13. Long-Term Bridge Performance (LTBP) Program
Definition of Bridge Performance:
Bridge Performance Encompasses How Bridges Function and Behave Under the Complex and Interrelated Factors they are Subjected to Daily:
Traffic Volumes
Loads
De-Icing Chemicals
Freeze-Thaw Cycles
Environment
Extreme Events
Method of Design
Construction
Materials
Age
Maintenance History

14. Long-Term Bridge Performance (LTBP) Program
Vision: The LTBP Program will Serve as the National Platform for Strategic Long-Term Investigation of In-Service Bridge Performance.
Mission: Foster Improved Bridge Performance, Health, Stewardship, and Management Through the Analysis of Data Collected Over a 20-Year Period on a Large Representative Sample of U.S. Highway Bridges. To achieve this, the Program is Designed to Produce and Support Improved Deterioration Models, Reliable Life-Cycle Cost and Forecasting Models, Design Procedures, and Decision-Making Tools.

17. Initial East Coast N/S Bridge Corridor

18. Long Term Bridge Performance Program
“Robot”
Remote controlled
Cameras
GPS
4 NDE technologies
Deployed on 24 bridges
3 high-resolution cameras capture holistic deck-surface images to show deck cracks, and the lengths and widths of the cracks as small as 1 millimeter. 360-degree images also can show the presence and condition of barriers, poles, curbs, and other surrounding hardware.
GPS precisely tags condition data with exact location using global coordinates.
Electrical resistivity device enables bridge inspectors to measure the level of corrosion within the deck.
14 impact echo devices are a seismic or stress-wave technology that are used to find defects and anomalies in concrete such as delamination and debonding, including depth, spread, and severity.
6 ultrasonic surface wave sensors are used to assess the quality and modulus of elasticity or strength of the concrete deck.
GPR provides a qualitative condition assessment of the deck and can detect apparent or suspected deterioration such as delamination or corrosion. The system uses 32 dense array, ground-coupled antennas for high-spatial resolution.
Integrates data into a 3-D visualization that shows the exact shape, width, depth, and location of damages.

15 of 23 metrics were revised and sent out to Divisions on 4/1/2013

22. NBI Data Quality
Trends show results of significant efforts to reduce errors
Error = bad or missing data
> 60 Million pieces of data in NBI
Number of Errors
2009
2010
2011
2012
115,811
20,284
6,967
4,155
Further clarification: Bad data includes values that are coded that are out of the range of assigned codes for a specific item, or data that does not pass certain reasonableness cross checks such as the bridge deck with curb to curb being larger than the bridge deck with out to out. We acknowledge that there are exceptions so some of these cross checks because of unusual structure configurations.
Further clarification: Missing data is values that are not submitted for required items to be coded for highway bridges. A check is made that the bridge is a highway bridge before issuing an error. For instance if a pedestrian bridge is submitted we would not expect to see a functional classification or certain other information.
