Phase-change anti-freezing material and pavement anti-freezing fine surface construction method

The invention relates to a phase-change anti-freezing material and a pavement anti-freezing fine surface construction method. The phase-change anti-freezing material comprises, by weight, 50-60 parts of matrix asphalt, 20-30 parts of epoxy resin, 10-15 parts of a curing agent, 5-10 parts of a phase-change material and 0.5-1.0 part of polyphosphoric acid. The phase-change material comprises, by weight, 2-4 parts of fatty acid and 3-6 parts of straight-chain alkanes. The fatty acid is selected from one or more of decanoic acid, lauric acid, tetradecanoic acid, palmitic acid and stearic acid, and the number of carbon atoms of the straight-chain alkane is 10-15. The phase change anti-freezing material can achieve a good anti-freezing effect, is friendly to the surrounding environment, saves the anti-freezing material and is good in economical efficiency. 本发明涉及一种相变抗凝冰材料和路面抗凝冰精表处施工方法，所述相变抗凝冰材料包含如下重量份的组分：50～60份基质沥青、20～30份环氧树脂、10～15份固化剂、5～10份相变材料和0.5～1.0份多聚磷酸，其中，所述相变材料包含以重量份计的2～4份脂肪酸类和3～6份直链烷烃，所述脂肪酸类选自葵酸、月桂酸、十四烷酸、棕榈酸
