摘　　要：高性能黏层材料对超薄磨耗层层间黏结和结构耐久性至关重要。通过正交试验分析了改性剂的剂量、沥青温度以及皂液pH、乳化时间等对高性能改性乳化沥青性能影响,结果表明：当选用改性剂剂量4%,沥青温度165℃,皂液pH为2~3,乳化时间5 min时为高性能改性乳化沥青的最佳配比。High - performance interlayer bonding materials is essential for interlayer adhesion and dura- bility of ultra - thin wearing course. The impacts of dose of modifier, bituminous temperature, soap pH and e- mulsification time on the high - performance modified emuIsifled asphalt were analyzed through orthogonal test. The results showed that 4% of modifier dosage, 165℃ for bituminous temperature, soap pH2 -3 and 5min for emulsification time were the optimum ratio of high - performance modified emulsified asphalt.
