Roadbed and pavement reinforced structure combination suitable for desert area and construction method
The invention relates to a roadbed and pavement reinforced structure combination suitable for a desert area and a construction method, and belongs to the technical field of road construction. The roadbed and pavement reinforced structure combination suitable for the desert area comprises a cement-stabilized aeolian sand layer which is composed of the following materials in percentage by weight: 4-8% of cement, 34-66% of aeolian sand and 12-24% of coal ash; the first reinforced layers are two-way plastic geogrids and are arranged on the upper portion, the middle portion and the lower portion of the roadbed; and the second reinforced layer is a double-twisted steel wire reinforced net and is arranged at the bottom of the cement stable aeolian sand layer. The road structure has the beneficial effects that the road structure can help the roadbed to share stress strain transmitted by the road surface, so that the bearing capacity of the roadbed is improved, local loads are diffused, the bending-tensile strength and the crack resistance of the road surface structure are enhanced, road surface reflection cracks and structure internal micro cracks generated due to overlarge loads and large temperature differences are reduced, and the road quality is improved. And the anti-rutting performance is very good.
本发明涉及一种适用于沙漠地区路基路面加筋结构组合及施工方法，属于道路施工技术领域。适用于沙漠地区路基路面加筋结构组合，包括：水泥稳定风积沙层，由以下材质重量百分比的组分组成：水泥4％‑8％、风积沙34％‑66％和粉煤灰12％‑24％；第一加筋层，所述第一加筋层为双向塑料土工格栅，其设置在路基上、中、下部；第二加筋层，所述第二加筋层为双绞合钢丝加筋网，其设置在所述水泥稳定风积沙层的底部。有益效果：该道路结构能够帮助路基分担由路面传递而来的应力应变从而提高路基的承载能力，扩散局部荷载、增强路面结构的弯拉强度，抗裂性能，减少由于荷载过大以及温度差异较大而产生的路面反射裂缝、结构内部微裂缝，并且具有很好的抗车辙性能。
