Reducing Cracking in New Concrete Bridge Curbs

The concrete curbs on several new and recently constructed bridge decks exhibit transverse cracking at regular intervals. The cracks are noticed very soon after construction of the deck (at the project final). The cracks are not large cracks but they do continue down into the fascia of the bridge in many cases. Concrete will crack, but the location of these cracks in a high salt area and observed so soon after construction gets the corrosion process off to a head start. This project proposes to quantitatively measure the amount, location, and density of cracking in new bridges using projects constructed by the Bureau of Bridge Maintenance because these bridges tend to be similar in size (single-span, two-lane bridges with brush curb and bridge rail). One bridge will be built consistent with New Hampshire Department of Transportation (NHDOT) practice of recent years.
