TO MODIFICATION OF ROAD CLIMATIC ZONING OF KAZAKHSTAN

Paper shows short information regarding meteorological stations for weather observation in Kazakhstan. Data are represented regarding maximum and minimum values of air temperature for the period from 2006 to 2011, obtained by data processing of 40 meteorological stations of Kazakhstan. The results are represented in the form of climatic map of the Republic for minimum air temperature values for the specific period of time. Adjusted map is represented regarding soil frosting depth throughout Kazakhstan, constructed on the basis of frosting depth data, determined by calculation according to empiric formula, developed in JSC KazdorNII. Information is shown regarding automatic sets for temperature and moisture measurement in points of pavement and subgrade of highways, installed by JSC KazdorNII in five regions of Kazakhstan. Aiming at the performance of long-term monitoring for temperature and moisture variation in points of pavement and subgrade of highways 3 special measurement sets, equipped with sensors of temperature and moisture (on road sections of the highways with asphalt concrete and cement concrete pavements) in different climatic conditions were installed close to Astana city in 2010. Then similar sets were installed close to Oskemen, Almaty, Shymkent, Atyrau cities in 2013. Information is contained regarding construction of climatic maps by other specialists. Empiric ratios have been used, which are based on meteorological data regarding air temperature variation, during mapping on frosting depths of subgrade of the highways. It is noted that together with the increase of stations number for experimental research of temperature and moisture variations in road structure in time, it is required to develop widely the works on investigation of processes for non-stationary temperature field variation and moisture regime in road structure by mathematical modeling methods.
