This paper presents the outcome of experimental laboratory testing of geotechnical parameters of soils specimen with various lime content and their comparison (e. g. California Bearing Ratio, compaction characteristics). Stabilization of soils using admixtures and soil improvement by lime in geotechnical design is discussed. In order to illustrate clay improvements, three of the most frequently types of clays in Slovakia were used for experimental study and the content of lime varied from 0 to 4 %. Results of the laboratory investigation with the soil treated and the changes of mechanical properties due to lime addition as far as the results from the field lime treatment are analyzed in the paper. Some case studies on ground improvement by lime from Slovakia are presented. The correlations, tables and graphs based on the empirical relationship between the value of California Bearing Ratio and modulus of elasticity which are used in geotechnical practice are discussed in the paper. Significant differences were observed in determination of the derived values of elasticity modulus using empirical correlations and the values determined by laboratory testing.
