ROADWAY REHABILITATION AND ROAD USER COSTS--THE SECRET FORMULA FOR LOW COST

The author presents two basic performance curves, the pavement-life performance curve and the "effect of pavement condition on direct vehicle operating cost" curve to show that the lowest total cost for roadway transportation occurs when a good level of service is provided. For 75 percent of a pavement's life, a good-to-acceptable level of service is present, then quality drops rapidly and the cost of rehabilitation increases equally rapidly. The solution is to carry out rehabilitation at the lowest point on the cost curve which coincides with a good level of service. This basic information should be presented to the public and to decision makers in a clear, credible, persistent way, and sufficient funds to prevent excess cost will follow, says Sheflin. The road agency's job will then be to carry out rehabilitation at the optimum time. (Author)
