Water drops can diagnose bridge health

Researchers at Brigham Young University in Utah report the method, called impact-echo testing, can diagnose the health of a bridge’s road deck based on the acoustic footprint produced by falling water…
 “We would love to be able to drive over a bridge at 25 or 30 mph, spray it with water while we’re driving and be able to detect all the structural flaws on the bridge,” Mazzeo said. “We think there is a huge opportunity, but we need to keep improving on the physics.”
