The invention discloses an asphalt anti-stripping agent containing an ether material, asphalt and a preparation method of the asphalt anti-stripping agent. The asphalt anti-stripping agent comprises 1.5-2.5 parts by weight of octadecylamine polyoxyethylene ether, 50-110 parts by weight of calcium hydroxide powder and 5-10 parts by weight of a silane coupling agent. The three components interact with each other and are combined with the asphalt to form a more continuous and stable structure. By adding the asphalt anti-stripping agent, not only can the adhesion of asphalt and aggregate be improved, but also the water stability of an asphalt mixture can be improved, and the water damage problem of an asphalt pavement is reduced. Meanwhile, the anti-stripping agent provided by the invention has low requirements on synthesis equipment, is convenient to use, and can also reduce segregation between the asphalt and the anti-stripping agent. 本发明公开一种含醚类材料的沥青抗剥落剂、沥青及其制备方法，沥青抗剥落剂包括1.5-2.5重量份十八胺聚氧乙烯醚、50-110重量份氢氧化钙粉末、5-10重
