【 摘 要 】

The article considers the use of soils, treated with cement with Nicoflok polymeric-mineral composite, for replacing stone materials as the bases by the example of two variants of rigid and non-rigid structures. We carried out the laboratory studies of the polymer-cement-soil mixture, presented physical and mechanical properties of the soil samples, taken from the quarry and determined their grain distribution and physical and mechanical parameters of the cement used. In the course of the study, we determined the properties of the initial materials, their compliance with the GOST requirements, the indicators of the improved soil after 7 and 28 days of storage, according to the requirements of standard procedures. We tested the structure of a non-rigid base for strength, frost resistance and permissible elastic deflection strength, analyzed the structure based on the condition of shear stability in soil and analyzed the structure for bending tension. We determined the fatigue ratio for the rigid road structure and presented the results of calculating the dependence of the layer thickness on the fatigue ratio.
