Abstract

The invention relates to a treatment process for high-grade road surface crack. Said treatment process includes the following steps: cutting seam in the crack of broken slab, cut depth is 2-3 cm and the width of the seam is 4-5 mm, removing foul from interior of the seam, cleaning boundary to be bonded by using pressure water, drying interior of seam, injecting bonding agent and trowelling.

Description

Technical field: [0001] The invention relates to a processing method for high-grade pavement cracks. Background technique: [0002] After the existing road pavement has been used for a period of time, pavement fractures and cracks will appear. For white pavement (concrete pavement), the pressure column grouting method, joint expansion grouting method, and direct grouting method are generally used. Most of them use the whole board to clear, so that the white road surface that has just been repaired is cleared out without being used. Black pavement (asphalt pavement) generally adopts ordinary asphalt pouring method and American pouring mechanical method. After year after year, asphalt is continuously poured into the cracks of black pavement. This method of pouring asphalt has failed to seal the cracks. The effect of not entering dust, mud, sand, rain, snow and other sundries. Moreover, asphalt is also prone to cracking in cold regions. Treating road surface cracks with the ...
