                        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).
