This paper is intended to study the mechanism of strains and fractures emerging in pavement structures, give suggestions and recommendations to increase the robustness of different types of road pavements with the most appropriate design solutions. The subject of the research is the evaluation of strain mechanisms in cement and composite pavements caused by weather conditions. The scope of the research is to analyze the impact of ambient temperature variations and water and thermal state of the subgrade on different types of road structures. These are the most critical factors which give rise to adverse environmental effects causing dangerous stresses and strains in the pavements. The research results are represented as follows: analysis of the regularities of strains of different types of pavements exposed to weather conditions, modern methods of reduction of temperature and humidity factors on different types of road structures, providing recommendations to improve the robustness of different types of pavements to improve the usability of roads which will result in lower operating costs (repair and maintenance of pavements) and higher traffic safety (reduction of the number of road accidents).
