摘　　要：针对工程使用温拌剂时缺乏明确的参考依据,系统调查了国内外温拌剂应用状况,确定温拌改性技术主要分类以及目前常用温拌剂种类,全面评价了Sasobit、Aspha-min、Evotherm与EC120等4种常用温拌剂对沥青混合料高温性能、低温性能以及水稳定性等路用性能的影响。结果表明:几种温拌剂的降温效果均可达到30℃,Sasobit和EC120温拌剂对沥青混合料高温稳定性均有不同幅度提高,最大提高幅度在30%以上,4种温拌剂对沥青混合料低温性能略有影响,对水稳定性的影响均不大。According to using warm mix agent without clear reference in the project, the situation of warm mix agent at home and abroad is investigated systematically. The technology classification and types of common warm mix modification are determined. The influence of Sasobit, Aspha-min, Evotherm and EC120 on the road performance including high temperature performance, low temperature performance and water stability are overall evaluated. The results show that the cooling effect of several warm mix modifier can reach 30 ℃, and the high temperature ：stability performance of asphalt mixture by Sasobit and EC120 have different amplitude increase, the maximum increase of 30 %. The four kinds of warm mix modifier have little effect on the low temperature performance of asphalt mixture, and the effect of the water stability is not obvious.
