Fiber implanted permeable pavement structure

Abstract

The invention discloses a fiber implanted permeable pavement structure which comprises a rammed earth layer, a roadbed and a permeable surface layer which are sequentially arranged from bottom to top,wherein the permeable surface layer comprises a permeable fiber structure and a structural layer consisting of asphalt or concrete; the permeable fiber structure is of a net structure formed by weaving fiber materials and is laid on the surface of a roadbed. The structural layer is poured in a grid formed by the permeable fiber structure; the parts, exposed out of the surface of the structural layer, of the permeable fiber structure are distributed in a point cluster manner to form water seepage inlet points; the permeable fiber structure extends out of the structural layer along the two sides of the pavement to form water seepage and drainage points. Rainwater on a road surface can enter the permeable fiber structure through the water seepage inlet points and laterally flow to the waterseepage drainage points to be discharged, and better permeable and water outlet effects can be achieved; the structure is economical, practical and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of pavement structures, in particular to a fiber-implanted water-permeable pavement structure. Background technique [0002] With the development of the times, the road performance limitations of traditional impermeable pavements are becoming more and more obvious. Traditional urban roads are mostly paved with asphalt mixture or cement concrete, which do not have water permeability, and the drainage is realized by the transverse slope of the road arch. Excessive drainage or blockage in the rainy season may cause water accumulation on the road. The impermeable pavement cannot discharge the accumulated water within the scope of use in time, which not only hinders the normal driving of vehicles, but also seriously affects the road performance of the road. For example, aggregate segregation and asphalt spalling will occur on asphalt pavement under the action of water for a long time, which will cause road surfa...

AI Technical Summary

Problems solved by technology

At present, permeable pavement designs mostly use permeable materials such as permeable asphalt and permeable concrete to achieve the infiltration and drainage effects of accumulated water, but their cost is high and they are not suitable for mass promotion.
