Problems solved by technology

[0003] Colored asphalt is generally used to lay municipal roads and community roads. However, with the long-term use of colored asphalt pavement, the pavement will fade and crack due to natural factors such as ultraviolet rays and rain. In addition, it may be artificially caused. stains
For the repair of cracks, using ordinary asphalt for crack potting will cause dazzling pollution, and using ordinary colored asphalt for crack potting will cause tire sticking. Therefore, there is an urgent need for a low-cost, long-life, non-stick A hot-melt color pavement crack potting material and its preparation process that can maintain the same color and adhesive properties as the colored pavement

Abstract

The invention discloses a hot-melt colorized road surface crack potting material and a preparation process thereof. The hot-melt colorized road surface crack potting material is prepared by mixing, stirring and shearing 35-40 parts of furfural extract oil, 3-4 parts of phenylethylene-butadiene-phenylethylene segmented copolymer, 27-30 parts of petroleum resin, 3 parts of dioctyl phthalate, 20-25 parts of calcium carbonate, 0.5-1 part of methylsilicone oil and 0.2-0.4 part of inorganic pigment iron oxide by weight. Compared with the prior art, the hot-melt colorized road surface crack potting material and the preparation process thereof have the advantages that the hot-melt colorized road surface crack potting material is low in cost, long in service life and non-sticking to a tyre; the hot-melt colorized road surface crack potting material has the same color as the colorized road and the same property as a sticking material; and the technical indexes meet requirements of Technical Specifications 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 hot-melt colored pavement crack potting which can maintain the same color and adhesive properties as the colored pavement and is used in the process of road engineering treatment of color pavement with discoloration and cracks. Materials and their preparation processes. Background technique [0002] With the development of my country's economic construction, colored asphalt has entered the stage of experimentation and promotion in my country. Many cities have tried to use colored asphalt concrete to lay urban roads, such as Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. [0003] Colored asphalt is generally used to lay municipal roads and community roads. However, with the long-term use of colored asphalt pavement, the pavement will fade and crack due to natural factors such as ultraviolet rays and rain. In addition, it may be artificially cause...
