COMPARISON AND ANALYSIS OF AGGREGATE-SAND MIXTURES OF MYKYTIVSKY AND SOFIIVSKY DEPOSITS

Abstract. The article presents the results of testing crushed stone and sand mixtures from the Mykytivsky and Sofiivsky quarries of the Mykolaiv region. A comparative analysis of the physical and mechanical characteristics of the samples was carried out, the main differences in the composition and strength of the rocks of these quarries were determined. The research results allowed us to draw conclusions about the feasibility of using materials from each deposit in road construction. The results of the work will optimize the choice of building materials, which will contribute to increasing the efficiency of their use. This is especially important for road design, where it is necessary to take into account not only the initial properties of the material, but also their stability during operation. Along with this, the construction industry, in particular in road construction, is in dire need of high-quality materials. One of the most common road base materials is aggregate-sand mixtures. The use of high-quality materials in the base layers of the road pavement allows to increase the service life of not only the pavement layers, but also the road pavement as a whole. Mykytivsky and Sofiivsky deposits are important sources of building materials widely used in road construction and concrete production. The purpose of this study is to compare the physical and mechanical characteristics of materials from the Mykytivsky and Sofiivsky quarries to determine their optimal scope of application in aggregate-sand mixtures. The study will help optimize the use of materials from natural deposits in the construction industry and will improve the efficiency of choosing raw materials for specific engineering tasks in the design and construction of road.
