RESEARCH OF THE TECHNOLOGICAL FEATURES OF THE PAVING TILES MANUFACTURE FOR THE IMPROVEMENT OF INDUSTRIAL AND CIVIL FACILITIES

Abstract

Purpose. The purpose of the scientific article is to substantiate the parameters of the production of high-quality paving slabs and to determine the basic principles of paving technology of road surfaces using paving slabs. The work is based on the experience gained in the field of paving stone production, specifies the basic principles of its production, as well as methods that allow to increase its strength and resistance to the effects of weather conditions, mechanical influences and loads. Methodology. The research was carried out in accordance with the current regulatory documents that regulate the research of construction composites, raw materials for their manufacture and finished products, which were considered in the submitted work. A number of experimental studies of fine-grained concrete have been conducted from the point of view of their physical and mechanical properties and the parameters of the construction of road surfaces from manufactured elements. Findings. When installing paving slabs, it is necessary to take into account not only the quality of the products themselves, but also observe the technology of laying the soil base for paving. It was established that not only the main composition of fine-grained concrete is important. It is determined from which raw materials and under which manufacturing conditions it is possible to obtain high-quality, durable products. An analysis of the compositions that are most widely used in the conditions of modern production of paving stones is given. The most rational dosage of each component, which affects the properties of the working mixture and the finished construction coating, is also given. Originality. The relationship between the combination of components of fine-grained concrete, which allows obtaining high-quality small-sized products for the installation of a road surface, has been established. The list of the most common paving defects that occur during the manufacturing process has been defined and the technological requirements for the preparation of the soil base for the road surface have been established. Practical value. The obtained research results allow to product high-quality paving slabs, which have the necessary indicators for the installation of a durable road surface. The conditions for the preparation of the ground base for the paving of road surfaces are determined and the importance of their observance is substantiated. This will increase the efficiency of work and ensure the comfort of the population.
