Introduction. This article examines the issue of improving the methods of designing and calculating rigid road surfaces, outlined in the DSTU project “Guidelines for the Design of Rigid Road Surfaces” (hereinafter referred to as the DSTU project). The specified methods were developed on the basis of domestic and global experience in the design of highways with rigid road surfaces, analysis of current legal acts, regulatory documents, technical literature related to the object of standardization, taking into account the availability of modern road construction materials and technologies. density of traffic flow, diversity of subsoil, including in complex engineering and geological conditions, peculiarities of road and climatic regions of Ukraine, etc.
Problem statement. The need for improvement and a unified approach to the design of rigid road clothing, taking into account the peculiarities of its operation, with the determination of the appropriate parameters depending on the initial data and the effective use of material and technical resources.
Materials and methods. The article uses the work of SE “NIDI” and the National Transport University based on the experience of providing services, current building regulations and national standards, information materials of foreign normative documents and technical literature on the design of rigid road surfaces, domestic and international experience gained during the execution of construction works . During the development of DSTU, the results of laboratory studies on determining the calculated characteristics of road cement concrete, including those reinforced with steel or composite reinforcement, were also taken into account.
Results. In order to implement modern methods of designing highways with rigid road surfaces, the DSTU project and Handbook No. 1 “Calculation characteristics of soils, road surface materials and vehicle loads” were developed, the requirements of which apply to the design and calculation of rigid road surfaces with a cement concrete road surface with a pin with by connecting plates, with reinforcement and pin connection of plates, with continuous reinforcement and using rolled cement-concrete mixtures.
Conclusions. The proposed method of designing rigid road surfaces on highways improves the existing ones and establishes new, scientifically based, modern requirements for design and calculation parameters, which will contribute to increasing their strength, reliability and durability.
