Best Practices for Determining Life Cycle Costs of Asphalt Pavements

Tuesday, June 18, 2019 - 18:30

State highway agencies (SHAs) continually face important financial decisions when planning a new or reconstructed highway. For example, what is the initial investment for the highway? How much is needed periodically to maintain the highway in good pavement condition? What materials should be used to build the pavement? The answers to these questions may require a life cycle cost analysis (LCCA) based on the time value of money concept to assist in the final decision. To help SHAs and other agencies conduct such an analysis, this report provides best practices for properly determining inputs for use in their LCCA procedures and calculating the life cycle costs of pavement alternatives. The report is of immediate interest to engineers in SHAs, consulting firms, and the paving industry with responsibility for conducting LCCA as part of the pavement type selection process  This report from the US National Center for Asphalt Technology is available at http://eng.auburn.edu/research/centers/ncat/files/technical-reports/rep19-03.pdf
