  1. National Cooperative Highway Research Program (NCHRP) Research for Improved Highway Operations and Maintenance Report to the AASHTO Highway Subcommittee on Maintenance Louisville, Kentucky, July 2011 1

  2. NCHRP- National Cooperative Highway Research Program • An AASHTO program sponsored by state DOTs • Started in 1962 • Annual funding ~ $40 million/year • Contributes to advancements in all aspects of highways • 8 fields of research (Administration, Planning, Design, Materials and Construction, Soils and Geology, Maintenance, Traffic, and Special Projects • 25 Subject areas (e.g., economics, forecasting, pavements, bituminous materials, mechanics and foundations, snow andice control, maintenance of ways and structures, equipment, illumination and visibility, and special projects)

  3. NCHRP: Goal-Oriented Research • Responds to state DOT needs: DOTs and AASHTO committees propose research topics; SCOR selects projects. • Ensures applicability of the results: state DOTs and other sectors of the highway industry participate in monitoring the research. • Results are published by NCHRP (reports, digests, synthesis, CD-ROMs, and Web documents) or by AASHTO (guides/manuals, specifications, and test methods), and often adopted by state DOTs and other organizations.

  4. Scope of NCHRP Projects Related to Maintenance • Pavement Maintenance • Snow and Ice Control • Bridges and Structures • Roadside • Maintenance Equipment • Workforce Development • Etc.

  5. Three Types of NCHRP Projects(of Interest to the AASHTO Highway Subcommittee on Maintenance) • Research Projects Selected by SCOR once/year (March). • Research for AASHTO Standing Committee on Highways (20-07 projects) Selected by NCHRP Project Panel SP20-07 twice/year (May and October). • Synthesis of Information Related to Highway Problems Selected by NCHRP Project Panel SP20-05 once/year (May).

  6. Publication of Completed Projects ☺ Published by AASHTO ☺ Available on AASHTO Website ☺ Published in the NCHRP report series (as an NCHRP report) ☺ Summarized and made available on NCHRP Website ☺ Published in the NCHRP synthesis series (as an NCHRP synthesis)

  7. Published by AASHTO ☺ AASHTO Maintenance Manual for Roadways and Bridges (2007) ☺ AASHTO Guide for Snow and Ice Control (1999) ☺ AASHTO Guidelines for the Selection and Application of Warning Lights on Roadway Operations Equipment (2009)

  8. Recently Published NCHRP Reports ☺ A Framework for a National Database System for Maintenance Actions on Highway Bridges (NCHRP Report 668) ☺ Manual for Emulsion-Based Chip Seals for Pavement Preservation (NCHRP NCHRP Report 680) ☺ Determining Highway Maintenance Costs (NCHRP Report 688) ☺Decision Making for Outsourcing and Privatization of Vehicle and Equipment Fleet Maintenance (NCHRP Report 692)
