PREVENTIVE MAINTENANCE VERSUS RECONSTRUCTION: LIFE CYCLE COST ANALYSIS OF VARIOUS OPTIONS

Life cycle cost analysis is increasingly being recognized by public agencies as an effective tool to assist in the selection of construction, maintenance, and rehabilitation treatments. The Federal Highway Administration has developed a life cycle cost analysis methodology that will likely become the standard in the industry in the USA. The methodology can be used to evaluate the life cycle costs strategies including preventative maintenance, rehabilitation, and reconstruction. For preventative maintenance treatments to be more widely accepted, they must not only extend the life of the existing pavement, but also be shown to be cost effective, i.e., lower life cycle cost than the alternates. This paper presents: 1) an identification of preventative maintenance treatments and their benefits; 2) a description of the life cycle cost analysis process utilized in this study; and 3) comparative results that evaluate the life cycle cost for pavements that receive preventative maintenance treatments applied early on in the life of the pavement compared with those that receive only major rehabilitation/ reconstruction strategies. The findings indicate that preventative maintenance at early stages in a pavements life is cost effective in all of the scenarios studied. However, the reader should be aware that the estimated lives and costs used in this study are based on presently available information and engineering judgment. Deviations from these values could affect the final conclusions.
