Abstract

The invention discloses a mortar material for repairing a thin layer of a road surface and a construction process. The mortar material for repairing the thin layer of the road surface is prepared from the following raw materials: 200KG to 400KG of sulphoaluminate cement, 160KG to 200KG of GPO425 cement, 400KG to 600KG of customized special sand, 15KG to 35KG of 5010Wg rubber powder, 1KG to 3KG of a water reducing agent, 0.1 KG to 0.5 KG of 400 cellulose, 0.5 KG to 1.5 KG of a defoaming agent, 0.2 KG to 0.8 KG of short fibers, 0.1 KG to 0.5 KG of an expanding agent, 0.1 KG to 0.5 KG of a flatting agent and 5KG to 15KG of anhydrite. By means of the mixed materials and the repairing technology, the ground can be repaired to be neat and flush, pits of the road surface are avoided, the strength of the repaired part is high, and the surface does not cause collapse of the materials at the pits in the vehicle driving process.

Description

technical field [0001] The invention relates to ground thin-layer repair mortar, in particular to a mortar material and a construction process for road surface thin-layer repair, and belongs to the technical field of ground thin-layer repair mortar. Background technique [0002] Repair mortar is a cement-based dry-mixed mortar modified by high molecular polymers. It is mainly used for the repair of concrete defects, the reinforcement and reconstruction of old buildings and bridges, etc. It is the first choice when the thickness of the concrete surface is less than 50 mm. He brand H-XB repair mortar is similar to damaged old concrete, has good matching and excellent adhesion, and meets the compressive strength, flexural strength, wear resistance, flexibility and low shrinkage of the repair project. It has the characteristics of convenient construction, good workability, good hanging performance, easy to construct the facade and top surface of components, and has good appearan...
