International Bridge Study
June 14–15, 2011
IBS Motivation >>
A significant investment has been made into infrastructure and
bridge technology research, development and demonstrations by
Federal and State Governments in the US and abroad since the
Although there is a great need for objective and mechanistic
approaches to bridge evaluation, maintenance and repair, and there
are many aspiring technology providers, there has been very few
applications, if any, providing insight, knowledge and actionable
recommendations to the satisfaction of a bridge owner.
There is a lack of guidelines for bridge owners to help them decide
whether/which/when/why/how of technology leveraging. Those
guidelines that exist (AASHTO Manual for Condition Evaluation) are
dated and insufficient, and may not guarantee safe applications and
reliable results. There is a glaring lack of proper terminology.
IBS Objectives >>
Bring together a select group of international bridge experts to
demonstrate the most promising technology tools on the same
bridge in NJ. The NJ bridge exhibited a spectrum of bridge
performance concerns, defying common heuristic and empirical
solutions and requiring expert technology leveraging.
Demonstrate and document the best practices for technology
selection, integrative application, objective data and
information generation, and interpretation for effective
To develop (a) International Guidelines for Bridge Owners to
Assist in Technology Leveraging; (b) Best Practices for the
Selection, Application, Integration, and Interpretation of
Technology Tools.
