In the current socio-economic reality, the main task of design, road organizations is the high-quality reproduction of road structures, the development of the road network, and also to maintain the transport-operational condition of the highway. In this paper, examples and models are provided that allow an estimation of the probability of destruction of individual sections of a road structure, as well as the dependence of the reliability of a road structure on the actual coefficient.
