Данный факт связан как с экологическим и экономическим аспектом, так и с широкой географией страны. Значительная часть лесных массивов находится в зоне вечной мерзлоты, что требует наличия материалов с более высокими эксплуатационными характеристиками. В исследовании рассматривается вопрос применения нефелинового шлама как альтернативного минерального вяжущего с целью повышения физико- механических характеристик материала для строительства лесных дорог. Проведены рентгенофазовый, химический, гранулометрический анализ материала, а также исследование влияния фракционного состава нефелинового шлама на физико-механические показатели материала. Представленные в исследовании материалы соответствуют ГОСТ по своим физико-механическим характеристикам</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нефелиновый шлам</kwd><kwd>шламогрунт</kwd><kwd>лесные дороги</kwd><kwd>β-двухкальциевый силикат</kwd><kwd>гидросиликаты</kwd><kwd>укрепление грунтов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nepheline sludge</kwd><kwd>slurry</kwd><kwd>forest roads</kwd><kwd>β-bicalcium silicate</kwd><kwd>hydrosilicates</kwd><kwd>soil strengthening</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Аринушкина Е.В.
