摘要

采用先乳化后改性的方法制备了水性环氧树脂改性乳化沥青,并对水性环氧树脂掺量不同的改性乳化沥青的性能进行了研究,确定了水性环氧树脂的最佳掺量为10%(质量分数)。通过修正马歇尔试验法对水性环氧树脂改性乳化沥青混合料进行配合比设计,确定混合料的最佳乳液含量为9.0%(质量分数),可压实时间为4h。高低温性能、水稳定性能及疲劳性能实验结果表明:与基质沥青、乳化沥青混合料相比,水性环氧树脂改性乳化沥青混合料的高温性能及疲劳性能显著提高,其低温性能良好,水稳定性与基质沥青混合料基本相当且优于乳化沥青混合料。

Abstract

The waterborne epoxy resin(EP) modified emulsified asphalt was prepared using the method of first emulsification and then modification.The performance of the emulsified asphalt with different contents of waterborne EP was studied,and the optimum content of waterborne EP was determined to be 10% (mass ratio).The mix design of waterborne EP modified emulsified asphalt mixture was carried out by modified Marshall test.The optimum emulsion content was 9% (mass ratio) and the compaction time was 4h.The test results showed that the high-temperature performance and fatigue performance of the emulsified asphalt mixture were significantly improved compared with neat asphalt and emulsified asphalt mixture,and its low-temperature performance was good.The water stability of the emulsified asphalt mixture was basically equivalent to that of neat asphalt mixture and better than emulsified asphalt mixture.
