CORROSION PROTECTION - CONCRETE BRIDGES

Table of Contents | Next

FOREWORD

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.

Other reports will summarize progress from Structures High-Priority Programs for: Geotechnical Engineering; Hydraulics/Scour; Seismic Protection; Corrosion Protection - Steel Bridges; and Timber Bridges.
