The study analyses local and foreign experience and trends in the field of improving the design of rigid structures of road pavements with the aim of a significant increase in their reliability and durability. It is shown that while ensuring the necessary quality of construction and timely completion of the full list of works on the current maintenance and repair of the construction of rigid pavements, they can serve without major repairs for 50 years or more. Based on the analysis, it was

One of the factors hindering the practical implementation of new solutions is the lag in the development of the theory of calculation and the difficulty in determining the parameters necessary for calculation that characterize the properties of materials, taking into account their heterogeneity and variability during the designed service life. A catalog of rigid pavement designs is proposed based on the predicted number of standard axial impacts for the design life of the structure before overhaul.
