Problems solved by technology

However, when subjected to wheel load stamping, weather changes, and crack expansion, the asphalt and other repair materials that seal the cracks are prone to aging, cracking, and even falling off from the cracks, causing water to enter the cracks and causing damage to roads and bridges

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the embodiments.

[0012] A construction method for sealing and repairing road cracks with anti-detachment and anti-cracking, comprising the following steps:

[0013] a. Paint the crack 1 with a solvent 2 that can fuse both dust and asphalt to eliminate the bond between the material and the crack that affects the sealing and repairing of the crack;

[0014] b. Sprinkle high-strength fibers 3 of suitable length and size on the crack surface. The longitudinal direction of most fibers should intersect with the crack direction, and overlap each other or form a network structure;

[0015] c. Fill the cracks with asphalt or polymer sizing material, or paste the tape-shaped sealing and repairing material 4, (the fibers and the sealing and repairing material are automatically bonded together), and spread suitable sand particles.

[0016] Steps b and c can be performed in reverse, that is, first pour asph...

Abstract

The invention relates to a construction method for preventing a repaired crack from cracking, which relates to the construction process for blocking and repairing a crack. The method comprises the following steps of: a, painting a solvent which can merge both dust and asphalt on the crack so as to eliminate the influence on the adhesion between a material for blocking and repairing the crack and the crack; b, spraying high-strength fibers with proper lengths and sizes on the crack, wherein the longitudinal direction of most of the fibers and the trend of the crack are intersected to be mutually overlapped or form a meshed structure; and c, pouring the asphalt or a macromolecular sizing material into the crack, or sticking a band-shaped repairing material to ensure that the fibers and the material for blocking and repairing the crack are automatically adhered together. In the construction method, the coated solvent merges loose dust on the crack as well as the asphalt on the surface layer of the crack, so that the repairing material is prevented from being separated from a crack layer; the sprayed fibers and the trend of the crack are intersected to be mutually overlapped or form the meshed structure; and the repairing material is adhered to the merged fibers, thus the crack can be blocked and repaired so as to form a high-retractility and low-temperature cracking-resistant road surface.

Description

technical field [0001] The invention relates to a construction method for preventing cracks after repairing. Background technique [0002] Cracks appear in roads and bridges for various reasons. If these cracks are not dealt with in time, after rainwater enters the cracks, under the action of vehicle load, it will accelerate the damage to roads and bridges, and shorten the service life of pavements and bridges. [0003] In order to prevent water from entering the cracks, it is necessary to seal and repair the cracks that appear. Although there are many construction methods for closing the cracks, such as pouring asphalt into the cracks, or coating asphalt on the crack surface, or sticking strips on the crack surface. Repair material that can seal cracks and prevent rainwater from entering the cracks. However, when subjected to wheel load, weather changes and crack expansion, the above-mentioned repair materials such as asphalt that seal the cracks are prone to aging, crack...
