PAVING PROBLEMS OUTLINED ON CHESAPEAKE BAY CROSSING

New pavement on a deck of the Chesapeake Bay Bridge was under par as a result of a number of mistakes, requiring the redoing of part of the job and leading officials to re-think the next phase. The first phase, where there were problems, involved overlays on 95 spans totaling 12,400 feet and deck replacement spans on 3,900 feet. Work began in 2002 but cracks appeared in some of the repaved sections the following year, becoming more widespread in 2004, accompanied by some de- lamination. Tests also showed some decay on the underside of the deck, though the two are not linked, necessarily, officials said. The problems seem to be concentrated in the 6.5-in.-thick portions of the deck, which make up two-thirds of the bridge. There also appear to have been shortcuts in order to meet tight deadlines, including doing pavement work in temperatures lower than the minimum usually allowed.
