The problem of road structures deformation and demolition is still of vital importance nowadays. The reason of various demolitions, in most cases, especially during the period after winter, is oversaturation of the earth subgrade roadbed level with water and its load-bearing ability consequent losing. Due to the mentioned problem and related ones, this publication is devoted to the issues of defining calculated characteristics of the structures for regulating moisture and thermal regime of the road structure - shallow laying drainages. In the following article one can find an improved method of calculating the freezing depth of a road construction within the layers of its pavement and ground belonging to the active zone of the earth subgrade roadbed. On the basis of the statistical analysis of climatological indices for the last ten years, it is the first time within the territory of Ukraine when road-climatic maps have been developed to study the ground freezing depth under the road pavement. These maps have been built for all technical categories of roads according to the adopted regulatory documents. The renewed approach permits developing reasonably improved measures concerning regulating moisture and thermal regime of a road structure and eliminating the time-consuming process of receiving the arrays of meteorological information and their statistical processing.
