Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: due to the irregular shape and small width of the cracks, the above-mentioned technical solutions are used to repair the cracks, and the asphalt pavement around the cracks needs to be cleaned in a large area before repairing. Excavating repair grooves and V-shaped grooves will cause great damage to the road surface, the repair structure is complicated, it takes a long time, and it is difficult to ensure the integrity of the repaired road surface

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , is a damaged asphalt pavement repair structure disclosed in the present invention, including repair grooves arranged along the crack extension direction and filling structures filled in the repair grooves, the filling structure is connected to the original pavement layer 100, and the upper surface and the pavement surface layer flush.

[0042] The repair groove is a groove opened along the extension direction of the crack. The groove body of the repair groove has the same opening depth along the length direction, including the V-shaped groove 1 formed by digging the crack at the bottom and the one set on the top of the V-shaped groove 1 to expand and excavate to both sides. Step groove 2, the side surfaces on both sides of the step groove 2 are symmetrically arranged along the central axis of the V-shaped groove 1, and the distance b...

Abstract

The invention relates to a repair structure for damaged asphalt pavement, and relates to the technical field of road maintenance, comprising repair grooves arranged along the crack extension direction and filling structures filled in the repair grooves, the filling structure is connected to the original pavement layer; The repair groove includes a V-shaped groove with a crack dug at the bottom and a stepped groove extending to both sides at the top of the V-shaped groove, and the stepped groove extends to the surface of the road surface; the filling structure includes a potting glue filled in the V-shaped groove Layers, flexible slabs arranged in each layer of stepped grooves, and asphalt filling layers filled in each layer of flexible slabs, the flexible slabs are fixed on the original pavement layers on the two walls of the stepped grooves by rigid rivets. The repairing structure of the invention can reduce the damage to the surrounding pavement structure layer in the process of repairing cracks, improve the integrity and durability of the pavement after repairing, and shorten the construction period.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a damaged asphalt pavement repair structure and repair process. Background technique [0002] Asphalt pavement has the advantages of low cost, low noise, comfortable driving, fast construction and convenient maintenance, so asphalt pavement has been widely promoted and applied. After the asphalt pavement is completed, various gaps will gradually form and expand due to the influence of traffic load, environmental factors, pavement materials and structures, and as time goes by. After the gap is formed, rainwater enters the base layer through the gap, forming dynamic water to scour the structural layer, and finally causing cracks, potholes and other phenomena on the road surface. The appearance of gaps not only damages the continuity and flatness of the road surface, affects the aesthetics of the road surface and driving comfort, but also easily causes water to erode the r...
