The Federal Highway Administration has developed a program to encourage the use of High-Performance Concrete (HPC) in bridges. As part of that program, the University of Washington and the Washington State Department of Transportation investigated the long-term behavior of a High-Performance Concrete (HPC) pretensioned concrete girder bridge. This report provides results from the program of girder design, and three years of monitoring and evaluation. A companion report provides results of the materials testing program (Barr et al. 2000a).
