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, the use of ordinary asphalt for crack potting will cause dazzling pollution, and the use of general colored asphalt for crack potting in high-temperature environments is prone to melting, sticking tires, and sticking feet, causing pedestrians Inconvenient, therefore, there is an urgent need for a high-temperature-resistant hot-melt colored pavement crack potting material and its preparation process that is high-temperature resistant, long-lasting, and can maintain the same color and adhesive properties as the colored pavement.

Abstract

The invention discloses a high-temperature-resistant hot melting type colorful pavement crack encapsulating material and a preparation process thereof. The encapsulating material is obtained by mixing, stirring and shearing the following raw materials in parts by weight: 35-40 parts of furfural extract oil, 3-4 parts of styrene-butadiene-styrene block copolymer, 4-5 parts of ethylene-vinylacetatecopolymer, 23-25 parts of petroleum resin, 3 parts of dioctyl phthalate, 17-21 parts of calcium carbonate, 0.5-1 part of methyl silicone oil and 0.2-0.4 of pigment. Compared with the prior art, the encapsulating material prepared by the process in the invention has the advantages that cost is low, the service life is long, high temperature can be resisted and simultaneously the color and adheringproperty of the encapsulating material are maintained to be the same as those of colorful pavement, and the technical index of the encapsulating material reaches the requirement of highway bituminouspavement regeneration technical regulation (JTGF41-2008).

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a high-temperature-resistant hot-melt colored pavement crack used in the process of treating diseases such as discoloration and cracks on the colored pavement, which can maintain the same color and adhesive properties as the colored pavement Potting material and its preparation process. 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 art...
