This paper presents the results of laboratory and field compaction of coarse-grained soil. A vibratingplant with a diameter of 300 mm was used for laboratory compaction and the field compaction was carried out with a 27 tons smooth roller of the SANY type. Laboratory experiments were carried out with pattern mixtures using a standard soil compaction device SOYUZDORNII. A dependence chart of the dry soil density on moisture content is plotted and the maximum of the obtained dependence is identified, the corresponding values of the maximum density and optimal moisture content are found to determine the maximum density and optimal moisture content in the laboratory. In field conditions and with soil compaction by a 27-ton roller in four six to passes, the density is ρ=2.19 t/m3with 50 cm layer thickness, the density is ρ=2.10 t/m3 at a thickness of 70 cm and the density is ρ=2.04 t/m3with a layer thickness of 80 cm.In addition, the paper demonstrates effectiveness of the applied method of drilling and blasting in a quarry to obtain stone material of the required grain composition. Scientific work was carried out as a result of experimental studies.
