Advantages of colored asphalt pavement
2021-09-26
With the rapid development of economy in various regions, the requirements of urban construction have been continuously improved. The pavement should not only meet the requirements of driving stability, but also beautify the environment, give people a good psychological feeling, and reduce the traffic problems in dangerous areas. As a new type of pavement material, colored asphalt mixture has gradually attracted people's interest and attention.
The research and application of colored asphalt mixture can be traced back to European and American countries in the 1950s, and it was quickly applied. The research of color mixture in China started late, but its development speed is fast. Hao Peiwen of Chang'an University, Lv Weiming of Tongji University and Gao Ming of Liaoning University of Petroleum and Chemical Technology have studied and applied different types of color asphalt mixture technology, and paved the test road, and achieved good results. Our company adopts AC-13C mixture grading to conduct experimental research on color asphalt mixture, including Marshall test, water stability and high temperature stability. Light color cement is used in colored asphalt pavement.
The color asphalt pavement gives people a very good visual sense. It can improve the freshness of pedestrians, thus strengthening the awareness of pedestrians. What are the advantages of the color asphalt pavement?
1. First of all, compared with ordinary cement roads, colored asphalt pavement has excellent anti-skid performance, which can protect both pedestrians and vehicles;
2. Secondly, the noise prevention effect of the colored asphalt pavement is very good. Compared with the ordinary highway, the colored asphalt pavement can effectively reduce the noise of vehicles, which is undoubtedly beneficial to the residents on both sides of the highway;
3. The construction period of colored asphalt pavement is short and the construction operation is simple; The material of color asphalt is color binder. Generally, the black asphaltene in petroleum asphalt is removed by solvent, leaving a lighter color component, and then these color materials are modified to change into red, yellow, blue, green and other colors, and then put into the pavement construction process. In addition, colored asphalt is not easy to fade and has a long service life. It is not easy to deform due to the change of weather and is easy to maintain in the later period. These are the advantages of colored asphalt. Guiyang flooring construction manufacturer is specialized in all kinds of flooring construction.
In a word, the new technology of color asphalt concrete pavement is applied more and more widely, and its application at home and abroad is too numerous to enumerate. It has the effect of creating a stable environment, giving people a good feeling, reducing traffic problems in dangerous areas, and improving the visibility of the road. Especially in traffic management, colored asphalt concrete pavement can clearly warn the driver of the road conditions ahead through different pavement colors; It can also be used to indicate different lanes and guide the traffic flow better than drawing lines on ordinary roads. Therefore, it has been successfully laid in more than 20 cities, such as Xiamen, Guangzhou, Ningbo, Guilin, Yantai, Beijing, etc., with good results and well received by the world. Development of color asphalt concrete pavement technology: Looking at the research and development of color asphalt concrete pavement application technology in the world, we can see that at home and abroad, color asphalt concrete pavement has reached a fairly mature level, but it is the same as anything. Development is endless.
