PERFORMANCE OF JOINTED CONCRETE PAVEMENTS. VOLUME I - EVALUATION OF CONCRETE PAVEMENT PERFORMANCE AND DESIGN FEATURES. INTERIM REPORT

A major national field and analytical study 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), deflection, 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 brief introduction to the data collection activities and presents a description and performance evaluation of the 95 pavement sections included in the study. Documentation is presented on the effects of the following design features on concrete pavement performance: slab thickness, base type, joint spacing, reinforcement, joint orientation, load transfer, dowel bar coatings, longitudinal joint design, joint sealant, tied shoulders, and subdrainage.
