To study the long-term salt-release characteristics of self-melting asphalt mixture and the effect of complete salt release on pavement durability, Firstly, based on the Los Angeles abrasion meter, a method to accelerate the quick release of salt from the self-melting asphalt mixture was designed. Secondly, the law of salt release under different asphalt type, deicing agent content and gradation type is revealed. Finally, the effect of salt release on road performance was analyzed. The results show that the salt release efficiency of the Los Angeles abrasion apparatus salt release method is 91 times higher than that of the magnetic rotator salt release method and 114 times higher than that of the natural immersion salt release method. SBS modified asphalt has a longer salt release time for self-melting ice asphalt mixture. The salt release time is proportional to the amount of deicing agent. The salt release uniformity of SMA-13 self-melting ice asphalt mixture is poor. After complete salt release, high-temperature stability of self-melting ice asphalt mixtures decreased by 31.6%, low-temperature performance decreased by 15.4%, water stability decreased by 26.7%.
