Sensitivity Analyses for Flexible Pavement Design with the Mechanistic–Empirical Pavement Design Guide. Introduction

This introduction to Circular E-C155 comments on the workshop that was developed to provide information for transportation agencies in the process of, or considering the implementation of, the interim AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). The workshop shared experiences from transportation agencies that have performed various sensitivity analyses using the MEPDG software, primarily related to flexible pavement analysis. The goal of the workshop was to communicate which input factors are important to the final pavement designs, so that agencies can focus their research accordingly during the implementation process.
