Annotation: In the pavement construction, the base layers have the greatest thickness. Therefore, their construction is associated with a large consumption of building materials. At the same time, the base layers operate under more favorable conditions when compared with coatings, which makes it possible to widely use local materials and industrial wastes for their construction. The feasibility of using them is justified by technical and economic calculations, taking into account the possible decrease in the service life of pavement as a result of the refusal to use standard imported materials.
