5. 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.
