The problems of assigning design characteristics of soils of the working layer of the subgrade of transportation structures and their compliance with actual data are considered. The research of deformation parameters of soils in the laboratory by two methods, on two devices is carried out: Litvinov's field laboratory «LFL-9» - a device for compression tests and an odometer in the automated system of engineering tests in construction «ASETC». The results of laboratory studies are compared with the data of normative documents. The actual problems, the solution of which is aimed at increasing the reliability of assignment of design parameters of soils for backfilling of the working layer of the earth bed, have been determined. The possibilities of the program “GEO5 Sedimentation” allow to model the earth bed and to select the necessary deformation modulus and to perform the calculation according to the compression curve.
