Abstract
A concrete pavement evaluation system (COPES) has been developed for direct use or as a guide for the creation of similar systems tailored to the specific needs of users. COPES provides a framework and procedures for collecting historical and field data on the charactistics and performance of in-service portland cement concrete pavements. Data collected in six states using this system were analysed to demonstrate the potential applications for such data analyses in examining the design, construction, maintenance, and rehabilitation of concrete pavements.
