The invention discloses a warm-mix composite anti-rut agent as well as a preparation method and application thereof. The warm-mix composite anti-rut agent comprises rock asphalt and oxidized polyethylene wax, wherein the ratio of the rock asphalt to the oxidized polyethylene wax in percentage by weight is (1%-99%):(99%-1%). The warm-mix composite anti-rut agent disclosed by the invention can be used for preparing a composite modified asphalt mixture by using a wet process or a dry process to be applied to asphalt pavement construction, has the advantages of good high temperature stability, low construction temperature, energy saving and environmental protection and reaches the double effects of warm mixing and rutting prevention, thereby being beneficial to improving the pavement performances, lowering the construction cost and having good economic, social and environmental benefits. 本发明公开了种温拌型复合抗车辙剂及其制备方法与应用。所述温拌型复合抗车辙剂由岩沥青和氧化聚乙烯蜡组成，其中以重量百分数计，岩沥青与氧化聚乙烯蜡的配比为1％～99％:99％～1％。本发明的温拌型复合抗车辙剂可采用湿法或干法制备复合改性沥青混合料应用于沥青路
