Abstract
The zoning of the territory of Ukraine under the conditions of asphalt concrete work which are taken into account when designing and operating non-rigid road clothing, was developed more than 40 years ago. Therefore, the GIS database on this issue does not fully correspond to the actual climatic conditions of the regions of Ukraine. The basis for zoning is to take into account the maximum summer and winter temperatures, the number of transitions through 0°C, as well as the annual amount of precipitation. The data of field observations of climato-logical characteristics at hydrometeorological and other stations characterize the distribution of the fields of some phenomena such as temperature, pre-cipitation, velocity and wind direction, and others. These data are usually transmitted to GIS in the form of point objects (with coordinates of the observation point), which are given as attributes measured val-ues. In terms of formation of an attribute data base or GIS metadata - "Automobile Road", the tempera-ture regime is the part of geographic data, since it is tied to certain spatial (geographical) coordinates. On the other hand, the temperature regime of a par-ticular region is an integral part of the metadata base when designing road sections (CAD-RADON) or road maintenance (SUSP). Substantial changes in the temperature regime and the associated water-thermal mode of the non-rigid road clothing design led to the non-compliance of the existing zoning with the actual operating mode of non-rigid road clothing and, as a result, the discrepancy between the design values of the deformation and strength characteristics of the coating material and the basis for the actual working conditions of the structure. At the moment, there was a need for adjusting or devel-oping a new climatic zoning of Ukraine under the conditions of asphalt concrete work to adjust the GIS-AR database for calculating non-rigid road clothing according to the criteria of strength, esti-mation and forecasting of the state of highways. The analysis of the temperature regime of twenty five regions of Ukraine was carried out. The collection, systematization, statistical processing and systematic analysis of climatological parameters in these areas were carried out. The problem of the discrep-ancy between the existing geographic and climatic data base GIS - "Automobile Road" to the conditions of the current climate of Ukraine is determined. Recommendations on the need to review the boundaries of climatic regions of Ukraine are developed. In the course of the study, the methods for processing statistical data were used
