This paper presents research results of subgrade deformations leading to the loss of road stability on the Osh-Isfana road section in the South of Kyrgyzstan. The soil humidity of the sloping subgrade area occurs due to precipitation, so the paper considers the relationship between the subgrade settlement and atmospheric precipitation in the road-climatic zone V. The influence of the soil humidity on its physical and mechanical properties are determined as well as the critical values of humidity for each investigated area, when deformation can occur. The geological structure and parameters of physical and mechanical properties of soils are determined in the road section at issue. Subgrade settlement is evaluated and predicted in this work. The results can be used in road design and reconstruction with regard to the geological conditions of the Kyrgyz Republic.
