White-to-black pavement reflection crack prevention and treatment structure and construction method thereof
The invention discloses a white-to-black pavement reflection crack prevention and treatment structure and a construction method thereof. The prevention and treatment structure comprises a backfill material layer, a waterproof bonding layer, a fiber cloth layer and an asphalt tackifying waterproof layer which are sequentially laid on the surface of a cement concrete base layer from bottom to top. Joints and cracks on the surface of the base layer are filled with the backfill material layer, the surface of the backfill material layer and the surfaces of the base layers on the two sides are coated with the waterproof bonding layer, and the fiber cloth layer is bonded to the surface of the waterproof bonding layer; and the asphalt tackifying waterproof layer is coated on the surface of the fiber cloth layer and is bonded with the asphalt overlay layer. The backfill material layer has the effects of filling base layer crack joints, supporting the asphalt overlay, dispersing stress, preventing water and the like, and the strength difference between the backfill material layer and the base layer can be reduced; through the synergistic effect of the fiber cloth layer, the waterproof bonding layer and the asphalt tackifying layer, the influence of deformation of base layer joints and cracks on the asphalt overlay can be reduced, reflection cracks are prevented or delayed, and the asphalt overlay has the advantages of being easy and convenient to construct, high in cost performance and the like and is wide in application range.
本发明公开一种白改黑路面反射裂缝防治结构及其施工方法，该防治结构包括自下而上依次铺设于水泥混凝土基层表面的回填料层、防水粘结层、纤维布层和沥青增粘防水层；回填料层填充于基层表面的接缝、裂缝中，防水粘结层涂设于回填料层的表面和两侧基层表面，纤维布层粘合于防水粘结层的表面；沥青增粘防水层涂设于纤维布层的表面，与沥青罩面层粘结。回填料层具有填充基层裂缝接缝、支撑沥青罩面层和分散应力、防水等作用，可减小回填料层和基层之间的强度差；纤维布层与防水粘结层、沥青增粘层的协同作用，可减少基层接缝、裂缝处的变形对沥青罩面层的影响，防止或延缓反射裂缝产生，具有施工简便、性价比高等优点，适用范围广。
