Abstract: In order to clarify the effect of low-temperature performance of warm-mixed asphalt mixture from warm-mixed agent and heating aging, the trabecular creep experiments, which are about original asphalt mixture, short-term aging and long-term aging asphalt mixture, were conducted by UTM-100 at temperature of 0℃, -10℃ and -20℃. The results show that the Burgess model parameter can be fitted by using the creep test data, then the temperature and strain energy density can be calculated, and the cracking temperature of the warm-mixed asphalt mixture can be predicted based on the creep test results, which can be used as a comprehensive index for the low-temperature performance of the asphalt mixture. The delayed mixing method can be taken as a method of characterizing the average aging degree of asphalt mixture in short-term aging process. The low-temperature performance of asphalt mixture at different temperatures and different aging degrees changes because of the fitting parameters. Warm-mixed agent can increase the short-term aging performance of asphalt mixture to a certain extent. It is found that the low-temperature performance of asphalt mixture can be reduced by adding RH warm-mixed agent, while Evotherm warm-mixed agent is beneficial to the low-temperature performance of asphalt mixture, so the Evotherm warm-mixed agent is recommended to be used in the cold area.
