    Abstract. Long-term studies have established that the characteristics of compressibility of soils obtained under the laboratory conditions are very different from performed in the field. It is proposed to use inexpensive laboratory tests to determine the compressibility characteristics of soils instead of expensive field tests. To be able to use the deformation modulus obtained in the laboratory, a comprehensive study of both natural and laboratory sandy soils was carried out. Comparing the results of numerous experiments, it was possible to determine the conversion factors for adjusting the deformation modulus of sandy soils, which, in particular, were obtained in full-scale tests with stamps of different areas, static sounding, as well as in the laboratory during compression tests. The results of tests of foundation sandy soils conducted at three construction sites are considered. The studied sands had various composition (from loose to dense) and particle size distribution (from fine sands with the inclusion of dusty and clay particles to large sands). Conversion coefficients for the deformation modulus of sandy soils of various granulometric compositions obtained in laboratory and field conditions are given.
    Key words: sandy base soils, conversion factors, experimental studies of base soils, deformation modulus of soils.
