This paper presents the results of determining the optimal moisture content and the maximum density of the plasticity number of loamy soil, the results of studies and experiments to determine the most promising ways to reduce quarry soil moisture. In addition, the results of studies on the development of a quarry, determination of the thickness of an uncompacted layer, the choice of a compaction mechanism, the number of passes along one track, the determination of the density of dry soil in the proposed experimental field areas during the backfilling of the dam, and graphs of the required densities are presented.
