摘要：配制了双组份甲基丙烯酸甲酯MMA快速修补材料，通过加入引发剂使其聚合反应形成修补层，研究了引发剂用量对修补液固化时间的影响，确定了常温下引发剂的最佳用量。依据JTG F40—2004《公路沥青路面施工技术规范实施手册》冷拌沥青混合料质量检验标准，试验了双组份MMA快速修补材料的快速固化性能、抗水损剥落性能、低温工作性能和粘结性等指标。结果表明，双组份MMA快速修补材料的抗水损剥落性能中裹覆面积大于99%，粘结强度大于5.87 MPa，粘聚性破损率小于18%，马歇尔稳定度平均值为8.79 kN，可以满足路面快速修补要求。

Abstract：In this paper，a two-component MMA fast repairing material was prepared and the repairing layer was formed by adding initiator. The effect of the amount of initiator on the curing time of repairing material was studied，and the optimum amount of initiator at room temperature was determined. According to the quality inspection standard of cold mix asphalt mixture in the JTG F40—2004 "Implementation Manual of Technical Specifications for Construction of Highway Asphalt Pavements"，the fast solidification performance，anti-water loss and spalling performance，low temperature workability and cohesion of two-component MMA pavement repair material are tested. The results show that the two-component MMA pavement repair material can fully meet the requirements of rapid pavement repair with coating area larger than 99%，bond strength more than 5.87 MPa，cohesive damage rate less than 18%，and average value of marshall stability of 8.79 kN.
