Abstract

This study conducts orthogonal experiments on a single-component epoxy resin curing system (SCECS) for repairing asphalt pavement cracks based on orthogonal table of $L_{18} (3^{7})$ to optimise its material proportion and preparation technology; slurry viscosity, curing of the tensile bond strength, tensile strength, and breaking elongation were adopted as the performance evaluation indices. The results showed that the mixing time, water volume, toughening agent amount, and curing agent amount are factors that have the most significant influence on the performance evaluation indices of the cured material. The optimal epoxy resin main agent, diluent and toughening agent ratio of epoxy resin base fluid is 1:2:3, the optimal PCA dosage is 20% of epoxy resin base fluid, and the optimal water dosage is 30% of the total amount of epoxy resin base fluid and PCA. The optimal preparation condition of the SCECS are 30% water consumption, 60 °C water temperature, 5 min stirring time, and 600 r/min stirring speed.

沥青路面裂缝修补用单组分环氧树脂材料配比及制备工艺的正交试验分析

本研究基于L1837正交表对修复沥青路面裂缝的单组分环氧树脂固化体系(SCECS)进行正交试验，优化其材料配比和制备工艺;采用浆料粘度、固化拉伸粘结强度、拉伸强度和断裂伸长率作为性能评价指标。结果表明，混合时间、水体积、增韧剂用量、固化剂用量是影响固化材料性能评价指标最显著的因素。环氧树脂基液中环氧树脂主剂、稀释剂和增韧剂的最佳配比为1:2:3,PCA的最佳用量为环氧树脂基液的20%，PCA的最佳水用量为环氧树脂基液和PCA总量的30%。SCECS的最佳制备条件为用水量30%、水温60℃、搅拌时间5 min、搅拌速度600 r/min。

期刊介绍： Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged. Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
