Taxon Boundaries Unifying Homogeneous Territories by Geocomplex Features in Climatic Zonation

Road-building climatic zonation developed in the 1950s for the territory of the former Soviet Union, does not take into account natural climatic conditions of many regions occupying a significant area of Russia, which limits periods between the highway repair. The development of new territories, for example, the vast Arctic zone, requires a methodological approach from various organizations to the areas by the geographical complex, within which the same type of road structures will be characterized by the same strength and stability. To date, there is no unified, standardized methodology of road-building climatic zonation, providing the required level of reliability of structural and technological solutions at design and construction stages of roads.Purpose: To summarize the results of long-term studies carried out by the authors on the territory of 14 administrative formations of the West Siberian region.Research findings: Schematic is proposed for taxonomic division of territories based on the elements of the geographical complex of administrative entities of the Russian Federation. Differences between the calculated values of clay soil properties given in normative documents and experimental data, are shown on the example of the territory of the Omsk region.
