Background

The asphalt pavement structure for airport runways is characterized by that various kinds of pavements made of asphalt material are mixed in mineral material, and the asphalt pavement can raise the ability of paving granules to resist running and damage of natural factors to pavement, and can make the pavement smooth, dustless, impervious and durable, so that it is a high-grade pavement which is most extensively used in road construction.

When current airport is bituminous paving structure for runway is using, because pitch class structural layer itself is the flexible pavement category, in the use, the round trip of aircraft is gone, makes the road surface receive the repeatability and rolls, and because the heavyweight problem of fuselage, makes the structure at road surface center expand to both sides with higher speed to cause road surface border local fracture, when maintaining the road surface that has been damaged, need demolish bold road surface together, then lay again, the engineering time is longer, and cost of maintenance is higher.

Disclosure of Invention

The invention mainly aims to provide an asphalt pavement structure suitable for an airport runway sectional splicing design, so as to solve the problem that the damaged airport runway is inconvenient to maintain in the prior art.

In order to achieve the purpose, the invention provides an asphalt pavement structure suitable for the sectional splicing design of an airport runway, which comprises a pavement and an asphalt surface layer arranged on the pavement, wherein a plurality of connecting plates are detachably arranged between the asphalt surface layer and the pavement, the connecting plates are arranged along the extending direction of the asphalt surface layer, the connecting plates are positioned at two sides of the asphalt surface layer, the connecting plates are clamped with the asphalt surface layer, and two adjacent connecting plates are clamped with each other.

Further, the pitch surface course lateral part is equipped with the standing groove, and the lateral part of connecting plate is equipped with the spread groove with the standing groove adaptation.

Further, the placing groove is arranged along the extending direction of the asphalt surface layer.

Furthermore, a limiting groove is formed in the placing groove, and a clamping strip matched with the limiting groove is arranged on the connecting groove.

Further, the limiting groove is arranged along the extending direction of the placing groove.

Furthermore, one end of the connecting plate is provided with a clamping block, and the other end of the connecting plate is provided with a clamping groove matched with the clamping block.

Furthermore, the lower part of the clamping block is provided with a bulge which is of a boss-shaped structure.

Furthermore, a cement gravel layer and a natural gravel layer are arranged below the asphalt surface layer.

Further, the surface of the asphalt surface layer is provided with a waterproof layer.

Furthermore, the corners of the connecting plate are provided with notches.

By applying the technical scheme of the invention, the plurality of connecting plates are detachably arranged between the asphalt surface layer and the pavement, the connecting plates are arranged along the extending direction of the asphalt surface layer, the connecting plates are positioned at two sides of the asphalt surface layer, the connecting plates are clamped with the asphalt surface layer, and the adjacent two connecting plates are clamped, so that the edge fracture caused by the expansion of the central structure of the asphalt surface layer to two sides is transmitted to the connecting plates, the damaged pavement can be conveniently and quickly repaired by detaching and replacing the connecting plates, and the problem that the damaged runway in the existing airport is inconvenient to repair is effectively solved.
