Production method of anti-freezing type bridge deck pavement asphalt concrete
The invention relates to a production method of anti-freezing type bridge deck pavement asphalt concrete. The method comprises the following steps: covering a mixture of soluble chloride crystals and calcium oxide into a porous igneous rock to acquire a freezing alleviator with a porous structure, wherein the mass rate of the soluble chloride crystals to the calcium oxide is (40-60):(40-60); and uniformly mixing the freezing alleviator with the asphalt concrete to acquire the anti-freezing type bridge deck pavement asphalt concrete, wherein the mass rate of the mixture of soluble chloride crystals and calcium oxide to the asphalt concrete is (1-6):(94-99). By using the asphalt concrete produced by the method, the difficulty of snow removal in winter can be reduced; after the snowy winter, the covered chloride can be separated out through the porous structure, so that the freezing point of the snow accumulated on the road is reduced; moreover, the ice and snow is converted into liquid water or water vapor so as to be drained out of a road surface, and therefore, the effects of removing the ice and thawing the snow are achieved.
