Water-permeable and energy-absorbing asphalt pavement structure and laying method thereof

Abstract

The invention discloses a permeable and energy-absorbing asphalt pavement structure, which comprises from bottom to top: a pavement base, an impermeable layer, a filter layer, a support and an asphalt pavement layer; a drainage ditch is arranged in the pavement base, and the top of the drainage ditch is arranged There is a permeable hole plate cover; the impermeable layer is horizontally inclined, and the lowest end of the impermeable layer is connected to the top of the drainage ditch, and the highest end is connected to the end of the support; the support includes a horizontal top plate and a vertical support plate, and the vertical support The plate is connected to the permeable orifice cover. Also disclosed is a laying method for the above-mentioned water-permeable and energy-absorbing asphalt pavement structure. The water-permeable and energy-absorbing asphalt pavement structure of the present invention restricts the fluidity of the filter layer by setting brackets, improves the water permeability of the pavement, and enhances the overall strength of the pavement. Moreover, the steel wire mesh is embedded in the asphalt pavement layer to improve the strength of the pavement; the leaking pipe is inserted into the asphalt pavement layer to make the water permeated into the asphalt pavement flow downward more quickly and improve the water permeability of the pavement.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement, in particular to a water-permeable and energy-absorbing asphalt pavement structure and a laying method thereof. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. [0003] Therefore, the existing asphalt pavement has low structural strength, is easy to wear and tear, has poor anti-skid effect, and has a single c...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the existing asphalt pavement structure strength is low, easy to wear and tear, the anti-skid effect is also poor, the color tone is relatively single, the filter layer in the asphalt pavement is easy to follow the flow of water, resulting in the problem of unstable pavement
