Over the last few years, transportation agencies have had the opportunity to use AASHTO’s interim Mechanistic–Empirical Pavement Design Guide (MEPDG) software. This software allows users to assess the impacts of traffic, climate, materials properties, etc. on the predicted pavement performance. Several transportation agencies have begun the process of implementing the design process. However, many agencies are just starting the implementation process or are waiting to see the results from other states. As such, the Transportation Research Board Flexible Pavement Design Committee (AFD60) requested assistance from state agencies in collecting and disseminating information and results related to sensitivity analysis of flexible pavement designs performed by transportation agencies. A survey similar to the Federal Highway Administration (FHWA) MEPDG survey used earlier in the decade was circulated via electronic mail during the summer of 2009. The survey questions and summary of responses are provided in this presentation. Overall, there were 52 agencies that participated in the study, including 48 out of the 50 U.S. states. The other agencies were the District of Columbia Department of Transportation, Puerto Rico, FHWA Federal Lands Division, and Ontario Ministry of Transportation. A remarkable response rate of 98% was attained.
