Pavement repairing structure and pavement repairing method
The invention relates to a pavement repairing structure and a repairing method, and relates to the field of pavement repairing technologies, the pavement repairing structure comprises a bottom layer, a reinforcing layer and a finishing coat which are sequentially laminated from top to bottom; the bottom layer is prepared by coating a roadbed with a primer and curing the primer, and the primer comprises the following components in percentage by mass: 25-50% of water, 40-55% of epoxy resin, 5-15% of a curing agent, 1-5% of a solvent, 0.1-1% of a rheological additive and 0.1-1% of a thickening agent; the reinforcing layer is an asphalt concrete layer, the reinforcing layer extends to the periphery from the position to be repaired and covers the undamaged position of the original asphalt pavement, and the upper surface of the reinforcing layer does not exceed the original asphalt pavement; and the overlay layer covers the joint position of the reinforcing layer and the original asphalt pavement. According to the technical scheme, the mechanical strength, durability and traffic comfort degree of the repaired asphalt pavement can be effectively improved.
本申请涉及一种路面修复结构及修复方法，涉及路面修复技术的领域，路面修复结构包括由上至下依次叠层设置的底层、补强层和罩面层；所述底层由底涂料涂覆于路基上固化后制得，以质量百分比计，所述底涂料包含以下组分：水25~50%，环氧树脂40~55%，固化剂5~15%，溶剂1~5%，流变助剂0.1~1%，增稠剂0.1~1%；所述补强层为沥青混凝土层，所述补强层由待修复位置向四周延伸并覆盖至原沥青路面未破损处，且所述补强层的上表面不超过原沥青路面；所述罩面层覆盖所述补强层与原沥青路面的接缝位置。本申请技术方案可以有效提升沥青路面修复后的力学强度、耐久性以及通车舒适程度。
