For their research, thermomechanical and mathematical models of thermomechanical deformation of heterogeneous structures with reinforcing inclusions in the form of systems of differential equations were developed. Their solutions were constructed using computer and analytical methods. It is shown that the internal mechanism of nucleation of concentrators of intrastructural thermal stresses in the interface areas between the contacting phases of the material and the reinforcement, provoked by the incompatibility of the thermomechanical fractions of the system, can be the main reason for the initiation of thermal damage (in particular, at the microlevel, and therefore inconspicuous at the initial stages), which contribute to degradation material and its subsequent destruction. The use of developed methods for modeling intrastructural thermal damage and recommendations for reducing their levels in the design of multilayer and reinforced road and bridge coatings will make it possible to increase their strength, load capacity and durability.
