The article reviews the issue of the stress-strain state of the road surface in the winter period as a result of roadbed soil heaving. The main purpose of the work is to determine the stress fields in the asphaltconcrete pavement, which is necessary for designing of frost-resistant roadbeds in the areas with seasonal freezing of roadbed soils. The following research methods were used: theoretical, laboratory, field. With consideration of different properties of materials and geometric dimensions of the road surface section, stress fields in the asphalt-concrete pavement during freezing were obtained with the use of the software product. Comparison of theoretical studies with the results of experimental and fullscale tests showed that the forms of theoretical solutions describe the stress fields in the freezing asphalt-concrete pavement quite accurately.
