Department of Transportation, Federal Highway Administration
The Federal Highway Administration (FHWA) selected WJE to provide engineering services for the development and operation of the Nondestructive Evaluation (NDE) Validation Center, a national center dedicated to the advancement and validation of nondestructive technologies with highway applications.
WJE developed the test plan prepared by the New York Department of Transportation (NYSDOT), which called for monitoring of strain, load, deflection, and rotation. Five deteriorated, prestressed concrete box beams from a bridge in New York State were removed to achieve these objectives and were transported to the FHWA facilities for testing under controlled load conditions. WJE tested a severely deteriorated beam to initial cracking and to ultimate failure. Several severely deteriorated beams repaired with composite laminates were tested to initial cracking and ultimate failure. Based on this testing, WJE developed recommendations for surface preparation and application of FRP to strengthen deteriorated box beams.
