Permeable asphalt pavement structure with protective measures

Abstract

The invention discloses a permeable asphalt pavement structure with protective measures, which comprises a pavement body, guide strips are arranged on the pavement body, anti-collision ridges are arranged at the edge of the pavement body, and the pavement body consists of Arranged surface course, cushion course, filter layer, shock-absorbing layer and soil base; the surface course includes fine-grained permeable asphalt mixture surface layer arranged above and medium-grained type permeable asphalt mixture surface layer below, so A blind drainage pipe is provided in the cushion layer, and the blind drainage pipe is located at one end directly below the medium-grain permeable asphalt mixture surface layer. While realizing the permeable function of the motorway, it also meets the road performance; it solves the problem of the existing permeable pavement due to structural combination design defects, resulting in poor bearing capacity and short life cycle of the fully permeable pavement , unable to withstand large traffic loads and other problems; and has the functions of guidance and collision avoidance.

Description

technical field [0001] The invention relates to the field of public pavements, in particular to a permeable asphalt pavement structure with protective measures. Background technique [0002] The concept of sponge city was put forward at the end of 2013, which requires the city to be like a sponge and have good "elasticity" in adapting to environmental changes and responding to natural disasters. The water is "released" and used. In October 2015, the General Office of the State Council's "Guiding Opinions on Promoting the Construction of Sponge City" (Guo Ban Fa [2015] No. 75) required that by 2030, more than 80% of the urban built-up area should be covered, and 70% of the rainfall should be absorbed locally and exploit the target requirements. With the advancement of sponge city construction, fully permeable pavement structures are limited to large-area applications of light-load pavement such as squares, sidewalks, gardens, and non-motor vehicle lanes. The main pavement g...

Problems solved by technology

[0005] Based on this, in view of the above problems, it is necessary to propose a permeable asphalt pavement structure with protective measures, which not only realizes the permeable function of motor vehicle lanes, but also meets the road performance; solves the problem of existing permeable pavement pavement Due to structural combination design defects, the fully transparent pavement has poor bearing capacity, short life cycle, and inability to bear large traffic loads; and it has the functions of guiding and anti-collision
