    Abstract: In construction or repair of a railway road bed a base section of particulate matter is laid and consolidated with polymer: resin:solvent emulsion, a layer of ballast is added, the ties and rails are laid, and additional ballast is laid between the ties and at the ends of the ties to a height and width sufficient to produce a curb on top of the base section and outside the ties. This curb is then consolidated by treatment with this emulsion leaving the center strip and the layer of ballast immediately below the rails unconsolidated to facilitate subsequent leveling or repair.
