摘　　要：基于表面活性技术温拌剂降温机理,开展了表面活性技术温拌剂合成工艺及性能测试研究,试验结果表明:棕榈酸酰胺丙基二甲基胺的最佳合成条件为:酸胺的摩尔比为1:1.2,反应时间为5 h,反应温度为120℃。将合成的棕榈酸酰胺丙基二甲基胺与硫酸二甲酯按1:1摩尔比反应,合成出季铵盐温拌剂,并采用红外光谱和元素分析法验证了结构特征。该季铵盐温拌沥青混合料相比于热拌沥青混合料,能有效降低成型温度30℃,同时各项路用性能均满足现行规范要求。The mechanism for warm-mix agent based on surfactant technology was introduced.Test results show that the best synthesis route is as follows：molar ratio of palmitic acid to N,N-dimethyl-1,3-propane diamine is 1：1.2,reacting for 5 h,at 120 ℃.Palmitic acid amide propyl dimethyl amine and dimethyl sulfate molar react with the ratio of 1：1.Then,warm-mix agent of quaternary ammonium salt is synthesized.Its structure property is tested by IR and elemental analysis.The compaction temperature of asphalt mixture could decrease by 30℃ if the warm-mix agent of quaternary ammonium salt is used.And aslo the pavement performance of warm-mix asphalt could meet the requirement of current specification.
