Abstract
A method for repairing eroded concrete rail ties. An abrasion resistant composition incorporating a curable binder is applied to the eroded rail seat and cured by the application of pressure and heat. A gas fired heating plate with a release surface is pressed onto the composition to force it into the eroded recess and cure it. The device incorporating the heating plate is clamped onto the rail clamp shoulders embedded in the concrete rail tie to enable pressure to be applied.
