DETERMINING CONCRETE HIGHWAY PAVEMENT THICKNESS USING WAVE SPEED MEASUREMENTS AND THE IMPACT-ECHO METHOD

This paper describes the use of the impact-echo method in conjunction with a wave-speed measurement technique which can nondestructively and accurately determine the thickness of new concrete pavements. Portable instrumentation (computer, data-acquisition hardware, transducers, and impactor) that can be used to perform both wave speed and impact-echo measurements accurately and reliably has been asembled. Results of preliminary field studies carried out on a Strategic Highway Research Program (SHRP) Test Section in Arizona are reported, including results obtained from pavements having different thicknesses, different strengths, and placed on different types of subgrades.
