Abstract:
This paper describes a method of measuring the thickness of pavement concrete and other concrete structural members. A particular feature of this method involves the combined usage of the ultra-sonic pulse and resonance methods to compute the thickness of concrete by measuring the sonic velocity and resonance frequency of concrete.
