This presentation gives an overview of the research underway at the Virginia Transportation Research Council related to traffic and materials inputs for use with the Mechanistic– Empirical Pavement Design Guide (MEPDG). The presentation lists and shows examples of those traffic and materials inputs that are considered significant with respect to the MEPDG-predicted pavement conditions. Various methods to determine the significance of the inputs (by statistical or practical consideration of the predicted pavement conditions) are discussed. Two methods of calculating a normalized difference statistic are presented along with a brief description of regression analyses that could serve as examples for statistical-based analysis. Practical-based methods were suggested to include consideration of the time to failure as it relates to the timing of pavement maintenance activities. The presentation discussed preliminary findings in terms of a comparison of the predicted pavement condition to expected values based on field experience. The need for local calibration was discussed as a future need.

Editor’s Note: Virginia Transportation Research Council is now the Virginia Center for Transportation Innovation and Research.
