Technology Puzzle
Changshu Expressway Dalings to Shuangliao Section is located in the west plains of Jilin, high vertical line indicators, can be used for vehicle driving speed, easy to cause The driver's attention is scattered, and the alertability is lowered, and it is more likely to cause a large speed difference between the small passenger car and the truck, especially the speed of the (out) flow zone into (out) the vehicle is low, and the main line is driving high-speed. The vehicle forms a large segment speed difference and a traffic conflict, causing a traffic accident. Considering this unfavorable factor, use interpenetrating polymer network (IPN) technology to prepare an environmentally friendly active prepolymerization resin PMMA (polymethyl methacrylate) film forming material; using surface hydrophobic treatment, high temperature sintering technology, Color non-slip aggregates with rainy night reflective function have been developed for highly tarwa, low-temperature and rapid construction of environmentally friendly anti-slip coatings. The research and promotion of this technology is to improve the safety design measures of high-index highways, eliminate hidden dangers during the project construction stage, and reduce property losses.
Strategic meaning
long (spring) deep (Spring) Expressway, it is of great significance for improving national expressway networks, promoting social and economic development alongline.
July 6, 2015, the Kangping section of Changshu Expressway was opened to traffic. At this point, Changchun to Shenzhen Expressway has been completed in the Liaoning territory. Another national highway network "breakway" in the territory of Liaoning Province was eliminated.
The completion of the project is not only important to improve the backward transportation situation in the northern part of Liaoning Province, and the development regional economy is of great significance, and will be a fast passage of the sea in the west of Jilin, the eastern Inner Mongolia.
Long Expressway Dalings to Shuangliao Section is an important part of Jilin Province Expressway Network Planning. This highway connection has been built with the great highway and the great highway of the Daguang Expressway, and basically realizes the full line of Changshui Expressway. It has become the second flight in the western region of Jilin, which is Jilin Province. The second largest passage in Beijing, which is 30 km from the Jingha Expressway.
