Quick repairing material of airfield pavement and road, and preparation method and construction method of quick repairing material

Abstract

The invention provides a quick repairing material of an airfield pavement and a road, and a preparation method and a construction method of the quick repairing material. The quick repairing material comprises the following ingredients in parts by weight: 30-35 parts of polymethyl methacrylate resin, 10-15 parts of calcium carbonate, 5-10 parts of bentonite, 1-5 parts of nano silicon oxide, 10-20 parts of quartz sand, 2-5 parts of inorganic pigment, 0.5-1 part of an anti-settling agent, 0.5-1 part of a thickening agent, 5-10 parts of bauxite and 5-10 parts of carborundum. The material takes thepolymethyl methacrylate resin, the bauxite, the bentonite, the thickening agent, the anti-settling agent, the quartz sand and the carborundum as main materials, has excellent performance of fast curing within 1h at -30 DEG C, ultra-high cohesion, excellent crack resistance, acid resistance, alkali resistance and chemical resistance; emission of VOCs (volatile organic compounds), heavy metals andthe like is lower; the environmental pollution is reduced; the problems of defects such as cracks, dusting and damage of a maintenance surface are avoided; and the traffic efficiency of the road is greatly improved.

Description

technical field [0001] The invention belongs to the field of airport pavement and road repair materials, and in particular relates to a rapid repair material for airport pavement and road and a preparation and construction method thereof. Background technique [0002] In the maintenance and repair of roads and airport pavements, due to the influence of factors such as vehicle driving, aircraft take-off and landing, and low-temperature construction, the construction work area cannot be closed for a long time. In order to reduce the closing time of the construction area and ensure the smooth flow of traffic, it is necessary to repair the damaged area in time and quickly. [0003] At present, concrete or fast-hardening concrete and other resin slurries are generally used for repairs. Not only the construction period is long, but the construction procedures are complicated and the traffic time is too long, and it cannot be constructed below zero. Cracks, broken plates, Sand, pi...

Problems solved by technology

[0003] At present, concrete or fast-hardening concrete and other resin slurries are generally used for repairs. Not only the construction period is long, but the construction procedures are complicated and the traffic time is too long, and it cannot be constructed below zero. Cracks, broken plates, Sand, potholes and other diseases, so the ideal repair effect cannot be achieved
