The study of the physical and mechanical properties of frozen soil has a great importance in the construction and operation of engineering structures in the conditions of the Far North. This makes it possible to take into account frozen soil features when designing and ensuring the safety of structures. This article discusses the mobile laboratory (ML) as a technological tool for the study of frozen soil in various climatic zones. Frozen soil is environmental complex with the constant presence of unfrozen water; its study is becoming more relevant due to climate change. The operation of the ML includes carrying out scientific work, solving engineering tasks and improving the quality of initial data for design. ML provides the opportunity to work in various geographical conditions and fast replacement over long distances by railway, road and water transport. ML can be easily transported to research sites: remote, rural or urban areas. It allows conducting research nearby of place of engineering survey. Based on the results of ML operation, authors concluded that the simultaneous presence of 3-5 employees in the laboratory complex makes it possible to distribute the labor resource potential in the most efficient way. Recommendations on the choice of its optimal ML location are given, considering the provision of operational maintenance and repair of equipment. The map of ML locations is presented. Physico-mechanical tests of frozen and dispersed soils according to set of rules SP 25.13330.2012 are listed.
