RABIT was developed under DTFH61-08-C-00005 contract from the U.S. Department of Transportation - Federal Highway Administration (USDOTFHWA). The authors sincerely acknowledge this FHWA?s support through the Long Term Bridge Performance Program. The authors are also grateful to the Virginia Department of Transportation (VDOT) for its cooperation in providing access to the Haymarket Bridge. Finally, the authors are grateful to the previous or current research staff at Rutgers? School of Engineering and Center for Advanced Infrastructure and Transportation (CAIT), especially Professors Jingang Yi and Kristin Dana, research engineer Hooman Parvardeh, and former research staff and graduate students, Dr. Hung La, Ronny Lim, Parneet Kaur and Prateek Prasanna.

N2 - The performance of concrete bridge decks was identified as the top performance issue within the Federal Highway Administration’ (FHWA’s) Long Term Bridge Performance (LTBP) Program. To enable accurate, rapid and economical condition assessment of decks on a large number of bridges, the system named RABIT (Robotics Assisted Bridge Inspection Tool) was developed. The system concentrates on the characterization of internal deterioration and damage, in particular three most common deterioration types: rebar corrosion, delamination, and concrete degradation. For that purpose, the RABIT implements four nondestructive evaluation (NDE) technologies: electrical resistivity (ER), impact echo (IE), ultrasonic surface waves (USW) and ground-penetrating radar (GPR). Multiple NDE probes or large sensor arrays significantly improve the spatial resolution of the results. In addition, high resolution cameras image the surface of the deck for crack mapping and documentation of previous repairs. The paper provides an overview of the RABIT system and describes how the data collected by the system are being used in the development of more realistic deterioration and predictive models for bridge decks.
