The Soniscope, an instrument which measures group velocities through as much as 50 ft of concrete, was used for the field testing of 13 bridges, one navigation lock, 14 dams and five highway pavements in 12 states. Repeated tests permitted study of changes in the condition of the concrete and of the structure. The value of the results increses with knowledge of the materials, mix design, method of placement and other characteristics of the structure being tested.
