abstract = "The reversibility of aging and recycling of bitumen directly influences the recycling efficiency and durability of recycled pavement. Rolling thin film oven (RTFO) and pressure aging vessel (PAV) were conducted to simulate the different degrees of aging process. The rheology, adhesion and chemical properties of bitumen samples at different aging and recycling stages were characterized by dynamic shear rheometer (DSR), contact angle test and Fourier transform infrared spectroscopy (FTIR). The results reveal that the complex modulus of short-term aged bitumen can be completely recovered to the level of virgin bitumen. The complex modulus of long-term aged bitumen can also be recovered, but higher than that of virgin bitumen. Aging reduced the adhesion between bitumen and limestone. The anti-stripping agent can increase the adhesion of both short-term aged bitumen and long-term aged bitumen by 19.0\% and 44.8\%, respectively. The carbonyl index and sulfoxide index increased by 3614.6\% and 441.9\% after long-term aging, and decreased by 54.0\% and 40.5\% after being recycled, respectively. The revelation of reversibility of aging and recycling of bitumen can help to understand the mechanism of aging and recycling and improve the recycling technology.",
