Abstract:A major national field and analytical sudy has been conducted into the effect of various design features on the performance of jointed concrete pavements. Extensive design, construction, traffic, and performance data were obtained from numerous experimental and other concrete pavement sections throughout the country. Field data collected and analyzed included distress, drainage, roughness, present serviceability rating (PSR), deflections, destructive testing (coring and boring), and weigh-in-motion (WIM) on selected sites. This information was compiled into a comprehensive microcomputer database. Projects were evaluated on an individual basis and then compared at a national level to identify performance trends. The performance data were used to evaluate and modify several concrete pavement design procedures and analysis models. This volume provides a broad overview of the work performed in this study. Summaries of the effect of various design features on concrete pavement performance are reviewed and performance trends identified. The accuracy of various prediction models and analysis methods are examined using the field performance data. From that evaluation, new prediction models were developed and a cost-effectiveness evaluation was performed.
