Problems solved by technology

At present, the commonly used maintenance method in China is: use the paint of the same color to repair, but if you use solvent-based paint to infuse, the cost will be high and seriously pollute the environment; if you use water-based paint to infuse, the bonding strength will be small, and it will easily resurface when it encounters water. Therefore, there is an urgent need for a water-based color pavement crack sealant and a water-based color pavement crack sealant that coagulates quickly, has high viscosity, low cost, no pollution, long service life, is easy to promote, and can maintain the same color and binder properties as the color pavement. Its preparation process

Abstract

The invention discloses a colorful road surface crack aqueous sealing material and a preparation technology of the same, wherein the aqueous sealing material is used in the processing engineering of roads with defects such as cracks, pits and the like on the colorful road surface. The aqueous sealing material is prepared by shearing material A and material B in weight ratio of 60-70%:30-40% by a colloid mill, wherein the material A is prepared by mixing the following components in parts by weight: 50-55 parts of furfural extract oil, 3-4 parts of styrene-butadiene- styrene block copolymer and 37-45 parts of petroleum resin; while the material B is prepared by mixing the following components in parts by weight: 2-3 parts of hexadecyl trimethyl ammonium bromide, 0.7 part of inorganic pigment, 1 part of methyl cellulose and 95.3-96.3 parts of water. The colorful road surface crack aqueous sealing material has the advantages of being capable of coagulating to blocks, high in viscosity, low in production cost, free of pollution, long in service life, convenient for polularization and same as the colorful road surface in color and binding material in property, and meeting the requirements of Technical Specification for Highway Asphalt Pavement Recycling (JTGF41 - 2008).

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a water-based colored pavement crack potting method used in the process of treating road engineering diseases such as cracks and pockmarks on the colored pavement, which can maintain the same color and binder properties as the colored pavement. Sealant and its preparation process. Background technique [0002] With the continuous progress of society and the continuous improvement of people's living standards, people's requirements for the living environment are also gradually increasing. As a paving material with beautifying environment, colored asphalt has entered the stage of experimentation and promotion. Many cities have tried to use colored asphalt concrete. Lay roads in cities like Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. There are many colors of colored asphalt mixture, but generally red, yellow, green and blue are the main colors. ...
