The structural capacity of a pavement has been shown to be a good indicator of the required maintenance and expected performance of pavements. However, results in the literature provide few indices for rigid and composite pavements.
This study developed an index that produced promising results for use with composite pavements. The index relates deflection measurements to the performance of the pavement. Limited conclusions could be drawn from the results of rigid pavement testing due to the limited sample size and scope of the available data. The report presents steps for including the structural indices in pavement evaluation and management processes and a tool that can be used by engineers to calculate the structural indices for flexible and composite pavements based on defined input parameters.
A number of recommendations for implementation are made based on the findings of this study.
