This article describes the territories of the northern regions of the Russian Federation, the problems of the distribution of permafrost soils (MMG), and discusses the difficulties encountered in the construction of roads in difficult geocryological conditions. The introduction of heat-insulating layers of foam glass rubble into the design of pavement is proposed. The basic physical and technical characteristics have been analyzed, and the key properties of foam glass rubble are determined. The article describes the process of production of foam glass, the advantages that allow the use of this material in various fields of construction. Typical road structures made of soil are considered. A comparison is made of a typical construction of pavement made traditionally from soil (high embankment) with a construction with a heat-insulating layer of foam-glass rubble. The advantages have been listed when using structures using foam glass rubble in road construction.
