The article analyzes the use of chemical reagents to prevent winter types of slipperiness on cement-concrete roads. The characteristics of the formation of slipperiness on the surface of cement concrete coatings, taking into account changes in temperature and relative humidity, have been studied in depth. The authors determined the salt-resistant characteristics of cement concrete coatings in laboratory conditions and established their strength properties depending on the concentration of solutions. Based on these data, the maximum permissible norms for the distribution of chemical solutions and the concentration of solutions are determined. Also, as a result of field and laboratory conditions, the types of reagents applicable to cement-concrete roads have been established.
