Investigation of the effect of water repellents on the rolling border and the yield stress of clay soils of the base and subgrade of the road

Abstract

<jats:p>During the construction of roads, the main factor affecting the operational characteristics of a linear facility is the climatic conditions of a particular area where the future road will pass. In the article, the authors consider the problem of building roads on weak soils with insufficient strength characteristics, such soils cause difficulties in the design and operation of the structure. The purpose of this study is to change the physical properties of cohesive soils to increase their strength characteristics. The authors systematized information on existing methods for stabilizing clay soils of the base and subgrade of the road. The results of experimental laboratory studies performed by the authors of the article on the influence of water repellents on the physical properties of clay soil are presented. According to laboratory studies, it can be concluded that with the optimal selection of hydrophobic materials, it is possible to increase the bearing capacity of soft soils, which in turn will lead to an increase in the technical and operational characteristics of the structure and an increase in turnaround times. The main conclusions are formulated based on the analysis of laboratory tests.</jats:p>
