Composite structure for inhibiting reflection cracks of asphalt pavement and transformation method
The invention discloses a composite structure for inhibiting reflection cracks of an asphalt pavement and a transformation method, and relates to the technical field of road repair, and the key points of the technical scheme are that the composite structure comprises a self-flowing adhesive filled in a joint; the anti-cracking layer is laid on the cement concrete base layer and completely covers the joint; the stress release layer covers the anti-cracking layer and is rich in elasticity, a plurality of reserved cracks perpendicular to the length direction of the joint are formed in the stress release layer, the reserved cracks correspond to the joint in position, each reserved crack is filled with filler, and the filler can be extruded and exploded when pressed and release bonding substances; and the asphalt concrete surface layer is laid on the stress release layer. The composite structure for inhibiting the reflection cracks of the asphalt pavement and the transformation method can effectively prevent or delay the reflection cracks caused by the joints of the cement concrete base to the asphalt surface layer, improve the use performance of the asphalt pavement and prolong the service life of the asphalt pavement.
本发明公开了一种沥青路面抑制反射裂缝的复合结构及改造方法，涉及道路修护技术领域，其技术方案要点是，包括填充在接缝内的自流粘合剂；铺设在水泥混凝土基层上并将接缝完全覆盖的防裂层；覆盖在防裂层上并富有弹性的应力释放层，应力释放层上开设有多个与接缝长度方向相垂直的预留裂缝，各预留裂缝与接缝的位置相对应，每个预留裂缝内均填充有填料，填料在受压时会被挤爆并释放粘结物质；沥青混凝土面层铺设在应力释放层上。该种沥青路面抑制反射裂缝的复合结构及改造方法能够有效地防止或延缓水泥混凝土基层的接缝给沥青面层造成的反射裂缝，提高沥青路面的使用性能和寿命。
