• Asphalt mixtures containing anti-freeze filler with different particle size are researched in this paper.
• High- and low-temperature properties and the susceptibility to moisture damage are investigated, as well as conductivity test was carried out to research the influence on performance of the AFACs.
• Estimating model is developed based on the colligative property of dilute solution, and was proved with observation experiments.
• A better anti-freeze property of AFAC will be obtained in a little precipitation and high temperature conditions.
This paper focused on the properties of asphalt mixtures containing anti-freeze filler (ICB-1, ICB-2, ICB-3 and ICB-4) with the volume replacement method. And the void content, high- and low-temperature properties and the susceptibility to moisture damage are investigated by experimental method. Based on the colligative property of dilute solution, a new evaluating model is developed, and proved with observation test. The result shows that the asphalt mixture containing a smaller particle obtains a better high- or low-temperature property, and water stability. Furthermore, it is believed that a better anti-freeze property of asphalt mixtures will be obtained in a little precipitation and high temperature conditions. Besides, in heavy event, a liquid layer appears between pavement and snow/ice, which would facilitate the mechanical removal of the snow or ice.
