| Title of the article | Stabilization and strengthening of soils using the stabilizer “Status” |
| Abstract. | The widespread use of cohesive soils in road construction is constrained by the fact that their hydrophysical and physical-mechanical characteristics deteriorate when moistened. To solve this problem, the work on the use of the method of soil stabilization and strengthening with various binders and chemical additives, including stabilizers, is of the greatest relevance. To reduce the required amount of binders and improve the quality of organo-mineral mixtures, it is promising to use various additives such as surfactants and catalysts, including the stabilizer “Status” developed by the authors. The aim of the work is to study the effectiveness of the stabilizer “Status” in stabilizing and strengthening clay soils for road construction. The following tasks were solved: to establish the effect of the stabilizer “Status” on the compressive strength of clay soils during their stabilization; to determine the physical-mechanical properties of clay soils stabilized and reinforced with Portland cement with the addition of the stabilizer “Status”; to conduct pilot industrial implementation of the stabilizer in the construction of the roadbed and pavement on highways. Results. The stabilization of the soils of the roadbed with the addition of “Status”, at optimal content, provides the opportunity to increase the compressive strength of stabilized clay soils by an average of 7.0 – 12.0%. The physical-mechanical properties of stabilized and reinforced soils with the addition of the stabilizer “Status” correspond to the required regulatory parameters for a refractory loam with a plasticity of 14.0 and a clay particle content of 17.3%, which can be used in the roadbed and road structural layers of highways in climatic zones with alternating temperatures. Conclusions. The pilot implementation of stabilized and reinforced soils with additives of the stabilizer “Status” in the construction of the roadbed and pavement on highways in the Samara region and in other regions of the Russian Federation confirmed the effectiveness of the developed modifier to ensure the possibility of improving the properties of materials and reducing the cost of road construction. |
