Performance of Jointed Concrete Pavements. Volume 5. Appendix B. Data Collection and Analysis Procedures

摘要

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), deflections, destructive testing (coring and boring), and weigh-in-motion (WIM) on selected sites. The 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 was used to evaluate and modify several concrete pavement design procedures and analysis models. The volume provides documentation of the data collection and analysis procedures used in the study. The field data collection activities, including deflection testing and coring/boring, are discussed, as is the weigh-in-motion (WIM) data collection procedures. Traffic computations and backcalculation methodologies are presented, along with the basis for the drainage is followed by an annotated bibliography of pertinent publications.
