Anti-freezing asphalt concrete composite and manufacturing method thereof

The invention discloses an anti-freezing asphalt concrete composite, and relates to the technical field of roads. The anti-freezing asphalt concrete composite is prepared from, by weight, 20-25 partsof crushed crude pearlite, 10-15 parts of coal ash, 50-65 parts of asphalt, 30-35 parts of building stones, 30-35 parts of stone sand, 8-17 parts of organic silicon resin, 8-17 parts of polyurethane,0.3-0.5 part of PVC heat stabilizer and 1-3 parts of polyimide. When the anti-freezing asphalt concrete composite is adopted for road pavement, the anti-freezing capability of a road surface is enhanced, and the phenomenon that the road surface is damaged by freezing is effectively avoided. 本申请公开了道路技术领域的种防冻沥青混泥土组合物，包括以下原料，珍珠岩粉、粉煤灰、沥青、石料、石沙、有机硅树脂、聚氨酯、PVC热稳定剂和聚酰亚胺，各原料的重量份数为：珍珠岩粉20～25份、粉煤灰10～15份、沥青50～65份、石料30～35份、石沙30～35份、有机硅树脂8～17份、聚氨酯8～17份、PVC热稳定剂0.3～0.5份和聚酰亚胺1～3份。采用本发明用于道路的铺设时，就加强了路面的防冻能力，并且有效的防止因结冰而损伤路面。
