The application of a mechanical-empirical method of designing road pavement for predicting track formation on the surface of road structures is discussed in the article . The occurrence of ruts is one of the most common types of defects in road surfaces, significantly reducing safety and comfort of movement. MEPDG calculation models were used in this work for assessing the stability of a road structure to the accumulation of plastic deformations. Models takes into account factors such as the intensity and axial load of transport, climatic conditions, and the physic and mechanical properties of coating materials. An example of predicting the depth of a track using the considered method is given.
