【摘要】：采用正交試驗法研究微表處高性能苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)改性乳化瀝青的制備工藝,依據(jù)微表處和改性乳化瀝青的性能要求對其測試評價。最佳制備工藝為:改性劑用量以3%為基準以±l%進行試配,乳化劑A初始摻量為1.9%,穩(wěn)定劑摻量2‰,油水比為60∶40,皂液溫度為65℃,瀝青溫度為165℃,皂液pH值為1.5~2.5,乳化時間為5min,制得的高性能SBS改性乳化瀝青成型的微表處混合料的可拌合時間為160s,粘結(jié)強度為1.3MPa,6d濕輪磨耗損失為628g/m~2,具有較好的性能。
[Abstract]:The preparation process of high performance styrene-butadiene-styrene block copolymer (SBS) modified emulsified asphalt at microsurface was studied by orthogonal test. The optimum preparation technology is as follows: the dosage of modifier is 3% and 鹵1%, the initial amount of emulsifier A is 1.9%, the amount of stabilizer is 2 鈥，
