In 2007, nine states in the north-central region proposed to meet and share their expertise, challenges and accomplishments toward successful implementation of the Mechanistic– Empirical Pavement Design Guide (MEPDG). The Federal Highway Administration's (FHWA’s) Design Guide Implementation Team (DGIT) agreed to sponsor the meeting, and the National Center for Asphalt Technology (NCAT) and the Concrete Preservations Technology (CPTech) Center facilitated the February 2008 2-day event. Based on the success of the north-central meeting, FHWA’s DGIT sponsored four additional regional meetings in late 2008 and early 2009 to cover the balance of the country. All five meetings were planned independently, but a common agenda emerged. Each meeting started with a general overview of individual states’ MEPDG implementation plans. The second session examined general implementation issues, like “how to calibrate” the performance models (empirical transfer functions) and “how to coordinate” the effort of multiple department of transportation (DOT) offices. The third session allowed the participants to examine more specific technical details regarding traffic and material inputs. The meeting ended with a discussion of software limitations and regional challenges and opportunities. This report summarizes the limitations, challenges, and opportunities identified by the participants.
