Research on Frost Protective Layers for Railways

Foam glass aggregates, a granular material made from recycled glass of various origins, are among these new products. Problems of managing glass residue have several origins: contamination from the recovery step, ineffective grading technology and low economic value of the final product. These problems limit the incentives to invest in the recycling of waste glass. Test study of frost protection layer structures was performed on Russian Railway Research Institute experimental track in Moscow. Cellular materials used for protection layers were FGA ballast and XPS panels. Obtained results show that FGA ballast can be used in protective layer. It is suitable for installing on wetted and less stiff subgrade sections (with a deformation modulus less than 50 MPa). Installation of geotextile at the top and bottom of protection layer is advised to achieve requires stability and water erosion tolerance.
