Forest road classification in Canadian industry in the late 1960s was uncoordinated and chaotic. Local requirements varied so widely that there were no common grounds for industry-wide standardization. Study showed significant differences underlying the design philosophies of public and forest roads. In particular, forest road design was closely linked to production requirements wherein the roads have a finite life and the objective is clearly lowest cost. A new system of describing forest roads was proposed that consists of five-part designations assembled from symbols representing the design conditions or service requirements of these roads. The symbols represent maximum axle load, desired vehicle speed, availability, daily traffic, and anticipated life. Through proper manipulation of the symbols a designation may be assembled to describe almost any type of service a forest road (or public highway) might provide. The system was critically reviewed and subsequently accepted as a standard by the Logging Operations Group of the Canadian Pulp and Paper Association.
