THE COST OF MAINTAINING THE AUSTRALIAN NATIONAL HIGHWAY SYSTEM

This paper discusses the objectives of the Australian national highway system, presents statistical information and describes the application of the life cycle costing technique to the pavement evaluation. The work is based upon an earlier study undertaken by the Bureau to develop a life cycle costing model, which in turn incorporated research undertaken by the World Bank. Details of that work are contained in the Bureau publication Pavement Management: Development of a Life Cycle Costing Technique. The work documented in this paper used inventory information on all of the 16,000 kilometres of national highway, which was supplied by all state road authorities, and assessed the maintenance requirements by computer processing this information using the life cycle costing model. All pavements were assessed for a simulated 40- year period. This work examined the national highway system at a strategic level rather than at a micro level and therefore site-specific planning will still be required to determine the optimum maintenance project and its scheduling at any given location. This Bureau work has provided an estimate of the average annual maintenance requirement for each major link of the system as well as an estimate of the change in maintenance requirements over future years. The report comments on the likely rise in the pavement maintenance requirements as first the older, then the more recently constructed sections of the highway begin to deteriorate. The report has provided information for government policy makers, road maintenance managers and for road users.
