The research team will conduct the work in two phases to achieve the objectives of the Long-Term Bridge Performance (LTBP) Program. These phases are:
Draft Pilot Study Plan
The purpose of the Pilot Study was to validate protocols for assessment, data collection, and management; to develop partnerships and coordination with the State DOTs more fully; and to ensure that all of the components needed to achieve the long-term objectives of the LTBP Program were considered before embarking on the Long-Term Data Collection phase of the Program.
Pilot Study Execution
The Pilot Study used draft protocols to gather data on seven different types of bridges in Florida, New Jersey, Virginia, California, Utah, Minnesota, and New York. The Pilot Study provided many useful comments that are currently being used to update the protocols.
Completion of this Pilot Study has resulted in the LTBP Program having a better understanding of each component of the Long-Term Data Collection phase of the Program.
LTBP Program Data Collection - Ongoing
As the Pilot Study has been completed , the contractor has commenced collecting data in two clusters in the Mid-Atlantic States. Data collection in these clusters began in March 2013. More information can be found here and here.
RABIT™ Bridge Deck Assessment Tool
The Federal Highway Administration (FHWA), in conjunction with Rutgers University’s Center for Advanced Infrastructure and Transportation (CAIT), developed a multifunctional nondestructive evaluation (NDE) platform to enhance condition assessment of concrete bridge decks. The RABIT™ Bridge Deck Assessment Tool was developed to deploy a suite of NDE technologies simultaneously.
