This report documents a study undertaken to validate the proposed pavement performance measures identified in the Federal Highway Administration (FHWA) Notice of Proposed Rulemaking (NPRM) issued in response to the Moving Ahead for Progress in the 21st Century Act, which included requirements pertaining to transportation performance management. To accomplish this objective, three major activities were carried out: (1) a literature review that yielded criteria for evaluation of the proposed performance measures and translation of distress data from the Long-Term Pavement Performance database to the pavement condition metrics used by the performance measures proposed in the NPRM; (2) a review and validation of performance measures over time, both within and between construction events, and against the thresholds identifying performance; and (3) an analysis of alternate pavement condition threshold values, the change in the metrics and overall pavement conditions over time, and the metrics driving the overall condition and performance.
