In order to address the influence of aging on the performance degradation of SBS-modified asphalt, a composite modification of\nSBS-modified asphalt by nano-zinc oxide (nano-ZnO) and Trinidad Lake asphalt (TLA) was proposed. Several tests were\nconducted after adding nano-ZnO and TLA to SBS-modified asphalt, including a rotary film oven test (RTFOT), ultraviolet aging\n(UV), and the pressure aging vessel test (PAV). The conventional physical index, rheological index, and four-component content\nof SBS-modified asphalt before and after three aging modes were tested, and the characteristic functional groups in SBS-modified\nasphalt were tracked and analyzed by Fourier transform infrared spectroscopy (FTIR)........................
