    Abstract

    Because of frequent high-temperature weather and increased traffic volume, the rutting of asphalt pavement has become the main technical problem to be resolved. In this paper, seven types of anti-rutting asphalt mixtures, including masterbatch hard asphalt mixture with high-modulus, additive-type anti-rutting asphalt mixture, styrene-butadiene-styrene modified asphalt, and intersection anti-pushing asphalt mixtures A, B, C, and D were proposed. The Chinese and French rutting tests, the flow number test, the evaluation method of anti-pushing performance, and the structural depth attenuation test were used to evaluate the applicability of the following anti-rutting test methods: the evaluation methods and indicators of anti-displacement performance and the evaluation methods and indicators of structural depth attenuation under high-temperature conditions. The test results showed that the dynamic stability (DS) index of the Chinese rutting test was more suitable for evaluating the first stage of rutting development, and the DS index was more suitable for evaluating the second stage of rutting development than the creep rate of the French rutting test. It was reasonable to use the French evaluation method for asphalt concrete (AC) mixtures. The Chinese rutting test was more suitable for the high-modulus asphalt mixture. In addition, improving the high-temperature stability of the asphalt mixture can slow down the attenuation of the anti-slipping property.
