摘　　要：研究分析水性环氧乳化沥青应用于排水路面建设用OGFC-13级配混合料粘结的可行性。采用环氧树脂对马来酸酐接枝沥青进行改性并制得乳化沥青,试验结果表明,当环氧树脂掺量为10%时,能显著改善乳化沥青的力学性能,且所制备的水性环氧乳化沥青具有良好的存储稳定性和粘附性。同时研究了OGFC-13型(开级配)混合料的配合比设计、成型、养生工艺以及路用性能,结果表明,最佳混合料击实方法和养生条件为:先正反击实50次,放入烘箱40℃养生6 h,再击实25次,然后升温至80℃养生24 h;当水性环氧乳化沥青掺量为矿物质量的9.5%时,混合料具有优异的高低温性能及良好的水稳定性,符合JTG F40—2004《公路沥青路面施工技术规范》的要求。This study explores the feasibility of applying water-based epoxy emulsified asphalt to OGFC-13 grading mixture for drainage pavement construction.The emulsified asphalt is modified with epoxy resin.The results showed that when the dosage of epoxy resin was 10%,the mechanical properties of emulsified asphalt could be significantly improved,and the prepared water-based epoxy Emulsified asphalt has good storage stability and high adhesion.The proportion design,molding and curing process and road performance of the OGFC-13 type(open grading)mixture were studied.The results showed that the best compaction method and curing conditions of the mixture were 50 times of counterattack,and then placed in an oven at 40℃for 6 hours.After 25 times of counterattack,the temperature was raised to 80℃for 24 h,when the addition amount of water-based epoxy emulsified asphalt was 9.5%,it showed excellent high and low temperature performance and good water stability,which met the requirements of JTG F40—2004"Technical Specification for Construction of Highway Asphalt Pavements".
