Abstract

 
 
 The article considers the problems of road-climatic zoning of the territory of Ukraine. The shortcomings of the existing system and the need to update and improve it were justified. The purpose of work was formed and realized taking into account modern approaches to meteorological data processing and segmentation methods. The study is based on long-term observations of weather conditions throughout the country. Using the moisture-thermal regime calculation and analytical system, the collected static meteorological information was processed and tables of the initial data for further analytical processing were obtained. The paper describes the methodology of cluster analysis using as the main tool for the typification of territories and the allocation of morphologically homogeneous humid areas. The result of the work was the elaboration of a road and climatic zoning map under the wetting conditions of the road subgrade working layer.
 
 
Highlights
The need to improve road-climatic zoning and to develop recommendations on the application of climatic characteristics and climatic zoning of the territory of Ukraine for road construction is due to the fact that these issues were developed back in 70-80 years of the last century using data on climatic conditions throughout the territory of the former USSR
The elements of the road structure are subject to increased precipitation effects, which leads to a change of the whole structure waterthermal regime (WTR)
Road-climatic zoning takes into account the natural and climatic characteristic, and the features of road construction and maintenance
Summary
The need to improve road-climatic zoning and to develop recommendations on the application of climatic characteristics and climatic zoning of the territory of Ukraine for road construction is due to the fact that these issues were developed back in 70-80 years of the last century using data on climatic conditions throughout the territory of the former USSR. The elements of the road structure are subject to increased precipitation effects, which leads to a change of the whole structure waterthermal regime (WTR). Moistening of the road structure is the main cause of destruction and deformation. Approaches to the design of WTR regulation structures should vary according to the external influences intensity. Drainage systems designing requires to updating, methodological regulation, taking into account the modern meteorological information, and obtaining special meteorological values databases that are estimated value in road construction elements designing procedure
