Nondestructive Concrete Tests Grand Coulee Spillway Bridge
Nondestructive sonic pulse velocity and impact hammer tests were conducted on the Grand Coulee Spillway bridge. Test results were correlated with tests on a small number of 6-in.-dia cores from noncritical areas, to evaluate the bridge concrete. Additional tests were performed on concrete in areas showing minor distress. The concrete in the bridge is in excellent condition, having a compressive strength of 8700 psi (612 kg/sq cm) in the deck and 7630 psi (536 kg/sq cm) in the vertical walls. Pulse velocities indicate that the arch concrete is high quality and that concrete in the deck is slightly lower in quality, probably because of minor deterioration of the surface caused by traffic.
