摘要:
为进一步促进水性环氧乳化沥青(waterborne epoxy resin emulsified asphalt，WEREA)在微表处的发展及应用，以普通乳化沥青为对照组，研究了水性环氧树脂(waterborne epoxy resin，WER)掺量分别为5%、10%、15%、20%、25% 时，WEREA 的基本性能和黏附性能，并测试了其微表处耐磨耗、抗车辙、抗水损害性能。结果表明，WEREA 蒸发残留物的软化点随着wWER 增加而上升，而针入度及延度下降；wWER增加导致集料的沥青损失率减少；此外，微表处磨耗值、车辙深度率和宽度变形率均随着wWER增加而降低，冻融劈裂抗拉强度比随wWER 增加而增大。故WER 提高了乳化沥青的高温稳定性和黏附性，但会表现出低温脆性；基于微表处混合料，WER 改性对其耐磨耗、抗车辙及水稳定性也有良好的改善效果。综合考虑性能及成本，推荐wWER为15%。
Abstract:
In order to further promote the development and application of waterborne epoxy resin emulsified asphalt （WEREA） in micro-surfacing, the basic properties and adhesion properties of WEREA were studied when the content of waterborne epoxy resin （WER） was 5%, 10%, 15%, 20% and 25% respectively, and the wear resistance, rutting resistance and water damage resistance of WEREA in micro-surfacing were studied with ordinary emulsified asphalt as the control group. Test results show that the softening point of WEREA evaporation residue increases with the increase of WER content, while the penetration and ductility decrease. The increase of WER content leads to the decrease of asphalt loss rate of aggregate. In addition, the wear value, rut depth rate and width deformation rate of micro-surface decreases with the increase of WER content, and freeze-thaw cycle splitting tensile strength ratio increases with the increase of WER content. Therefore, WER improves the high temperature stability and adhesion of emulsified asphalt, but it will show low temperature brittleness；based on the micro-surfacing mixture, WER modification also has a good improvement effect on its wear resistance, rutting resistance and water stability. Considering the performance and cost, the recommended WER content is 15%.
