High Performance Concrete Bridge Decks Revisited

This article presents a brief review of 19 bridges constructed with high performance concrete. These bridges were all constructed after the 1993 Federal Highway Administration national program to implement the use of high performance concrete in bridges. The authors report on bridge deck performance and cracking after inspections conducted after the bridges had been in service for 5 to 10 years. The bridges are located in different climatic regions in the United States and use three different types of superstructures: precast, prestressed concrete beams with a full depth, cast-in-place concrete deck; precast, prestressed concrete beams supporting precast, prestressed concrete deck panels with a partial depth, composite cast-in-place concrete deck; and adjacent precast, prestressed concrete box beams with or without a cast-in-place concrete deck. The inspections included a visual survey and a detailed crack survey to document the number, length, and width of the transverse, diagonal, and longitudinal cracks on each deck. The authors report the specific findings, then conclude that a high performance concrete mixture, used with appropriate construction practices, will result in lower crack density. Overall, the review of these bridges show that the HPC in both decks and girders performed well.
