The paper investigates the process of compaction of a sand layer with a manual vibroplate under various technological conditions. The moisture content of the sand layer was previously determined in accordance with the accepted methodology. Then, as a result of preliminary experiments, the authors selected the limits of variation of some technological parameters of the vibroplate. To reduce the volume of experiments and increase their accuracy, the authors used an almost rotatable three-level non-factorial plan. The obtained experimental data were processed using the Statistika.exe software. As a result, the obtained mathematical models describe the dependences of the density of the sand layer on the mass of the additional load and the speed of the vibroplate, as well as on the frequency of rotation of its unbalanced shaft. The results are presented in the form of three-dimensional graphs and equations describing the compaction process. The paper analyses the research results and conclusions. They will allow to determine some optimal technological parameters of the vibroplate during the compaction of the sand layer.
