摘　　要：针对沥青路面早期病害维修对修补材料的特殊要求,开展了半柔性路面修复材料早强型水泥乳化沥青混凝土的设计及应用研究。通过试验研究和实际工程应用获得了早期强度高、粘结性能好、后期耐久性好、开放交通时间短、对环境友好的路面修补材料,且实体工程应用证明早强型水泥乳化沥青混凝土修补材料具有良好使用效果。This paper presented a study in which the semi-flexible patching materials of high early strength cement emulsified asphalt mixture was developed according to the particular requirements for cor- recting initial distress of asphalt pavement. The lab tests and demonstration test road indicated that the de- veloped environmentally-friendly patching material performed better in early strength, bonding ability, and durability. The performance of patching material was also demonstrated by the field validation test.
