The primary purpose of the study was to add to the findings of a two-year pilot study on pavement monitoring. The investigation centered on monitoring equipment as well as monitoring methodologies. The long-term nature of the study permitted observations of pavement performance from essentially new, or rehabilitated pavements to a deteriorated state where rehabilitation was once again needed. Testing equipment ranged from high-speed profilometers to a simple six-foot straight edge. Results of the study show a typical slow increase in rutting, and relatively stable deflection values. A remarkably characteristic trend was found in pavement cracking, showing an exponential growth pattern. In the area of equipment it was found that because of lack of calibration, continuity in the database was not feasible.
