Abstract

This paper aims to investigate the aging behavior of high viscosity/SBS compound modified asphalt. To this end, asphalt specimens with different aging degrees were prepared separately, the fluidity of asphalt was evaluated by viscosity test, the adhesion between asphalt and aggregate before and after aging was investigated by contact angle test, and finally the correlation between the fluidity of asphalt and its adhesion was explored based on the gray correlation theory. The results showed that aging had a significant effect on the Newtonian fluid state of asphalt, but the trend and degree of the effect were related to the type of asphalt. Aging weakened the adhesion between asphalt and aggregate, but the compounding of high viscosity agents with SBS could slow down this aging effect. Asphalt fluidity can be used to predict its ability to adhere to aggregates, which in turn guides the design and construction of asphalt mixtures.
