Ecological drainage pavement

Abstract

The invention discloses an ecological drainage pavement, and relates to the technical field of pavement construction. The ecological drainage pavement comprises a fine sand layer, the top of the fine sand layer is paved with a first stone layer, the top of the first stone layer is paved with a bottom filling layer, the top of the bottom filling layer is paved with an asphalt macadam layer, the top of the asphalt macadam layer is provided with a connecting plate, a limiting block is mounted at the top of the connecting plate. The top filling layer has certain viscosity, the bottom of the top filling layer can be reinforced through the connecting plate and the limiting block, the situation that the interior of the pavement cracks due to the pressure borne by the top of the pavement is avoided, finally through connection between a second stone layer with the small size and the asphalt layer, the pavement is smoothened; and the asphalt layer at the top is arc-shaped, so that water at the top of the pavement can be discharged to two sides, the situation of water accumulation is avoided, and the situation that the water is splashed to pedestrians in the vehicle driving process is avoided.

Description

technical field [0001] The invention belongs to the technical field of pavement construction, and in particular relates to an ecological drainage pavement. [0002] technical background [0003] A layered structure that is paved on the roadbed with road construction materials for vehicles to run on. It has the functions of bearing the weight of the vehicle, resisting wheel wear and keeping the road surface smooth. For this reason, the road surface is required to have sufficient strength, high stability, certain flatness, appropriate anti-skid ability, and no excessive dust phenomenon when driving, so as to reduce damage to the road surface and vehicle parts and maintain good visibility. distance and reduce environmental pollution. Pavement is divided into rigid pavement and flexible pavement according to its mechanical characteristics. [0004] However, in the prior art, the existing pavement is prone to cracking and collapse at the top of the pavement due to insufficient ...

Problems solved by technology

[0004] However, in the prior art, the existing pavement is prone to cracking and collapse at the top of the pavement due to insufficient use of internal materials, which in turn leads to cracking of the pavement, causing water to enter the interior of the pavement, further eroding the internal structure of the pavement, and reducing the The drainage effect of the pavement
