Abstract	The paper presents an example of designing the consolidation improvement of the organic subsoil under expressway by staged construction with preloading using vertical drains and geotextile. In the subsoil of road embankment there are organic soils (peat, gyttja) with a thickness of 4.5 m. The geotechnical parameters determined on the basis of in situ tests and laboratory tests were used in the stability analysis and the consolidation prediction. The calculations were carried out using the GeoSlope and Plaxis numerical programs, determining the safe heights of the individual stages of the embankment construction and the time needed to consolidate the organic subsoil. The results of the numerical analysis indicated zones of settlement nonuniformity that require additional strengthening of the embankment. The significant variation of the organic soil properties and the different location of the designed embankment in relation to the existing one indicates the necessity of control measurements of vertical and horizontal displacements as well as pore water pressures in organic subsoil.
