International Bridge StudyWorkshop

June 14–15, 2011

iis

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 1980s.

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 Motivation >>

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 interventions/repairs.

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.
