为确定环氧沥青胶结料最佳制备工艺和高比例温再生混合料最佳成型工艺，采用四因素三水平正交试验法，对环氧沥青胶结料断裂应变进行分析，得到了其最佳制备工艺为高温固化温度150℃，高温固化时间1.5h，低温固化温度60℃，低温固化时间4d。采用最佳制备工艺，对环氧沥青胶结料不同制备阶段进行荧光显微观察，获得不同固化阶段环氧沥青胶结料的微观形貌，验证了其最佳制备工艺合理可行。根据环氧沥青胶结料的最佳制备工艺，结合工程养生实际要求，使用马歇尔试验法确定了环氧改性高比例温再生沥青混合料的最佳成型工艺，即在150℃高温均匀拌合后，保温30min，成型马歇尔试件，再在150℃下继续固化4h，最后常温养生12h，其强度及其他路用性能指标可达到开放交通技术要求。
