Water-stable layer, road structure and construction method of water-stable layer
The invention discloses a cement stable layer, a road structure and a construction method of the road structure, and relates to the technical field of road construction. A water stabilizing layer comprises a first geogrid layer, a first cement stabilized macadam layer, a second geogrid layer and a second cement stabilized macadam layer which are sequentially arranged from bottom to top. The geogrid layer is arranged and used for forming interface bonding force and physical occlusal force between the geogrid layer and the cement stabilized macadam layer, and when the cement stabilized macadam layer shrinks and deforms due to the influence of the load, the cement stabilized macadam layer can deform; the interface bonding force and interlocking effect between the geogrid layer and the cement stabilized macadam layer can hinder horizontal relative displacement between the cement stabilized macadam layer and the geogrid layer, shrinkage deformation of the cement stabilized macadam layer is reduced, and therefore the water stable layer forms a stable base layer structure. Therefore, compared with the prior art, the non-deformability of the water-stable layer is improved, cracking of the water-stable layer is reduced, and the later maintenance cost is reduced.
本申请公开了一种水稳层、道路结构及其施工方法，涉及道路施工技术领域。一种水稳层，包括从下向上依次设置的第一土工格栅层、第一水泥稳定碎石层、第二土工格栅层和第二水泥稳定碎石层。本申请通过设置土工格栅层，用于在土工格栅层与水泥稳定碎石层之间形成界面粘接力和物理咬合力，当水泥稳定碎石层受载荷影响而收缩变形时，土工格栅层与水泥稳定碎石层之间的界面粘接力和嵌锁作用会阻碍水泥稳定碎石层与土工格栅层之间发生水平的相对位移，减小水泥稳定碎石层的收缩变形，从而使得水稳层形成一个稳定的基层结构。因此，与现有技术相比，本申请提高了水稳层的抗变形能力，减少了水稳层的开裂，降低了后期维护成本。
