We studied basic physical properties and mineral composition of polymineral clays with different index of plasticity, common in the Volga region, whose clay components are represented by mixed-layered (mica–montmorillonite) minerals, hydromicas and chlorites in different quantities. The modification effect of studied soil cement with polycarboxylate superplasticizers on compressive strength, tensile strength in bending and frost resistance has been established. The polycarboxylate modifiers optimal content and effectiveness on soil cement have been determined. It is shown that the modification by polycarboxylate superplasticizers of soils with clay minerals and Portland cement content up to 10% makes it possible to achieve grade levels for strength—M40, frost resistance—F15 and the cement soils usage in bases and coatings structural layers of various pavement types, depending on road and climatic conditions.
