Methods for Modifying the Properties of Clay Soils with the Inclusion of Organic Substances

One of the tasks of the national project “Safe and High-Quality Roads “ being implemented is the use of technologies based on the reuise of materials. This work is devoted to the analysis of existing methods of strengthening and stabilizing clay soils, with special attention to soils containing organic substances in their composition. The task is to assess the impact of binders and/or the most well-known stabilizing additives on clay soil, including those with a high content of organic substances. A comparison of the physical and mechanical characteristics of reinforced clay soils was made, while the most famous additives from various manufacturers are given. The consumption of mineral binders and additives when strengthening clay soils is indicated. The advantages of complex soil strengthening with the use of mineral binder (cement) and polymer additives are shown. The possibility of using soils with a high content of organic substances in the structural layers of road pavements has been proved. When modifying soils, it is necessary to take into account their genetic type, since it strongly affects the strength characteristics.
