The Development of Ultrasonic Nondestructive Testing Instrumentation to Measure Pavement Thickness
The objective was the development of ultrasonic instrumentation to measure the thickness of concrete pavements. An instrument was developed which can measure the thickness of portland cement concrete to within plus or minus 2% under laboratory conditions. Preliminary field test data suggest that this instrument is capable of the same accuracy on highway pavements. A laboratory investigation was also conducted to evaluate the capability of this instrument to measure the thickness of plastic concrete pavements. If this instrument could measure the thickness of concrete immediately after pour, it could be used to monitor, and control, the laying of pavements by a slip-form paver. The results of this study, however, showed that this instrument could not measure concrete thickness immediately after pour. An analysis of the results also indicated that it was unlikely that any acoustic technique could perform this function. (Author)
