Abstract
The issue of expanding the range of road-building materials used on forest roads is one of the most critical in the Russian Federation. This fact is connected with both the environmental and economic aspects, as well as with the wide geography of the country. A significant part of the forests are located in the permafrost zone, which requires the availability of materials with higher performance characteristics. The study considers the use of nepheline sludge as an alternative mineral binder in order to improve the physical and mechanical characteristics of the material for the construction of forest roads. X-ray phase, chemical, granulometric analysis of the material was carried out, as well as the study of the effect of the fractional composition of nepheline sludge on the physical and mechanical characteristics of the material. The materials presented in the study comply with standard in terms of their physical and mechanical characteristics.
