New and innovative pavement performance measures and rating systems were developed and successfully implemented using pavement condition and distress data obtained from the Long-Term Pavement Performance (LTPP) database and the databases of three State transportation departments—Colorado Department of Transportation, Louisiana Department of Transportation and Development, and Washington State Department of Transportation. The new systems were used to calculate the benefits of various pavement treatments, determine the impacts of the pavement conditions in climatic regions on pavement performance, and assess the effects of design variables on pavement longevity. All analyses were conducted using MATLAB®-based computer programs that were specifically developed during this study. A preliminary method to estimate pavement performance based on a single data point was developed. Finally, the LTPP measured pavement deflection data were analyzed to determine whether the data could be used as pavement distress indicators. During the analyses, existing temperature-adjustment procedures were evaluated, and a global algorithm was developed that was applied to all deflection sensors in all climatic regions.
