Effect of M-E Design Guide Inputs on Flexible Pavement Performance Predictions

This paper describes a study which focused on assessing the level of impact Mechanistic-Empirical Pavement Design Guide (MEPDG) input parameters relating to asphalt concrete, traffic, and climate have on specific damage models for typical flexible pavements. Two existing flexible pavements in Iowa were examined using the MEPDG software. For each pavement structure, 20 individual inputs were evaluated by studying the effect of each input on five different performance measures: 1) longitudinal cracking, 2) alligator cracking, 3) transverse cracking, 4) rutting, and 5) roughness. It was found that most input parameters influenced the predicted longitudinal cracking and total rutting, while alligator cracking, transverse cracking, and roughness did not show sensitivity to most input parameters. Researchers will next focus on comparing the predicted measures against the recorded pavement distress in the Pavement Management Information System (PMIS) database maintained by the Iowa Department of Transportation.
