Abstract: In order to clarify the effect of T622 hindered amines light stabilizer (T622) on the anti-ultraviolet aging performance of base asphalt, T622 decay-delayed modified asphalt was prepared. Based on the three major indicators of asphalt, the basic properties of asphalt after UV aging treatment were studied, the apparent viscosity was analyzed by Brookfield viscosity test, and the thermophysical properties and functional group composition of base asphalt and modified asphalt were evaluated by means of thermogravimetric and infrared combined technology. The test results show that the addition of T622 modifier can significantly reduce the influence of ultraviolet aging on the basic properties of the base asphalt, significantly increase the apparent viscosity of the asphalt, and effectively improve the anti-ultraviolet aging performance of the asphalt material. The maximum infrared absorption peak temperature, initial decomposition temperature and functional group index of the base asphalt increases significantly with the aging time, while the relevant indexes of T622 modified asphalt remains in a stable range, and the functional group index is smaller than that of the base asphalt, which verifies from the microscopic level the excellent anti-ultraviolet aging performance of T622 modified asphalt.

Key words: asphalt, hindered amines light stabilizer, ultraviolet aging, performance, characterization
