Proposed AASHTO Guides for Bridge Preservation Actions
Many transportation departments have significant practical experience with bridge
preservation and have developed conclusions regarding the effectiveness of bridge preservation
actions based on those experiences. However, limited efforts have been made to
identify, measure, evaluate, and document the short- and long-term performance of
specific bridge preservation actions.
The TRB National Cooperative Highway Research Program's
NCHRP Research Report 950:
Proposed AASHTO Guides for Bridge Preservation Actions
presents the development of two AASHTO guides for bridge preservation, including a
general guide to preservation of highway bridges and a guide to preservation of highway
bridge decks.

Appendix B: Summaries of Information from State DOTs.
