Identification and Determination of Distress Levels and Rehabilitation Cycles

The objectives of this study are to: (1) recommend a distress identification process for major distresses to be used in pavement performance models; (2) establish a threshold for rideability and distress thresholds for fatigue cracking, transverse cracking, rutting, faulting, etc; (3) identify and monitor calibration sites for evaluation of the NCHRP project 1-37A performance prediction models; and (4) perform an experimental life cycle analysis to determine the optimum design strategies based on existing pavement conditions traffic, treatments, and rehabilitation cycles.
