Composite highway silty-fine sand roadbed structure and construction method
The invention discloses a composite highway silty-fine sand roadbed structure and a construction method, and relates to the technical field of road construction. Comprising multiple silty-fine sand core filling layers laid on a foundation, soil filling isolation layers are laid among the multiple silty-fine sand core filling layers at intervals, lateral confinement enhancement layers are arranged on the outer sides of the silty-fine sand core filling layers, and a performance improvement layer, a strength compensation layer and a pavement structure layer are sequentially arranged above the uppermost silty-fine sand core filling layer. The technical problems that a vibratory roller for silty-fine sand roadbed construction cannot conduct rolling compaction, the compaction quality is difficult to guarantee, the water demand of a watertight method is large, and large-scale roadbed construction is not suitable can be solved, cracking, collapsing and the like of the silty-fine sand roadbed pavement along the contact face of the edge covering soil and the sand core are avoided, the service life of the roadbed pavement is prolonged, and the road surface driving comfort is improved.
本发明公开了一种复合式公路粉细砂路基结构及施工方法，涉及道路建设技术领域。包括铺设在地基上的多层粉细砂填芯层，多层粉细砂填芯层之间的间隔铺设有填土隔离层，粉细砂填芯层外侧设置有侧限增强层，最上方的粉细砂填芯层的上方依次设置有性能提升层、强度补偿层和路面结构层。本发明可解决粉细砂路基施工振动压路机无法碾压，压实质量难保证，水密法需水量大、不适宜进行路基大规模施工的技术难题，避免粉细砂路基路面沿包边土和砂芯接触面的开裂、湿陷等，实现路基路面的延寿，提升路面行车的舒适性。
