Abstract

Abstract: In order to explore the bonding performance between waterborne epoxy slurry lower seal layer and semi-rigid base of cement pavement, the composite test specimens consisting of “semi-rigid base, waterborne epoxy slurry seal and cement concrete plate” were firstly fabricated by selecting raw materials and designing the mix proportion. On this basis, by means of direct shear test with vertical load, the effects of seal gradation, post seal curing temperature, seal forming temperature and surface contamination degree of semi-rigid base on the bonding performance between waterborne epoxy slurry seal and semi-rigid base were compared and analyzed under different slurry seal binder conditions, and the measures to ensure the bonding performance between the above two were put forward. The experiment results show that compared with matrix emulsified asphalt and SBR modified emulsified asphalt, the bonding performance between waterborne epoxy SBR modified emulsified asphalt slurry seal and semi-rigid base is obviously better. All factors have the same influence on the bonding performance between the seal coat and semi-rigid base course of different binders, which shows that the seal gradation, molding temperature and pollution degree have a great influence on the interlayer bonding performance, while the curing temperature at the late stage has a small influence on the interlayer bonding performance. It is recommended to select the fine-grained slurry seal, lay the seal layer at a molding temperature of 20 ℃ and clean the semi-rigid base before laying to guarantee the bonding performance between the slurry seal and semi-rigid base.

摘要： 为了探究水泥路面水性环氧稀浆下封层与半刚性基层间的黏结性能，首先通过原材料的选取和混合料配合比设计，成型“半刚性基层+水性环氧稀浆封层+水泥混凝土板”组合试验试件。在此基础上，借助具有竖向荷载的直接剪切试验，对比分析不同稀浆封层结合料条件下的封层级配、封层后期养生温度、封层成型温度和半刚性基层表面污染程度对稀浆封层和半刚性基层层间黏结性能的影响，并提出保证二者层间黏结性能的措施。试验结果表明：相比于基质乳化沥青和SBR改性乳化沥青，水性环氧-SBR改性乳化沥青稀浆封层与半刚性基层间的黏结性能明显较优；各因素对不同结合料的封层与半刚性基层间的黏结性能影响程度一致，均表现出封层级配、成型温度和污染程度对层间黏结性能影响较大，而后期养生温度对层间黏结性能影响较小的特点；建议采用细粒式封层，在20 ℃的成型温度下铺筑封层且在铺筑前清扫半刚性基层下承层的措施，以保证层间的黏结性能。
