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.
