Ключевое слово: «frozen soils»

The construction of roads in the soil with permafrost showed that the general technical developments obtained in the last century do not allow taking into account existing problems in geocryological conditions. Currently, the construction of highways is carried out in various geographical conditions. In this case, depending on climatic conditions and geological features of the area, roads with various technical parameters are erected. For example, for areas of permafrost soils, various technologies that are implemented in the construction of highways. For areas of permafrost soils, as a rule, the general method would be laying the roadbed with its subsequent thermal insulation. The article discusses the features of thermal insulation in permafrost areas, where the aspects of construction of the roadbed were revealed as well as considered methods of laying geo-synthetic materials.
