Permeable anti-cracking road structure and construction method thereof

Abstract

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.

Description

technical field [0001] The invention relates to road engineering in the field of traffic engineering, in particular to a water-permeable and crack-resistant road structure and a construction method thereof. Background technique [0002] With the rapid development of economic construction and the acceleration of urban construction, the surface of modern cities is gradually covered by reinforced concrete houses and impermeable pavement. In urban construction, the design and hardening of most urban roads, parks, courtyards and public squares mainly focus on technical performance indicators such as durability and strength and visual aesthetic requirements, so impermeable densely graded concrete and stone slabs Become the pavement structure of choice. Although this kind of paving is simple and low in cost, it has brought a great negative impact on the ecological environment of the city. [0003] First of all, this impermeable and airtight pavement significantly reduces the rain...
