The deterioration of asphalt binders rheological behaviors in different aging stages were investigated by using self-developed indoor aging equipment SAT (simple aging test), and the corresponding relationship between indoor simulated aging and field asphalt aging was established. It was found that SAT equipment can better simulate the aging process of asphalt on site, with asphalt film thickness of 2 mm, short-term aging temperature at 150 °C, long-term aging temperature at 95 °C.
