Abstract

A retro-reflective system for increasing the safety of a railroad crossing includes at least one railroad crossing panel. A sealer is applied to a prepared surface of the railroad crossing panel. An adhesive applied over the sealer after the sealer is partially cured adheres a retro-reflective material thereto. The retro-reflective material increases visibility of the railroad crossing. Anti-skid elements may also be applied over the adhesive, to provide enhanced traction for vehicles or pedestrians traversing the railroad crossing.
