Problems solved by technology

However, asphalt is added to the caulking materials of the existing highway asphalt pavement, so that the caulking materials become black, and even if colored pigments are added, they are also in a black state. After modifying the cracks of the colored pavement, the aesthetic effect will be seriously affected, and now Some asphalt caulking materials are difficult to mix with color pigments, or after mixing with color pigments, the repair effect will be affected, the overall performance of the caulking materials will decrease, and the service life will be affected
[0007] To sum up, cracks and other diseases will inevitably appear on the colored asphalt pavement affected by the external environment, and the repair of cracks requires special caulking materials. The patching has been blank, which to a certain extent inhibits the promotion of colored pavement

Abstract

The invention discloses a caulking material for color asphalt pavements, and a preparation method thereof, wherein the caulking material comprises, by mass, 5-20% of a petroleum resin, 55-76% of a compatibilizer, 8-25% of a polymer, 0.05-4.0% of a vulcanizing agent, 0.1-4.0% of a coupling agent, 0.05-2.0% of a reducing agent, and 0.2-3.0% of an anti-aging agent. According to the present invention,the caulking material has advantages of excellent high temperature performance, excellent low temperature performance, excellent deformation recovery capability, high softening point, strong bondingforce, high low-temperature elongation rate and high low-temperature ductility, and can be well mixed with color pigments, wherein the obtained mixture can effectively repair the color asphalt pavement with cracks.

Description

technical field [0001] The invention relates to a caulking material and a preparation method thereof, in particular to a caulking material for colored asphalt pavement and a preparation method thereof. Background technique [0002] Colored asphalt pavement improves the black monotony of ordinary asphalt pavement, can match and coordinate with surrounding buildings and landscapes, and has obvious landscape effects. 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 to pave urban roads, such as Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. In addition, the role of colored asphalt in traffic organization and management has been paid more and more attention. Different colors of asphalt pavement can improve the recognition effect of the driver, and can also make the driver's attention more concentrated, thereby playing the role of inducing t...
