Problems solved by technology

If it is not treated in time, the disease will continue to deteriorate. When the rut reaches a certain depth, it will reduce the smoothness of the road surface and affect the traffic performance
Moreover, when water accumulates in the rut after rain, it is very easy for the vehicle to drift, which seriously threatens driving safety.
Moreover, the existing asphalt composite pavement has no self-healing ability after damage, and once damaged, it needs to be rebuilt

Embodiment Construction

[0025] The asphalt pavement structure and laying method of the present invention will be further described with reference to the accompanying drawings.

[0026] as attached figure 1 As shown in , the asphalt pavement structure includes cement concrete base (3), asphalt concrete pavement layer (2) and the uppermost reinforcement mesh (1); the cement concrete base (3) and asphalt concrete pavement layer (2) are paved by conventional roads Concrete material is used; the reinforcement mesh (1) is a flexible steel rope grid, which is braided by steel wire ropes with a diameter of 6mm, and the mesh is a prismatic hole of 10cm×10cm. When the area of ​​a single reinforcement mesh is insufficient, multiple reinforcement meshes are used to splice; the interface is connected with the same material and size as the mesh mesh according to the mesh weaving specifications.

[0027] The construction method of adding reinforcement mesh asphalt pavement mainly includes the following steps:

Abstract

The invention discloses an asphalt pavement additionally laid with a rib net and belongs to the technical field of road construction. The asphalt pavement additionally laid with the rib net structurally comprises a cement concrete base layer and an asphalt concrete pavement layer. The asphalt pavement is further provided with the rib net, wherein the rib net is flatly laid on the upper side of the asphalt concrete pavement layer and embedded into the upper surface layer of the asphalt concrete pavement layer to make the pavement flat wholly, and net ropes of the rib net and the road form angles of 20-40 degrees. The asphalt pavement is additionally laid with the rib net to form a whole structure, the rib net forms a transverse prestressing force, the transverse pushing-extruding effect of tire pressures on the pavement is reduced, and track damages are greatly reduced. In addition, a load is effectively dispersed, the anti-cracking performance and anti-impact performance of the asphalt pavement are improved, accordingly the durability of the pavement is improved, and the service life of the road is prolonged.

Description

technical field [0001] The invention specifically relates to an asphalt pavement with reinforced mesh, which belongs to the technical field of road construction. Background technique [0002] With the rapid development of society, the requirements for roads also rise accordingly. Cement concrete pavement has the advantages of mature technology, high strength, and strong load capacity, but it has poor driving comfort and insufficient durability. A large number of cement concrete pavements will face maintenance and reconstruction, including the overall damage of the cement concrete pavement built in the early days after the end of its service life, which seriously affects the use of roads; and with the increase in traffic volume and increasingly heavy load, the cement concrete pavement built recently is open to traffic Different degrees of local structural damage will also appear in a short period of time afterward. [0003] The currently recognized improvement measure is ...
