Reflection-crack-free semi-rigid base pavement structure and construction method thereof
The invention belongs to the technical field of road and bridge construction, and particularly relates to a reflection-crack-free semi-rigid base pavement structure and a construction method thereof. The technical key points are as follows: the floor comprises a semi-rigid base layer, a lower surface layer, a middle surface layer and an upper surface layer from bottom to top; wherein the semi-rigid base layer is provided with a pre-cutting seam, and the lower surface layer is provided with a flexible splicing deformation seam; the flexible splicing deformation joint is arranged right above the pre-cutting joint, and the part larger than the pre-cutting joint is bilaterally symmetrical relative to the pre-cutting joint, so that the base layer is pre-cut; and polyester glass fabric is adhered to the surface of the pre-cutting seam. According to the reflection-crack-free semi-rigid base pavement structure and the preparation method thereof, the pre-cutting joints are formed in the semi-rigid base, so that disordered cracks become regular, and the high-elasticity and high-toughness asphalt poured into the pre-cutting joints has certain deformability and can absorb deformation caused by bottom layer cracking.
本发明属于道桥施工技术领域，具体涉及一种无反射裂缝半刚性基层路面结构及其施工方法。其技术要点如下：从下到上包括，半刚性基层，下面层，中面层和上面层；其中，半刚性基层上设置有预切缝，下面层上设置有柔性拼接变形缝；柔性拼接变形缝设置于预切缝的正上方，且大于预切缝的部分相对于预切缝左右对称以使得基层预切缝；所述预切缝表面粘贴聚酯玻纤布。本发明的提供一种无反射裂缝的半刚性基层路面结构及其制备方法，通过在半刚性基层中设置预切缝使得无序的开裂变得有规则，预切缝内灌注高弹高韧沥青具有一定的变形能力，能够吸收底层开裂引起的变形。
