Road intersection height anti-deformation pavement structure and method
The invention discloses a road intersection height anti-deformation pavement structure and method in the technical field of road engineering pavement structures, and aims to solve the technical problems that a road intersection is prone to rut deformation and low in structural durability. The pavement structure is composed of a high-cohesiveness asphalt micro-overlay wearing layer, a high-strengthrigid-flexible composite material upper surface layer, a high-modulus asphalt middle surface layer, a modified asphalt lower surface layer and a cement stabilized macadam semi-rigid base layer from top to bottom, the surface layers are connected through modified emulsified asphalt bonding layers, and a high-elasticity asphalt stress absorption layer is laid between the surface layers and the baselayer. The pavement structure has high deformation resistance, long service life and high driving safety and comfort; meanwhile, only the wearing layer needs to be maintained in daily life, the method has the advantages of rapidness and convenience, the influence on traffic can be reduced to the maximum extent, and the use quality of the pavement can be kept.
本发明公开了道路工程路面结构技术领域的一种道路交叉口高度抗变形路面结构和方法，旨在解决道路交叉口易出现车辙变形、结构耐久性低的技术问题。所述路面结构从上至下由高粘聚性沥青微罩面磨耗层、高强度刚柔复合材料上面层、高模量沥青中面层、改性沥青下面层、水泥稳定碎石半刚性基层组成，面层之间采用改性乳化沥青粘层连接，面层和基层之间铺设高弹性沥青应力吸收层。所述路面结构具有高度抗变形能力，路面结构使用寿命长，行驶安全性和舒适性高；同时，日常只需要对磨耗层进行养护，具有快速、便捷的优点，可最大限度的降低对交通的影响，并有利于保持路面的使用品质。
