The aim of the field research was to develop a method for laying and compacting coarse soil material and determining the maximum soil density and optimal moisture content. Based on these studies, technical specifications for the construction of thrust prisms are drawn up. Based on experimental data coarse soils were laid. During the experiment, the authors determined the granulometric composition of the soil, the density of the soil and the moisture state of the soil. The article discusses the laboratory method based on the research, the maximum soil density, optimality and moisture conditions of the soil. Laboratory sealing was carried out using a vibration installation 300mm in diameter and standard SOYUZDORNII sealing equipment. During field work the soil was compacted with various SANY rollers weighing 27 tons. Finally, the maximum density and optimal soil moisture were identified. The result of the work was compaction in layers with a density of 2.117 t/m3, 2.13 t/m3, 2.28 t/m3 with a layer thickness of 50, 70 and 80 cm, respectively. The soil was compacted in six to eight passes along one path using a 27-ton roller.
