Methodology |
|
| 3.1 | Use the segmentation and numbering system for the superstructure (FLD-OP-SC-002, Structure Segmentation and Element Identification System) so defects can be located and noted by the unique element identifier. | |
| 3.2 | Use FLD-OP-SC-003, Determination of Local Origins for Elements, to establish a local origin on each element. | |
| 3.3 | Use the data collection grid (FLD-OP-SC-001, Data Collection Grid and Coordinate System for Bridge Decks) to locate defects on the deck. | |
| 3.4 | Use the following protocols for finding defects and recording characteristics: | |
| 3.4.1 | Deck and superstructure: | |
| 3.4.1.1 | For potential spalls and delaminations on the deck: FLD-DC-VIC‑003, Concrete Deck—Spalls and Delamination. | |
| 3.4.1.2 | For each instance of spalls and delaminations on the superstructure: FLD-DC-VIC-004, Concrete Superstructure and Substructure—Spalls and Delamination. | |
| 3.4.1.3 | For each instance of cracking: FLD-DC-VIC-005, Concrete—Cracking. | |
| 3.4.1.4 | For each instance of abrasion: FLD-DC-VIC-006, Concrete—Abrasion. | |
| 3.4.1.5 | For each instance of sulfate attack: FLD-DC-VIC-007, Concrete—Sulfate Attack. | |
| 3.4.2 | Bearings: | |
| 3.4.2.1 | FLD-DC-VIS-001, Elastomeric Bearings. | |
| 3.4.2.2 | FLD-DC-VIB-002, Rocker Bearings. | |
| 3.5 | Documenting defects: | |
| 3.5.1 | Take photographs of defects using FLD-DC-PH-002, Photographing for Documentation Purposes, and create a photo log. | |
| 3.5.2 | Use sketches as needed to document defects and supplement the photographs. | |
| 3.6 | Storing data, documents, and images: | |
| 3.6.1 | FLD-DS-LS-001, Data, Document, and Image Storage—Local, for local storage. | |
| 3.6.2 | FLD-DS-RS-001, Data, Document, and Image Storage—Remote, for remote storage. | |
| 3.7 | Reporting: Transfer all metadata, data, documents, and images to Federal Highway Administration (FHWA), and/or upload all metadata, data, documents, and images into the Long-Term Bridge Performance (LTBP) Bridge Portal. | |

Commentary/Background |
|
| 6.1 | This protocol provides guidance for planning the detailed visual inspection of a concrete bridge deck and superstructure that consists of reinforced or prestressed concrete members as well as a reinforced or prestressed concrete deck. | |
| 6.2 | A bridge superstructure is that portion of a bridge that receives and supports traffic loads (distributed by the bridge deck) and, in turn, transfers these loads to the bridge substructure, via the bridge bearings. A concrete superstructure can consist of girders (such as American Association of State Highway and Transportation Officials (AASHTO) standard Type I though VI I-girders, AASHTO Pavement Condition Index (PCI) standard bulb tee girders, AASHTO/PCI standard pretensioned spread or adjacent box beams, specific State standard pretensioned concrete I‑girders or bulb-tee girders, pretensioned U-beams, cast-in-place posttensioned box girders, and segmental girders), diaphragms, and girder ends made continuous for a live load. | |
| 6.3 | Bearings are considered elements of the superstructure. | |
