Abstract: The paper presents the results of tests on samples of cohesive soils from Lower Silesia, concerning recognition of their ability to shrinkage under the drying to 110°C. The parameters defining the shrinkage of soil were: shrinkage limit, shrinkage rate and coefficient of linear and volumetric shrinkage. Using set of more than 80 tests results, presents an attempt to determine the correlation mentioned parameters according to shrinkage with other identification parameters investigated soil. Also estimated the usefulness of formulas given in the literature to approximate soil shrinkage parameter estimation calculated on the basis of other physical characteristics of the soils. Pointed the strong influence of local conditions on the values of the soil shrinkage.
