A 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 water-permeable surface layer sequentially arranged from bottom to top; wherein, the water-permeable surface layer includes a water-permeable fiber structure and a structure composed of asphalt or concrete layer; the permeable fiber structure is a network structure woven from fiber material, and it is laid on the surface of the subgrade; the structural layer is poured in the grid formed by the permeable fiber structure; the part of the permeable fiber structure exposed on the surface of the structural layer is in the form of point clusters distribution to form water seepage inlet points; the water permeable fiber structure extends out of the structural layer along both sides of the road surface to form water seepage drainage points. The invention can make rainwater on the road surface enter the permeable fiber structure through the seepage water inlet point, and flow laterally to the water seepage drainage point to be discharged, thereby achieving better water permeability and drainage effects; it is economical and practical, and is suitable for mass promotion.

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...

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.
