RABIT™ Bridge Deck Assessment Tool

RABIT Bridge Deck Assessment Tool

The Federal Highway Administration Long-Term Bridge Performance (LTBP) Program developed a multifunctional nondestructive evaluation (NDE) platform to enhance the assessment of bridge decks. The RABIT™ bridge deck assessment tool was developed to deploy a suite of NDE technologies simultaneously. [Read more]

Condition Assessment of Bridge Deck Using Various Nondestructive Evaluation (NDE) Technologies

Nondestructive evaluation (NDE) technologies were utilized to perform a detailed condition assessment of the deck with respect to corrosion, delamination, and concrete quality in the “Virginia Pilot Bridge.” This was the third assessment of this bridge deck over the last 5 years; previous assessments were performed in September 2009 and August 2011.

Long-Term Bridge Performance Program State Coordinators Map

State LTBP Coordinators

Federal Highway Administration (FHWA) has established an LTBP State Coordinators Group with one key bridge person from each State in the Nation, the Commonwealth of Puerto Rico, and the District of Columbia. [Read more]


What is LTBP?

The LTBP Program is a 20-year (minimum) research effort to collect scientific performance field data from a representative sample of bridges nationwide that will help the bridge community better understand bridge deterioration and performance. The products from this pro­gram will be a collection of data-driven tools, including predictive and forecasting models, that will enhance the abilities of bridge owners to optimize their management of bridges.

What is the Objective of LTBP?

The overall objective of the LTBP Program is to inspect, evaluate, and periodically monitor representative samples of bridges nationwide to collect, document, maintain, and manage high- quality quantitative performance data over an extended period of time. This will require taking advantage of sensing technologies and nondestructive evaluation and testing tools in addition to typical bridge inspection approaches. It will also require close collaboration among stakeholders, State transportation departments, academia, and industry to collect data that are available but not currently gathered into a single database by anyone in the bridge community. The LTBP Program is designed in part to collect critical performance data that are not available elsewhere and merge it with data gathered from available sources. [Read more.]
