Studies have investigated the use of slaked lime in strengthening slurry of the sludge-ground and ash-ground mixtures in order to impart a higher strength to the crystal lattice, as well as to accelerate the hardening processes by reducing the acidity of the medium. The results of the exploratory study on the interaction of sandy soil with mineral binders, as well as the results of the study of the physico-mechanical characteristics of samples of ash-sand mixture with slaked lime and the study of the physico-mechanical characteristics of samples of nepheline sludge soil mixed with slaked lime are presented. The obtained results confirm that the use of localized soils reinforced by mineral binders, including industrial waste, is economically feasible, which will allow the development of forest roads infrastructure Recycling of industrial waste in significant volumes in forest road construction will reduce the area of storage sites, thus is a priority from the point of view of ecology.
