Paperback. Condición: New. Print on Demand. This book examines the effectiveness of creosote treatment in preserving two types of wood used in railway tie construction: jack pine and eastern hemlock. Historically, there has been scant reliable data available regarding these woods and their susceptibility to treatment, and this study provides crucial information for both the railways and companies engaged in timber maintenance. The author investigates various treatment processes, including the novel incision method, which involves making small incisions into the surface of the wood to facilitate penetration of the preservative. Meticulously conducted experiments demonstrate that this technique enhances penetration in both jack pine and eastern hemlock, particularly the latter species, which has proven difficult to treat using conventional methods. The book concludes that the incision method is highly effective, economical, and suitable for commercial-scale application.
