Abstract: A method for maintenance of railroad wood ties is presented herein. The wood filler composition used in the method is applicable for filling holes or gaps in wood to stabilize wood structures. The composition comprises at least unintahite, also known as asphaltum or Gilsonite, and sand. The composition may further comprise a water repellant and a wood preservative. The composition is non-carcinogenic. The method comprises filling a hole with the dry composition described herein. The wood member may be a railroad tie and using an appropriate filling device, at least two holes, or at least four holes may be filled at one time.

Abstract: A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.
