Problems solved by technology

[0002] At present, the traditional pavement repair process is too random and simple. It does not pay enough attention to the pretreatment and advanced treatment of the road surface. The degree of treatment is not rigorous enough. The indicators required for the pavement caused the repaired pavement to still fall off, crack or be damaged shortly after use. The traditional repair process obviously failed to achieve the repair effect, resulting in a waste of manpower, material and financial resources. At the same time, it also caused Secondary damage to the pavement

Embodiment Construction

[0021] Below in conjunction with embodiment the present invention is further described in detail.

[0022] Such as figure 1 Shown, a kind of repair process of road or bridge pavement is characterized in that: comprise the following steps:

[0023] (1) Removing the carbonized layer: use grinding equipment to grind the hot-pressed pavement, remove the carbonized layer on the surface, and find hidden diseases on the pavement;

[0024] (2) Excavation: find the damaged part on the road surface, and hide the diseased part, delineate the damaged area, use a cutting machine to cut out the damaged area, dig out the damaged pavement material, and form a neat groove. The depth of the groove must be strictly guaranteed 2- 20cm; Among them, the groove depth must be strictly guaranteed. For non-structural repairs, the groove depth depends on the damage depth of the road surface. For structural repairs, the groove depth depends on the overall road damage depth. The conventional road surface...

Abstract

The invention discloses a repairing process of road or bridge pavements. The process comprises the following steps: (1) removing a carbonized layer; (2) excavating; (3) removing waste materials; (4) applying a bottom glue layer; (5) filling sand pulp; (6) removing the carbonized layer. Compared with the prior art, the process has the advantage of being meticulous, the degree of bonding between a repaired part and an original pavement is high, falling, cracking or breaking is avoided, the pavements are firm and durable, and the service life of roads or bridges is remarkably prolonged.

Description

technical field [0001] The invention relates to a pavement repairing process, in particular to a road or bridge pavement repairing process. Background technique [0002] At present, the traditional pavement repair process is too random and simple. It does not pay enough attention to the pretreatment and advanced treatment of the road surface. The degree of treatment is not rigorous enough. The indicators required for the pavement caused the repaired pavement to still fall off, crack or be damaged shortly after use. The traditional repair process obviously failed to achieve the repair effect, resulting in a waste of manpower, material and financial resources. At the same time, it also caused Secondary damage to the pavement. Contents of the invention [0003] In order to solve the above-mentioned deficiencies of the prior art, the present invention provides a road or bridge pavement repair process. [0004] Above-mentioned purpose of the present invention is achieved by f...
