Investigation on Properties of Modified Asphalt Containing Antiaging Agent

Abstract:

The purpose of this work is to investigate the thermal aging and ultraviolet (UV) radiations aging of SBSMA. Antioxidants and UV absorbers were employed to improve the antiaging resistance of SBSMA in this study. The results indicated that the SBSMA with antioxidants has good heat aging resistance, and SBSMA with UV absorbers blends have good photostability. The compound antiaging agents containing antioxidants and UV absorbers are a best choice to prepare SBSMA with better physical and antiaging resistance. The experimental results also indicated that the effects of antiaging agents on the physical properties of SBSMA are little at low contents. Especially conventional physical properties of SBSMA with 1 wt% of ZDDP and 0.5 wt% of UV531 are close to that of SBSMA.
