Annotation The results of the road section inspection in the first road-climatic zone in the Irkutsk region are considered. The actual problem of eliminating the causes of uneven deformation of the roadbed at the initial stage of exploitation is solved. As a result of geodetic work, the degree of the roadbed deformation was established five years after the erection. The physic-mechanical properties of roadbeds are determined. Based on the results of the survey, significant deviations in the physical and mechanical properties of soils from design values, related to their additional moistening, were revealed. The connection of additional moistening of soils and subsequent roadbed deformation with a rise in groundwater level is established. The forecasting of roadbed deformations’ development, at established by researches of actual properties of soils, is executed. The embankment profile size deviation from the design is determined. The results of the studies illustrate the degree of embankment deformation dependence on the changing characteristics of the soil and are of interest in the design of the roadway under conditions similar to those considered
Key words Key words: roads; roadbed; roadbed deformation; structurally unstable soils; survey; engineering-geological surveys; soil properties; water-thermal regime of soils; deviations; methods
