The main purpose of this work is to determine the optimal operation modes of vibratory rollers, which contribute to the effective compaction of sandy soils. The relevance of the article is due to the need to apply different methods of work of vibrating rollers when compacting sandy soils, taking into account constantly changing conditions. The article reveals the dependencies of the main indicators in the production of compaction: the speed of the roller during compaction, the weight of the roller, the thickness of the compacted soil layer and the number of penetrations. The practical significance lies in the possibility of determining the optimal operating modes of various vibratory rollers during the compaction of sandy soils, which will determine the most productive and economically feasible parameters of their use

The article raises the problem of soil compaction. The analysis of the dependence of the compaction duration on various factors, such as: the type of soil, its humidity, its physical properties, as well as volume. The review of technologies of compaction applied at the moment in construction is given. The results of the technologies used in the construction of the project Yug. The second stage of construction of mnpp Volgograd-Tikhoretsk. GPS of Tinguta"". The study will allow construction companies to assess the economic feasibility of the use of soil compacting machines and mechanisms.
