摘要

A method for repair and preventive maintenance of railroad ties by application of a polymer system to the surface of the rail seat. The polymer system is cured by irradiation with ultraviolet light to fully cure or partially cure the polymer. The polymer system may be used in conjunction with a tie pad that is capable of transmitting ultraviolet light to permit curing of the polymer.
