Resource-Efficient Designs and Organizational-Technological Solutions for Reinforcing the Subgrade in Sandy Soils

Abstract

This article examines current issues in enhancing the stability and load-bearing capacity of the subgrade for transport structures built in the complex engineering and geological conditions of sandy soils. It also analyzes the main deformation factors inherent to desert regions, including wind erosion and low soil cohesion. The paper proposes a set of resource-saving structural elements and organizational-technological solutions based on the use of modern geosynthetic materials and methods for stabilizing local barchan sands. These proposed technologies make it possible to significantly reduce transportation costs for imported soils and to minimize environmental damage. The practical significance of this work lies in the development of effective process flow diagrams that ensure the durability of the subgrade while optimizing material and technical expenditures.
