Terms and efficiency of prefabricated coverings used at temporary forest roads

摘要

The article describes the conditions and the effectiveness of application of prefabricated coverings at forest roads, such as concrete slabs, wooden shields, band coverings and others. Their advantages and disadvantages have been considered. Prefabricated coverings have found a wide application in the transport development of forests located on the water-logged lands. They have high technical-economic indicators. The specific resistance of the vehicle movement is 2–3 times lower than at soil roads. They also reduce the consumption of fuel and lubricating materials. They reduce financial expenses for road maintenance.
