CORROSION PROTECTION - CONCRETE BRIDGES |
The Federal Highway Administration recognized the problem of premature corrosion of reinforced concrete bridges in the early 1970's and established corrosion protection as one of its high-priority areas (HPA's) for research.
This report summarizes the research performed over the last 15 to 25 years of developing various cost-effective corrosion protection systems for both new structures and rehabilitating existing salt-contaminated, reinforced and prestressed concrete bridges.
Other forthcoming reports from Structures HPA's are: Geotechnical Engineering; Hydraulics/Scour; Seismic Protection; Corrosion Protection-Steel Bridges, and Timber Bridges.
This report will be of interest to owners, bridge engineers, consultants, and designers of reinforced and prestressed concrete bridges who are involved in the design, construction, maintenance, and rehabilitation of these structures.

16. Abstract
Premature corrosion of reinforcing steel has caused many
concrete bridges in the United States to deteriorate before their
design life was attained. Recognizing the burden that reinforcing
steel corrosion imposes on natural resources, the Federal Highway
Administration established Corrosion Protection for Concrete
Bridges as one of the high-priority areas (HPAs) in its Structures
Research Program. This HPA had two main objectives: (1) To develop
effective and economical methodologies for arresting or reducing
the extent of steel corrosion due to chloride-contamination of
concrete bridges, thereby reducing maintenance costs of existing
concrete bridges and minimizing interruption to traffic and, (2) To
develop sound design and construction practices and materials for
preventing corrosion of reinforcement in new structures, hence
minimizing future deterioration. To meet these objectives, several
research programs were developed and pursued in this HPA. This
report summarizes the progress made through research efforts
conducted under these programs.
