Anti-rut pavement paving method capable of continuously paving base layer and surface layer
The invention discloses an anti-rut pavement paving method capable of continuously paving a base layer and a surface layer, and belongs to the field of road engineering. The method is characterized inthat a super-early-strength anti-cracking cement stabilized macadam base layer is paved firstly, and after the base layer is rolled, a cold-mixed cold-paved rigid-flexible composite surface layer ispaved under the condition that the surface is still in a wet state. Compared with the prior art, according to the anti-rut pavement paving method capable of continuously paving the base layer and thesurface layer, continuous paving of the cement stabilized macadam base layer and the surface layer can be realized; maintenance time for 7 days of the cement stabilized macadam base layer can be omitted, meanwhile, the continuity of the base layer and the surface layer is improved, the overall cooperative stress of the pavement structure is guaranteed, a permeable layer and a macadam sealing layerdo not need to be sprayed on the surface of the cement stabilized macadam base layer, and the construction cost is reduced. Meanwhile, the cold-mixed and cold-paved rigid-flexible composite surface layer does not need centralized hot mixing, so that construction is convenient, resources are saved, and the environment is protected. The anti-rutt pavement structure with the base layer and the surface layer capable of being continuously paved has high high-temperature anti-rutting performance, anti-cracking performance, water stability and durability, and has high popularization and applicationvalues.
本发明公开了一种基层、面层可连续摊铺的抗车辙路面铺装方法，属于道路工程领域。其特点是先铺筑超早强抗裂型水泥稳定碎石基层，在基层碾压完成后，表面仍潮湿状态下摊铺冷拌冷铺型刚柔复合面层。与现有技术相比，本发明的基层、面层可连续摊铺的抗车辙路面铺装方法可实现水泥稳定碎石基层与面层的连续摊铺，节省水泥稳定碎石基层七天养护时间的同时，提高基层与面层的连续性，保证路面结构整体协同受力，且不需在水泥稳定碎石基层表面喷洒透层和撒布碎石封层，降低施工成本。同时，冷拌冷铺型刚柔复合面层不需集中热拌，施工方便，节约资源，保护环境。基层、面层可连续摊铺的抗车辙路面结构具有良好的高温抗车辙性能、抗裂性能、水稳定性和耐久性，具有很好的推广应用价值。
