Interim tests of an innovative type of road barrier, i.e. cable barriers, have been successfully completed on one of the sections of the Astana-Karaganda (KAZ01) highway of republican significance in the Karaganda region with a high risk of snow accumulation.
The tests were conducted on a 500-meter-long experimental section near the city of Temirtau. The cable equipment was installed along the road in the direction of Karaganda, specifically on the belt separating the lanes and on the right side of the road. As a result of the tests, this device showed high efficiency in adverse weather conditions (during a blizzard).
Cable barriers have significant advantages over traditional metal barriers. They are especially effective in conditions of heavy snow and strong winds. They allow snow to pass freely through the cables. This prevents it from accumulating on the dividing strips and edges of the road. Such barriers also help reduce the cost of mechanical cleaning of roads. The mentioned types of fences are actively used in the USA, Japan and Europe due to their economic efficiency.
The project is being implemented under the scientific and technical guidance of specialists from the Kazzhol Research Institute. They will conduct a two-year monitoring of the effectiveness of cable fences in various weather and operating conditions. If the experience gives positive results, cable fences can become an alternative to traditional metal barriers in areas with a high risk of snowfall. It is expected that these fences will ensure safe movement in winter.
