Abstract. In this article, the authors briefly reviewed the problem of building roads on permafrost soils, according to the first engineering principle. The probable causes, affecting the thermal regime of the frozen soil at the base of the road, are also considered. In order to stabilize the road structure on permafrost soils, the team of authors of this article proposed 3 structural-technological solutions for the construction of roads, depending on the moisture levels of the upper soil mass, calculated for geotechnical and temperature-humidity conditions typical for the Yamalo-Nenets Autonomous district. The scheme, description and assessment of the effectiveness of each proposed structural-technological solution is given. Efficiency of the assessment is based on a comparison of the numerical modeling results of the water-thermal mode of mound with the proposed structural-technological solutions and ground embankments of roads on permafrost. The results of the numerical modeling of road embankments on permafrost soils are presented. The main conclusions of the research are formulated.

Keywords: road; permafrost soils; structural-technological solution; numerical simulation; water-thermal mode; embankment; granulated heat insulation material
