The paper discusses the use of nepheline sludge at the Pikalyovo alumina plant, characteristics, properties and its work performance in the constructive pavement layer during its life cycle. We consider the technique used in constructing the road layers with the use of this material. The issues of microcrack formation in sludge ground bases under the influence of loads from vehicles and weather and climatic factors are considered. The process of self-healing of damaged structural bonds in the structure layer is explained.
