- Abstract
main tasks of research and maintenance of reliability at the present stage of designing and construction of highways are stated. The sequence of the analysis of structural reliability schemes of non-rigid road clothes under conditions of impact on them of normal and limiting values of transport - operational loads and weather climatic conditions – is considered. During the analysis of structural reliability schemes, the quantitative characteristics of the reliability of layers of the road structure are determined on the basis of the representation of the physical model of their failure, which includes a complete group of events (failures) of the layers of the road structure and the road structure in general. In this case, the model of failure of each layer is represented by a small number of determining factors (“limiting” parameters, such as the modulus of elasticity, the smoothness of the road surface, rutting, cracking, etc.) allowing their quantitative measurement or calculation according to the corresponding deterministic relationships. These correlations are usually found from the theory of designing the corresponding typical road projects or from the results of specially set experiments.
