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.
Objective. To find and develop optimal technological solutions for the construction of a durable pavement, which will be less sensitive to the inherent characteristics of our country, prolonged high temperatures in summer and highly cyclic temperature changes in winter, as well as have significant strength to ensure the ability to withstand the high intensity of heavy vehicles.
Materials and methods. The presented work is based on analytical, practical and theoretical studies related to the requirements of standardization for the construction of roads with cement concrete pavement.
Results. In order to introduce modern technologies for the construction of roads with rigid pavement, a set of national standards has been developed, the requirements of which apply to the construction of cement concrete pavement with pin connection of plates, with continuous reinforcement and using rolled cement concrete mixtures. Regulatory documents provide for the use of cement-concrete pavement mixtures and the use of various types of specialized equipment during the construction of roads.
Conclusions. The requirements given in the developed regulatory documents regarding the arrangement of cement concrete pavements are averaged solutions. As a result of the conducted research, study of domestic and world experience and analysis of various technical documentation, technical solutions for the construction of cement concrete pavements with pin connection of plates, with continuous reinforcement and using rolled cement concrete mixtures have been developed. These technologies are alternative to asphalt concrete pavement construction and have a large number of advantages that are of particular importance for Ukraine at the present time. Based on the results of the work performed, the most optimal, at the moment, basic requirements have been established that regulate the principles of building high-quality, durable roads with comfortable traffic, taking into account modern European standards.
