INNOVATIONS IN THE UKRAINIAN REGULATIVE FRAMEWORK FOR THE CONSTRUCTION OF HIGHWAYS WITH CEMENT-CONCRETE COVERING

Abstract

Introduction. The article deals with the issues of expanding the regulatory and technical base of the road sector for the construction of roads with cement concrete pavement. The article covers the issues of improving the existing and developing new requirements for the construction of cement concrete pavements with pin-connected slabs, reinforced slabs with pin connection, with continuous reinforcement and using rolled cement concrete mixtures using modern technologies. Improvement of the national regulatory framework is carried out on the basis of the analysis of existing legal acts, regulatory documents, technical literature related to the objects of standardization and, of course, taking into account the requirements of safety and environmental protection and the factors and features established by the current martial law in Ukraine. The work concerns the developed national standards for the installation of cement concrete pavements, namely those innovations that have already been agreed upon and are planned to be submitted to the National Standardization Body for adoption in the near future. Problem statement. Implementation of a unified technical policy to ensure the reliability and durability of roads, increase the efficiency of capital investments, implementation of scientific and technical achievements of science and best domestic and international practices in the practice of construction of roads with cement concrete pavement, issues of saving material, labor, financial and energy resources, improving the quality of construction work, labor safety and health conditions, rational use of land and other types of natural resources. The fact of constant growth in the intensity of heavy vehicles traffic, which is associated with the transportation of heavy machinery, agricultural products, metallurgical products, etc., significantly affects the reduction of the service life of roads with non-rigid pavement. This necessitates the search for alternative solutions for the construction of more durable pavement structures, one of which is the improvement of existing and introduction of new technologies for the construction of cement concrete pavements.
