This paper presents a methodology for quantifying increased maintenance and rehabilitation (M&R) costs due to delaying M&R action. The methodology used data collected from several U.S. Army installations. These data included (1) pavement performance measured in terms of the Pavement Condition Index (PCI), (2) structural history, and (3) detailed costs. The methodology is based on applying life-cycle cost analysis to determine the Equivalent Uniform Annual Cost (EUAC) for various M&R alternatives. This was repeated at different pavement condition levels. The EUAC analysis for each M&R alternative included pavement surface preparation cost, initial cost of the M&R alternative, and future annual routine maintenance cost. The results of this study showed that considerable savings can be achieved if pavement sections are maintained while they are good condition and are not allowed to deteriorate into poor condition.
