Technical Field

The invention belongs to the technical field of pavement structures and construction, and particularly relates to an anti-skid pavement structure and a construction method thereof.

Background

In recent years, due to the rapid increase of overload vehicles, heavy-duty vehicles and traffic flow, although most of roads built in early stage have complete pavement structure, the performances of pavement skid resistance, flatness, comfort and the like are greatly reduced, and some roads even cannot meet the use requirements, so that great potential safety hazards exist.

At present, the original asphalt mixture pavement layer and the asphalt concrete overlay are firmly bonded together by bonding materials between the asphalt concrete overlay layers of the existing pavement structure, the pavement of the structure has large paving thickness and poor durability, and after a long time, the anti-skid particles on the surface can generate interlayer shift damage under the action of vehicle load, so that the service life of the pavement is shorter, the anti-skid performance is seriously damaged, and the vehicle running noise is also larger.

Disclosure of Invention

The invention aims to provide an anti-skid pavement structure and a construction method thereof, which improve the stability between the anti-skid pavement structure and the structure by improving the stability and the load damage resistance of an adhesive layer, ensure the performance and the structural stability of the anti-skid pavement, and prolong the service life so as to solve the problems in the background art.

The invention is realized by the following technical scheme:

The anti-skid pavement structure comprises a road base layer, a bonding layer and an anti-skid layer which are sequentially laid from bottom to top, wherein a grid net is arranged between the road base layer and the bonding layer, and chopped carbon fibers which are uniformly and disorderly distributed are laid in the bonding layer.

further, the bonding layer comprises the following components in parts by weight: 100-250 parts of epoxy resin adhesive, 3-5 parts of anti-stripping agent, 20-30 parts of warm mixing agent and 3-5 parts of anti-rutting agent.

further, the grid net is a stainless steel plate strip-shaped grid net or a stainless steel net plate-shaped grid net.

Further, the length of the chopped carbon fibers is 20-45mm, the diameter of each monofilament is 10-20 um, and the mass content of the chopped carbon fibers in the bonding layer is 30-40%.

Further, the anti-slip layer is made of basalt mineral aggregates with the Mohs hardness of more than 6 and the grinding value of more than 60.

Furthermore, the roadbed layer is an asphalt roadbed or a cement concrete roadbed.

A construction method of an anti-skid pavement structure mainly comprises the following steps:

When a cement concrete roadbed layer or an asphalt roadbed layer is laid, a layer of grid net is laid on a road surface, battens of the grid net are bundled by steel wires, and the area of a grid net is 1-1.5 square meters; then laying cement concrete or asphalt, and exposing one section of the grid net outside, wherein the exposed height is 15-30 mm;

Spreading the mixture of the components of the bonding layer on the road base layer, uniformly and disorderly spreading the chopped carbon fibers on the surface of the bonding layer when the thickness of the bonding layer reaches 5-10mm, and continuously spreading the bonding layer until the thickness reaches 35-40mm to finish the laying of the bonding layer;

Immediately paving the crushed and screened basalt ore granules with the grain size not larger than 1.5mm when the paving of the bonding layer is finished, and curing and maintaining for 5-7 days at normal temperature after the paving is finished to finish the construction.

the invention has the following beneficial effects:

the invention ensures that the road base layer and the bonding layer are stably connected through the grid net structure, improves the comprehensive performance of the bonding layer through the chopped carbon fibers, and improves the load damage resistance and the granule peeling resistance in all directions, thereby improving the stability among structures, preventing the interlaminar transition damage, ensuring the performance and the structural stability of the antiskid pavement, and prolonging the service life of the pavement.
