Stabilization of road beds with fluoroanhydrite composition

Stabilized soil plays an important role in the formation of physical and mechanical properties of the road pavement. The quality of soil, its composition and properties can significantly affect the strength, durability and stability of road bases. This paper presents the results of the study of the properties of soils reinforced with the use of hydrofluoric acid production waste - fluoroanhydrite activated with sodium phosphate. The composition of the mixture was optimized to provide the required mechanical characteristics of the material, physical-mechanical and physical-chemical properties of the obtained composite material and its microstructure were investigated to assess the influence of the individual components of the mix on the formation of the matrix structure.
