Research – NCHRP Process Steps1. July – SCOR solicits problem statements from three sources.

• AASHTO member DOT’s• AASHTO Committee and Subcommittee Chairs• FHWA Administrator

2. September – FHWA and NCHRP evaluations are performed. NCHRP Panels are used for key areas such as bridges, materials, etc.

3. December – Continuing projects and new problem statements go to SCOR and the Research Advisory Committee (RAC) and are prioritized.

4. March/April – Final priority and program is developed by SCOR5. May/June - SCOR sends a report to the AASHTO Board of Directors

requesting approval of the program.

See address below for a complete overview of the NCHRP process http://www.trb.org/NCHRP/NCHRPOverview.aspx 82
