A Life Cycle Cost Analysis (LCCA) is a technique used by many state highway agencies to evaluate the overall expected costs of competing pavement alternatives, primarily between asphalt and concrete designs. LCCAs consider initial construction costs, along with future anticipated costs such as maintenance and rehabilitation costs, as well as user costs. But what happens at the end of a pavement’s life, and how should that be properly accounted for in an LCCA? This webinar will focus on the best methods of addressing pavement end of life issues when conducting a LCCA, ranging from making certain that the remaining service life of a pavement is properly addressed, to understanding the importance of considering what actually happens to a pavement when it reaches its terminal serviceability, and how that needs to be included in an LCCA. Attendees will: • Learn the difference between residual value of a pavement versus its remaining service life value • Understand how to determine the remaining service life value of a pavement and the importance of applying that concept to all pavement layers • Understand the importance of assuring that the LCCA analysis period be long enough to make sure that one of the pavement alternatives reaches its terminal serviceability, and that the cost of the remediation be accounted for as a future cost during the analysis This webinar is RCEP approved.
