摘要

针对沥青路面裂缝修补材料存在的问题，研制了一种成型强度高、韧性好、室温固化的环氧树脂胶粘剂。除了用作道路填充密封胶外，该粘合剂还可用于制备凹坑的冷修补混合物。研究了环氧树脂胶粘剂的性能、浇注密封胶和冷贴的施工性能和路用性能。结果表明:该环氧树脂胶粘剂早期强度快、强度高，固化体积收缩率小，低温特性和拉伸性能好，韧性优异。作为浇注密封胶，环氧树脂胶粘剂具有优良的耐低温弯曲性能。基于该胶粘剂的冷补料具有较强的粘结性、良好的低温抗裂性、优异的高温稳定性和水稳定性。该胶粘剂拓展了环氧树脂在沥青路面裂缝、坑修补中的应用，对促进沥青路面养护技术的发展具有重要意义。

EPOXY-RESIN ADHESIVE FOR SEAM FILLING AND POTHOLE REPAIR IN PAVEMENT MAINTENANCE

Aiming at the problems of asphalt pavement crack sealing and pothole repair materials, an epoxy-resin adhesive with high forming strength, good toughness and room-temperature curing was prepared. In addition to being used as a road filling sealant, the adhesive can also be used for preparing a cold patching mixture for pits. The properties of the epoxy-resin adhesive, the construction performance and road performance of the pouring sealant and cold patch were studied. The results showed that the early strength of the epoxy-resin adhesive was fast and high, the curing volume shrinkage was small, the low-temperature characteristics and tensile properties were good, and the toughness was excellent. As a pouring sealant, the epoxy-resin adhesive had excellent low-temperature bending resistance. The cold patching mixture based on the adhesive exhibited strong cohesiveness, good low-temperature crack resistance, and excellent high-temperature stability and water stability. This adhesive expands the application of epoxy resin in repairing cracks and pits of asphalt pavements, and is of great significance in promoting the development of the asphalt pavement maintenance technology.
