recent years, using rejuvenator sealer materials (RSMs) to recover the performance of aged asphalt on the pavement is becoming more and more popular. In this paper, four different RSMs were made and applied to rejuvenate the aged asphalt which experienced a PAV 20H process. Then the dynamic rheological characteristics of different binders were tested by the dynamic shear rheometer (DSR).The results indicated that the four RSM can recover the stress relaxation and fatigue factor of aged asphalt. But the rutting parameter decreased with the introduction of four RSMs.
