The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, non- governmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president. The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. John L. Anderson is president. The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president. The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine. Learn more about the National Academies of Sciences, Engineering, and Medicine at www.national-academies.org. The Transportation Research Board is one of seven major programs of the National Academies of Sciences, Engineering, and Medicine. The mission of the Transportation Research Board is to provide leadership in transportation improvements and innovation through trusted, timely, impartial, and evidence-based information exchange, research, and advice regarding all modes of transportation. The Boardâs varied activities annually engage about 8,000 engineers, scientists, and other transportation researchers and practitioners from the public and private sectors and academia, all of whom contribute their expertise in the public interest. The program is supported by state transportation departments, federal agencies including the component administrations of the U.S. Department of Transportation, and other organizations and individuals interested in the development of transportation.

Maher, TRB Liaison AUTHOR ACKNOWLEDGMENTS This research report was prepared under NCHRP Project 12-108 by a research team lead by Modjeski and Masters, Inc., with Dr. Thomas Murphy as the Principal Investigator, Travis Hopper, Edward Wasserman, and Maria Lopez. The team includes Dr. John Kulicki independent consultant, Dr. Franklin Moon and Nick Romano of Rutgers University, Anne-Marie Langlois of COWI North America, and Dr. Naresh Samtani of NCS GeoResources, LLC. The late Dr. Dennis Mertz of the University of Delaware was a Co-Principal Investigator for the project, and was instrumental in the development of the methodology and approach that was implemented in this research. Any positive impact that the results of this research may have on the practice of bridge engineering will have been due to his foresight and guidance. The authors would like to thank all who helped in the development and execution of the project including: the project panel, who provided guidance and critical technical review, Jay Helsel of KTA-Tator, Inc., who provided key information regarding coating systems, Diane Long of Modjeski and Masters who provided editorial review, and the AASHTO member states and the state bridge engineers who provided responses to the surveys which contained valuable information on service life design practices.
