Bijan Khaleghi and Jerry Weigel, Washington State Department of Transportation The need for a superior and durable concrete capable of resisting environmental distress resulted in the development of high performance concrete (HPC) for bridge decks. This article focuses on the
CURING FOR HPC BRIDGE DECKS — BRING ON THE WATER!
Michael F. Praul, Federal Highway Administration As we take the next step in the evolution of concrete technology and move toward more widespread implementation of high performance concrete (HPC), we must realize that assuring successful application of concrete in bridge

TIA OFFERS HPC WORKSHOPS
Charles H. Goodspeed, University of New Hampshire As part of the national program to continue the implementation of high performance concrete (HPC) in bridges, a series of seven training modules will soon be available from the Transportation Industrial Alliance (TIA).
MISSOURI’S HPC BRIDGE EXPERIENCE
Tim Chojnacki, Missouri Department of Transportation In the fall of 1998, two companion bridges on Missouri Route 21 over Route M in Jefferson County were opened to traffic. The northbound bridge was constructed using prestressed concrete Igirders made of high
