Maintenance Issues And Alternate Corrosion Protection Methods For Exposed Bridge Steel

This synthesis will be of interest to state department of transportation (DOT) bridge maintenance engineers, coating specialists, chemists, and researchers. Manufacturers and suppliers of corrosion protection products and systems for exposed structural steel on existing bridges will also find it of interest. This synthesis describes current practice regarding maintenance and protection strategies for exposed structural steel on existing bridges. NCHRP Synthesis 251, Lead-Based Paint Removal for Steel Highway Bridges ( 1997), provides a complementary and more in-depth treatment of maintenance issues involving lead-based paint removal. This report of the Transportation Research Board defines the maintenance management systems and decision making criteria used by transportation agencies for maintaining exposed bridge steel. Material selection criteria, surface preparation and application practices, quality control and quality assurance programs, and funding mechanisms are discussed in detail. The impact of recent and proposed environmental and worker protection regulations on current practice is reported. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search. Responses to the survey, Appendix C to this document, are published on the Internet as NCHRP Web Document 11.

TRB Special Report 256 - Managing Technology Transfer: A Strategy for the Federal Highway Administration addresses how the U.S. Department of Transportation's Federal Highway Administration selects research products for technology transfer and transfers those products to the highway industry, in particular the state and local agencies that own, operate, and maintain the nation’s highways.

"This synthesis will be of interest to state DOT bridge maintenance and construction engineers; regulators, consultants, and contractors involved with the removal of lead paint from bridges and structures; and structural coatings specialists, chemists, and researchers. This synthesis describes the current state of the practice for the removal of lead-based paint from existing highway steel bridges."--Avant-propos.
