Existing methods for assessing the plasticity of soils are labour-intensive, and yield the results of low quality. Due to the importance of this parameter for determining the strength of road beds when designing the construction of railways and highways, the development of new efficient methods for its reliable determination is of great importance. In this paper, we propose a method for solving this problem based on the correlation of mechanical and electrical properties of cohesive soils by the example of soil-forming minerals of montmorillonite and kaolinite
Keywords: layered aluminum silicates, soil plasticity, plastic and liquid limits, absorption, swelling, electrical measurements, correlation of mechanical and electrical properties
