BRIDGE INFRASTRUCTURE PRESERVATION

1. BRIDGE INFRASTRUCTURE PRESERVATION

2. CURRENT CHALLENGES • Significant Growth in CMV Traffic • Increased congestion and delay • Demand for larger and heavier vehicles • Mounting stress on infrastructure • Greater need for effective and efficient enforcement

3. CURRENT CHALLENGES • Bridge Infrastructure Deterioration • 72,500 U.S. bridges “structurally deficient” • $65.3 billion repair estimate • Inexact methods to reduce, refine, prioritize actions • Uncertainties in traffic loading • Uncertainties in bridge response

4. THE NETHERLANDS BELGIUM GERMANY FRANCE SWITZERLAND SLOVENIA BACKGROUND • 2006 European Scan Tour • Emerging technologies • Unconventional procedures • Novel data applications • Innovative funding mechanisms • Multinational harmonization

5. EUROPEAN APPROACH • Technology-based Policies/Procedures • Structural/safety assessment • Slovenia, France enhance the accuracy of bridge safety conclusions through direct measurements • Load testing • Slovenia uses “soft” load testing

6. SUPPORTING TECHNOLOGIES • Overheight Vehicle Detection System • Vehicle Profiler System • WIM Systems • In-road • Bridge • Dynamic Calibration Vehicle • Vehicle Identification System • Advanced Routing/Permitting System • Archived Records Database
