2.3.4 Survey of Bridge Maintenance Repair and Rehabilitation (BMRR) Practices
A comprehensive survey carried out by FHWA in the year 2000 brought to light a host of
issues. The most common rehabilitation activities are related to:
1. Deck slab, bearings, and deck joints.
2. Cleaning, washing, and flushing; replacement of deck joints.
3. Deck patching and overlays.
4. Deck crack sealers and surface sealers.
5. Painting steel to prevent corrosion (Figure 2.13).
