TERRITORIAL NORMALIZATION OF STRENGTH AND DEFORMATION PARAMETERS OF CLAYEY SOILS

The present article describes approach towards the database formation for justification of the calculated values of subgrade clay soils properties considering roads of West Siberian region. Aspects of the methodology have been considered aimed at providing quality design of roads by means of accounting natural-climatic conditions of separate administrative units of Russian Federation. The stages reflecting validation of calculated values of strength and deformation properties of clay soils are shown. The dependences of change in elasticity modulus, the angle of internal friction and specific cohesion of clay soil on relative humidity were established. The calculated values of moisture, elasticity modulus, angle of internal friction and the specific adhesion of clay soils subgrade are given.
