PAVEMENT THICKNESS MEASUREMENT USING ULTRASONIC TECHNIQUES

THE DEVELOPMENT AND FIELD EVALUATION OF AN ULTRASONIC PULSE-ECHO TYPE OF INSTRUMENT FOR MEASURING THE THICKNESS OF PORTLAND CEMENT CONCRETE PAVEMENTS ARE DESCRIBED. THE RESULTS SHOW THAT THE SYSTEM WAS ACCURATE TO WITHIN PLUS OR MINUS 3 PERCENT AT 78 OF THE 100 TEST LOCATIONS. RESULTS WERE CHECKED BY CORE MEASUREMENTS MADE BY THE OHIO DEPARTMENT OF HIGHWAYS. THE THICKNESS GAGE WAS ALSO EVALUATED ON PLASTIC CONCRETE. THE RESULTS SHOW THAT THIS INSTRUMENT IS NOT CAPABLE OF MEASURING THE THICKNESS OF PLASTIC CONCRETE AND ALSO SUGGEST THAT IT IS UNLIKELY THAT ANY METHOD USING ULTRASOUND COULD PERFORM THIS FUNCTION WITH THE DESIRED DEGREE OF ACCURACY. LABORATORY EXPERIMENTS ON BLOCKS OF BITUMINOUS CONCRETE INDICATE THAT THIS INSTRUMENT CAN BE USED TO MEASURE THE THICKNESS OF THIS MATERIAL AT MODERATE TEMPERATURES. /AUTHOR/
