Anti-crack roadbed pavement structure and construction method thereof
The invention discloses an anti-crack roadbed pavement structure and a construction method thereof. The pavement structure sequentially comprises an asphalt mixture wearing layer and a geogrid from top to bottom; the upper layer of the roadbed structure is geocell solidified soil, the lower layer of the roadbed structure is at least one layer of geocell plain soil and compacted plain soil interbedded layer, and a roadbed which is leveled and compacted to meet the standard requirement is arranged below the roadbed structure. The lateral constraint effect of the geocell limits the lateral deformation of the roadbed and the pavement and the generation and development of cracks, and the flexural rigidity of the roadbed can be greatly improved by a thick plate effect generated by the soil of the multiple layers of geocells, so that the differential settlement of the pavement is reduced, and the driving comfort is improved. The road structure has the advantages of being modular in design, convenient to construct, environmentally friendly, good in water stability, low in manufacturing cost, high in high-temperature rut resistance, high in bearing capacity and the like, can effectively eradicate pavement cracks, permanent deformation and other diseases, greatly prolongs the service life of engineering, and is suitable for various grades of roads, urban roads, sport fields, large-area storage yards, runways and other engineering.
本发明公开了一种抗裂路基路面结构及其施工方法，路面结构自上而下依次为沥青混合料磨耗层+土工格栅；路基结构上层为土工格室固化土，下层为至少一层的土工格室素土与压实素土互层，其下为经过平整压实达到规范要求的路床。本发明土工格室的侧向约束效应限制了路基路面侧向变形和裂缝的产生和发展，多层土工格室土产生的厚板效应能大幅度提高路基的抗弯刚度，从而减少路面的不均匀沉降，增加行车舒适性。该道路结构具有设计模块化、施工方便、环保、水稳定性好、造价低、抗高温车辙能力强、承载力高等优点，可以有效杜绝路面裂缝和永久变形等病害的产生，大幅增加工程的服役寿命，适用于各种等级公路、城市道路、运动场地、大面积堆场、飞机跑道等工程。
