Abstract

The invention relates to the technical field of pavement repair material, and provides a rapid construction highway repair material and a preparation method and application method thereof. The rapid construction highway repair material is obtained according to the following steps: adding a required amount of dibutyl phthalate, acetone, a filling material and ethene diamine in order into heated to epoxy resin, and mixing evenly to obtain the rapid construction highway repair material. The rapid construction highway repair material provided by the invention not only has the compressive strength and flexural strength of an ordinary cement concrete, but also has the advantages of short forming time and low spreading temperature, so as to reduce the construction temperature requirement and simplify the construction process. Therefore, the rapid construction highway repair material provided by the invention has higher practicability, allows usage of the highway as soon as possible, realizes full performance of usage efficiency of the highway, and shows wide application prospect.

Description

technical field [0001] The invention relates to the technical field of road surface repair materials, and relates to a rapid construction road repair material and its preparation method and use method. Background technique [0002] Highway construction is the country's basic industry and the leading industry of economic development. During the long-term use of highways, due to temperature changes, shrinkage and creep of pavement materials, loads and freeze-thaw factors, traffic lanes (highways) often varying degrees of damage. The degree of damage to the expressway is even more serious. Therefore, how to quickly and timely carry out maintenance under the condition of ensuring vehicle traffic, how to open the passage as soon as possible, give full play to the use efficiency of the expressway, extend the service life, and improve the quality of road maintenance and repair It will be a new challenge in the process of expressway development. At present, pavement repair materia...
