摘要:
A process of applying a protective coating to railroad crossties, telephone poles, and telephone pole crossties is provided. The protective coating includes a polymer or polyurea resin that is sprayed, brushed, or rolled onto the railroad crossties, telephone poles, and telephone pole crossties. Alternatively, the railroad crossties, telephone poles, and telephone pole crossties may be immersed in a tank containing the protective coating. A strengthening material including aramid fiber fabric may be disposed adjacent the railroad crossties, telephone poles, and telephone pole crossties or between layers of the applied protective coating to provide increased tensile strength thereto.
