A Tool for Estimating Impact of Construction Quality on Life Cycle Performance of Pavements

Almost every constructed road develops distresses randomly in different subsections of the pavement. One reason for the random development of distress is the variability in construction quality. As such the goal in this project is to devise a tool that can be used to identify and minimize variability in material properties that impact the performance of the pavement to ensure a performance period compatible with the expected life of the pavement. With that framework, structural models that predict performance of pavements and material models that relate construction parameters to primary design parameters were identified. Finally, a statistical algorithm that relates the impact of each construction parameter to the performance of a pavement is incorporated into the algorithm. The implementation of an effective performance-based construction quality management requires a tool for determining impacts of construction quality on the life-cycle performance of pavements. This report presents the final efforts in the development of a statistical-based algorithm that reconciles the results from several pavement performance models used in the state of practice with systematic process control techniques. Guidelines for the short- and long-term implementation of this methodology are included in this report.
