Paving Problems Outlined On Chesapeake Bay Crossing
At least five separate errors combined to badly damage sections of the recently resurfaced parts of the Chesapeake Bay Bridge, according to a new report.
The concrete resurfacing project was done on the bridge's thin deck, which also contributed to the delamination woes, according to an independent review panel. But its report also cited inadequate surface preparation of the deck substrate, use of an epoxy material applied to the substrate, use of silica-fume concrete mixtures, placement of concrete in cold temperatures and use of a sprayed curing compound.
