Aging evaluation of base and SBS modified bitumens under the coupling effect of multiple aging factors

The thermal-oxidative aging of bitumen is extensively studied under the guidance of current norms in laboratory investigations, while the photo-oxidative aging is not standardized and the moisture is seldom considered. To evaluate the aging behaviors of bitumen under the coupling effect of multiple aging factors, two binders, a base bitumen and an SBS modified bitumen (SBSMB), were treated by different aging inducements, such as heat, oxygen, …
