•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.
