Problems solved by technology

[0002] As we all know, urban roads have a large traffic flow and many pedestrians. When the road surface cracks, it needs to be repaired immediately, otherwise it will affect driving safety. At the same time, if it is not repaired in time, the cracking of the road will be accelerated and its life will be affected.

Abstract

A GTP-1 type composite cementitious material for rapid repairing of asphalt concrete cracks comprises an interfacial adhesive and a cementing material. The interfacial adhesive comprises a component A and a component B in the ratio of 10: 8; the cementing material comprises a component A, a component B and a component C in the ratio of 100: 42: 5.6. The component A consists of 20-40 parts of waterborne epoxy, 0.2-0.8 part of polyurethane and 45-75 parts of water; the component B consists of one or two of 4-16 parts of magnesium sulfate and calcium sulfate; and the component C is composed of 1-3 parts of a modifier and 5-10 parts of calcium stearate. The product is a reaction system, and the reaction time changes according to the temperature. The invention has the advantages of low cost, simple construction process, good treatment effect, no environmental pollution, and wide market application prospects.

Description

technical field [0001] The invention relates to the preparation of a special epoxy material for rapid urban road cracking, which is used for rapid repair of urban road cracking. Background technique [0002] As we all know, urban roads have a lot of traffic and pedestrians. When the road surface cracks, it needs to be repaired immediately, otherwise it will affect driving safety. At the same time, if it is not repaired in time, it will accelerate the cracking of the road and affect its life. Due to the special geographical environment of urban roads, when repairing cracked road surfaces, the construction process is required to be fast and simple, the treatment effect is good, and there is no environmental pollution. The invention has the characteristics of simple processing, low cost, convenient use and excellent performance, and is very suitable for quick repair of urban road cracks. Contents of the invention [0003] The object of the present invention is to solve road ...
