Paper Title:
Research on Performance of Sasobit Warm Mix Asphalt and Influence of Aging Using DSR
  Abstract

In order to study the performance of Sasobit warm mix asphalt and the influence of aging, complex shear modulus G* and phase angle δ of Sasobit warm mix asphalt are tested by Dynamic Shear Rheometer (DSR) at different aging phase, to analyze the effects of Sasobit to the performance and the aging of 70# and SBS asphalt. The results show that with the increasing of the dosage of Sasobit, the value of G*/sinδ can be increased at different aging phase, the change in the phase angle has the same trend; the degree of Long-term aging of warm-matrix asphalt is larger than modified asphalt's. This may be related to the interaction of Sasobit and modifier.
