Abstract. In the first quarter of the 21st century, Russia will face the need to develop the southern latitudinal belt and form a new northern latitudinal belt of Russia’s economic development in Siberia. At the same time, specialists from the Institute of Economics and Industrial Engineering of the Siberian Branch of the Russian Academy of Sciences predict the possibility of strengthening the single economic space of the state, relying not only on raw materials, but also on the transport and logistics opportunities that open up when servicing transport corridors. The development of the road network of the northern latitudinal belt of economic development requires taking into account the features of the geocomplex elements when designing roads in the territory of the second climatic zone of Western Siberia.

The article presents the structure of research aimed at studying the relations and patterns that determine the systemic relationship between the components of the «highway – environment» system in economically promising areas of Western Siberia. The research structure is based on the systems approach and includes two main blocks – theoretical and experimental ones, as well as their elements and internal and external relations.

The study gives the detailed examination of such issues as organization and performance of experimental part of research on studying composition and properties of clay soils.

The main outcomes of field and laboratory studies are shown. The dependences of variations of elastic modulus, angle of internal friction, and specific adhesion of clay soils on their relative humidity are established. Deviations are determined between the values of soil characteristics calculated from these dependences and the values presented in Industry Road Code 218.046-01 (preliminary national standard PNST 265-2018).

The article is prepared on the basis of the author’s PhD dissertation research on the topic of «Justification of regional calculated values of clay soil characteristics for the road pavement design in Western Siberia» (STU, Novosibirsk, 2017).

Keywords: road; subgrade; pavement; calculated values; clay soils; functional dependences; standardization of properties
