Full-Depth Precast Concrete Bridge Deck System: Phase II

Status:  Complete
Report Date:  10/31/2012


Researchers evaluated the field performance of Precast Composite Slab Span System (PCSSS) bridges from three generations of design by conducting detailed deck crack mapping and core analysis as well as by analyzing strain data from a first-generation bridge instrumented during construction in 2005. Field inspections indicated that with some anomalies, the changes made between each PCSSS design generation generally improved performance. However, third-generation bridges still had significant issues with deck cracking. MnDOT is still working to address this problem and is currently limiting the use of PCSSS bridges.
