“…Some European countries also developed climatic zones by the Superpave method from this part of Central and Eastern Europe as part of their research and development (Błażejowski, & Wójcik-Wiśniewska, 2018;Leonovich, & Melnikova, 2012). The division of the country into climate zones by the PG system, to which the authors obtained access, was performed in addition to Poland, Estonia and Belarus (Table 1).…”

The paper presents the proposition of special assessment of lowtemperature requirements for bitumens in the region of Central and Eastern Europe where there is a moderate transitional area from sea to the continental type of climate. The results of the research program conducted on the road neat bitumens, Styrene-Butadiene-Styrene polymer and polymer-rubber modified bitumen, and multigrade bitumen types were presented and discussed. Based on the Superior Performing Asphalt Pavements Performance Grade procedure for low temperatures, climatic zones in Poland were developed and compared to analogous zones for other countries from the Central and Eastern Europe region as Estonia and Belarus. The results of functional Performance Grade tests and European standard test of bituminous binders were analysed. It was concluded that some of the bitumens were not meet the performance requirements in the range of low temperatures by Superior Performing Asphalt Pavements Superpave specification and the low-temperature properties of those bitumens should be improved.

“…Asphalt becomes a plastomer that deforms under high-temperature conditions, and its shape cannot be completely recovered. Hence, asphalt pavements are prone to permanent deformation under the influence of repeated loading [24], and high temperatures are one of the main causes of the permanent deformation of asphalt pavements. High temperatures also directly affect the smoothness of the pavement and reduce the performance and service life of the road.…”

The climate regionalization of asphalt pavement plays an active role in ensuring the good performance and service life of asphalt pavement. In order to better adapt to the climate characteristics of a region, this study developed a multi-index method of climate regionalization of asphalt pavement. First, meteorological data from the research region were statistically analyzed and the major climate variables were identified. Then, a principal component analysis (PCA) was used to eliminate any correlation between the major climate variables. Three principal components were extracted by the PCA as cluster factors, namely, the temperature factor, precipitation factor, and radiation factor. The research region was divided into the following four asphalt pavement climate zones via the K-means clustering algorithm. Those zones are affected by the climate comprehensively: an inland zone with high temperatures, little rainfall, and radiation, a coastal zone with high temperatures, and a rainy mountainous zone. The results of the climate regionalization were compared with the results of on-site investigations. The pavement degradation in each climatic zone was related to the climate characteristics of the region. Probabilistic neural network (PNN) and support vector machine (SVM) climate regionalization predictive models were established with MATLAB. The clustering factors were used as the input data to identify the climate zones, and the identification accuracy rate was determined to be over 90%. The climate regionalization of pavement can provide reference and guidance for the selection of reasonable technical measures, parameters, and building materials in highway projects with similar climatic conditions.

“…At the same time, the problem of improving their shear and crack resistance remains relevant. Climatic conditions in Belarus are unfavorable for effective maintenance due to wet winter and frequent temperature transitions through zero [1]. Overabundance of precipitation leads to the destruction of the pavement material and, if it Р е п о з и т о р и й Б Н Т У contains corrosive materials, it leads to corrosion of metal bridges and other structures.…”

Climatic factors and car wheels are the reasons of changes in road condition: deformations of subgrade, cracks, potholes and rut appear, roughness and safety are deteriorating, and the strength of the road structure reduces. In our opinion, cracks in the road structure are of particular importance. The appearance of cracks causes the destruction of the whole road structure during the road operational cycle. There are many classifications of cracks depending on the reasons of their occurrence as well as repair methods of cracked asphalt pavements. The main reasons that contribute pavement cracking are: 1) horizontal tensile stresses caused by an unfree deformed pavement layers on a continuous and cracked subgrade owing to temperature changes, moving vehicles and the contraction due to the aging of asphalt mixtures; 2) transverse shear stresses in the vertical plane above the crack or joint in the base layer during the vehicles passing. We have carried out the research of the physical and mechanical properties and thermal properties of asphalt concretes, the research of the deflected mode of the pavement layers from different materials under the temperature and traffic loads using the finite element method. The results of the research on the experimental road in Pagiriai are of particular interest. These researches are original and they were carried out jointly with specialists of the Vilnius Gediminas Technical University. During the research the relation between the loading modes of the roads and an appearance of pavement damages was established, the most stable to the formation of damages road structures were revealed corresponding to climatic conditions and traffic load conditions. The mechanisms of cracking under current conditions were revealed according to the research results; the recommendations for the upper layer material choice and the choice of activities to repair the damages were formulated. These developments will improve the performance of the road and allow to do crack repair activities more effectively.
