中文摘要：

通过自制水性环氧乳液对阳离子乳化沥青进行改性,制备水性环氧乳化沥青及其混合料,开发了一种适用于路面养护的新型修补材料。对不同水性环氧乳液掺量下的水性环氧乳化沥青进行荧光、抗剪、黏附性分析,及其沥青混合料养生条件、马歇尔稳定度、抗劈裂强度、水稳定性测试。结果表明：水性环氧乳液掺量10%-20%时,沥青充分包裹在环氧网络结构中,抗剪强度迅速增大,黏附性较好,掺量小于10%对抗剪强度贡献不大;混合料养生条件在60℃时,随着掺量的增大,马歇尔稳定度、劈裂强度、水稳性随着增大,水性环氧乳液掺量20%时,马歇尔稳定度、抗劈裂强度、MS分别为5.81kN、0.81 MPa、93.1%,均满足规范要求。

英文摘要：

A new repair material for pavement maintenance is developed by modifying the cationic emulsified asphalt and preparing the water based epoxy emulsion asphalt and its mixture. The waterborne epoxy asphalt emulsion waterborne epoxy resin emulsion of different dosage of fluorescence, shear, adhesion and material analysis, health conditions, asphalt mixture Marshall stability, anti cracking strength and water stability test. The results show that the waterborne epoxy resin emulsion asphalt admixture of 10%-20%, fully wrapped in the epoxy network structure, the shear strength increases rapidly, the adhesion is good, the content is less than 10% against the sma｜l shear strength contribution; mixture curing conditions at 60 degrees, with the increase of dosage of Marshall stability, splitting strength and water stability with the increase of waterborne epoxy emulsion dosage to 20% Marshall stability, anti cracking strength and MS are 5.81 kN, 0.81 MPa, 93.1%, both meet the requirements of specification.
