Abstract
This article studies the compaction of clay soils. Clay soils are often used as building foundations. However, such a use is complicated by their specific properties, namely the dependence of structural properties, particularly deformation patterns and strength, on the compaction degree. Compaction is one of the most important properties of clay soil, largely determining its behavior under load. Compaction can be used as a classification indicator, as well as for preliminary assessment and prediction of the soil behavior under various stress-strain conditions. As is known, the compaction of clay soils is influenced by various factors: occurrence depth, sediment and clay composition, environment and compaction conditions.
Purpose: The aim of this work is to refine the compaction classification of clay soils with the possibility of using for practical purposes.
Methodology: The article analyzes the dependence of average density of dry soils on the natural moisture content in genetic soil types.
Research findings: The current classification of clay soils is refined, depending on the dry soil density. The obtained dry soil density dependence ρd = f (We) determines the boundaries of We, ρd for certain genetic soil types.
