Permeable anti-cracking road structure and construction method thereof
The invention discloses a water-permeable anti-cracking road structure and a construction method thereof. The water-permeable anti-cracking road structure sequentially comprises a water-permeable abrasion layer surface layer, a geocell open graded broken stone water-permeable cement concrete upper base layer, a geocell medium-coarse sand lower base layer, a geocell plain soil subbase layer and a roadbed from top to bottom. The pocket constraint effect of the geocell enables the soil composite elasticity modulus of the geocell to be increased exponentially, and meanwhile, the lateral deformation of the roadbed and the generation and development of cracks can be powerfully limited; and the thick plate effect generated by overlapping the three geocell structure layers guarantees that the roadbed has enough bending rigidity so as to reduce differential settlement of the road surface. The road structure belongs to a permeable pavement, has the advantages of environmental friendliness, modular design, convenience and quickness in construction, low construction cost and the like, can effectively avoid pavement cracks, high-temperature ruts and other diseases, and greatly enhances the driving safety and driving comfort in rainy days. The road structure and the method are suitable for various urban roads, grade highways, sports fields, squares, runways and other projects.
本发明公开了一种透水抗裂型道路结构及其施工方法，自上而下依次为透水磨耗层面层、土工格室开级配碎石透水水泥混凝土上基层、土工格室中粗砂下基层、土工格室素土底基层和路床。土工格室的口袋约束效应使得格室土复合弹性模量呈现指数级增长，同时会强力限制路基的侧向变形和裂缝的产生和发展；而三层土工格室结构层叠加产生的厚板效应则保证路基有足够的弯曲刚度以减少路面的不均匀沉降。该道路结构属于型透水路面，具有对环境友好、模块化设计、施工方便快捷、工程造价低等优点，可以有效杜绝路面裂缝和高温车辙等病害的产生，大幅增加雨天行车安全及行车舒适性。本发明适用于各类城市道路、等级公路、运动场地、广场、飞机跑道等工程。
