A Pavement Design and Management System for Forest Service Roads: A Working Model. Final Report, Phase II
MetadataShow full item record
This is the second phase of a three-phase effort to develop and implement a pavement design and management system for low-cost, low-volume roads, in particular, Forest Service roads. The specific object of this phase is to develop working pavement design and management models and other information needed for optimization and decision making. Using the results of the Phase I conceptual study and a pre-existing program, an initial computerized working pavement design and management model was developed. During this phase, through continual coordination with various Forest Service engineers, this initial model was constantly modified to better consider the Forest conditions, design requirements and operating procedures. The resulting model, LVR, which is now ready for implementation and trial usage by the Forest Service during Phase III of this project, will design pavement structures based on an equal-effectiveness criterion for bituminous surfaced, aggregate surfaced or surface treatment roads. Two roads are considered to have equal effectiveness if they provide the same quality of service for the same length of time. Bituminous surfaced pavements are designed using a single failure criterion which is based on the AASHTO method currently in use by the Forest Service.
