  • Abstract:
    The Illinois Department of Transportation (IDOT) received Innovative Bridge Research and Construction (IBRC) funds from the Federal Highway Administration (FHWA) for fiscal years 2000 and 2002. These funds were used to construct High Performance Concrete (HPC) bridge superstructures and substructures using various mix designs from 2000 through 2004. All the mix designs provided high strength and low permeability. These bridges have been examined over the years, and some bridges as late as 2011. The results of the bridge deck inspections indicate bridge decks constructed with HPC cracked as much or more than non-HPC bridge decks. The results yielded other information, but the most surprising fact was that in two cases it was suspected the coefficient of thermal expansion for a gravel coarse aggregate resulted in a significant amount of bridge deck thermal cracking. The report also includes the results of four bridge decks built in the early 1990’s using shrinkage-compensating concrete. These bridge decks were examined in 2008-2009 and showed less cracking than what is normally observed in the field. These results have prompted IDOT to perform more research in this area. The report also includes the results of one bridge deck constructed with synthetic fibers in 2009 that was examined in 2010.
