Manual on Service Life of Corrosion-Damaged Reinforced Concrete Bridge Superstructure Elements

Size: 1.91 MB | Format: PDF | Quality: Original preprint | Publisher: NCHRP | Year: 2006 | pages: 72

The primary objective of this project was to develop a manual, for consideration and adoption by AASHTO, that provides step-by-step procedures for the following:
1. Assessing the condition of reinforced concrete bridge superstructure elements subjected to corrosion-induced deterioration.
2. Predicting the remaining service life of such elements.
3. Quantifying the service life extension for such elements expected from alternative maintenance and repair options.
The scope of work for this project was limited to bridge superstructure elements reinforced with black reinforcing steel and, to some extent, epoxy-coated reinforcing steel. It did not include prestressed concrete elements and other modified steels.
This manual is targeted toward engineers and maintenance personnel charged with maintaining the bridge structures.
This manual can be used by state and other highway agencies and adopted with or without modifications as guidelines for use within the organization.
