The presenters will answer all questions at the end of the webinar/demonstration as time permits. Questions not answered because of time, will be responded to separately.

Process for Enhancing the Software: Suggested revisions are received from users and AASHTO members. Pavement ME Design Task Force monitors on-going/completed NCHRP, FHWA, and pool fund projects applicable to the MEPDG. Pavement ME Design Task Force members review and prioritize all potential suggested revisions and enhancements. Moderator: Overviews the activities of the task force for deciding what enhancements get done and turns presentations back to Chad.
