摘要：In order to ensure the fast and efficient snow removal of roads in winter, a kind of slow-release antifreeze combined with asphalt concrete is developed, and its road performance is studied. In this paper, a kind of antifreeze performance of AC-13 is developed, therefore, the low and high temperature performance, water resistance, damaging antifreeze performance of asphalt mixture are studied under different dosage of antifreeze. Based on the analysis of the performance evaluation of the road at the same time the climate suitability of different antifreeze, this paper studies changes of dosage of antifreeze antifreeze performance decay law of asphalt mixture. The results show that the water damage resistance, low and high temperature performance of the antifreeze mixture are decreased with the increase of the antifreeze dosage, but under the appropriate dosage, the performance of the asphalt mixture could meet the requirements of the specification, and the optimal dosage of AC-13 antifreeze is 5.5%.
