The formation and propagation of cracks in asphalt concrete pavements remain one of the critical challenges affecting the durability and safety of road infrastructure. This study presents the results of field observations conducted across various climatic regions of Kazakhstan to identify the correlation between climatic conditions and the intensity of transverse crack development. The collected data demonstrate that climatic conditions of the region influence the stress-strain behavior of asphalt concrete, promoting the emergence of temperature-induced cracking. Based on the analysis conducted, the study proposes a technological approach to pavement design that emphasizes the consideration of climatic factors in selecting asphalt concrete mixtures, particularly those incorporating polymer-modified bitumen binders. A key parameter recommended for inclusion in design calculations is the coefficient of thermal expansion and thermal conductivity, both of which significantly affect the distribution of thermal stress throughout the pavement system. The proposed approach enhances the crack resistance of road pavements by integrating thermophysical and mechanical characteristics of construction materials under unstable climate conditions. This facilitates the development of adaptive pavement structures capable of withstanding adverse thermal influences, thereby increasing the structural performance and long-term stability of the road network.
