Review of Initial Service Life Determination in Life Cycle Cost Analysis (LCCA) Procedures and in Practice

This report analyzes life cycle cost analysis (LCCA) and the methodology used to determine initial service life. A survey of state departments of transportation and a literature review were used to examine: the determination of initial service life; performance measures for the determination of actual service life; the first major rehabilitation activity; and pavement roughness at time of rehabilitation. Asphalt concrete and Portland cement concrete pavement sections in the U.S. and Canada in the Long-Term Pavement Performance (LTPP) program were investigated for: initial service life values; actual pavement age at time of first rehabilitation; type of rehabilitation; and climate zone. Results are discussed including that initial service life values being used in LCCA do not represent the actual pavement age at first rehabilitation for asphalt concrete pavements. The report concludes with recommendations for calculating LCCA initial service life in AC and PCC pavements.
