THE DEVELOPMENT OF ULTRASONIC NONDESTRUCTIVE TESTING INSTRUMENTATION TO MEASURE PAVEMENT THICKNESS

ULTRASONIC INSTRUMENTATION IS DEVELOPED TO MEASURE THE THICKNESS OF CONCRETE PAVEMENTS. AN INSTRUMENT HAS BEEN DEVELOPED WHICH IS CAPABLE OF MEASURING THE THICKNESS OF HARDENED CONCRETE TEST BLOCKS TO WITHIN 2% UNDER LABORATORY CONDITIONS. PRELIMINARY FIELD TEST DATA SUGGEST THAT THIS ACCURACY CAN ALSO BE OBTAINED ON CONCRETE PAVEMENTS. A LABORATORY INVESTIGATION INDICATED THIS INSTRUMENT COULD NOT MEASURE THE THICKNESS OF PLASTIC CONCRETE IMMEDIATELY AFTER PLACING. AN ANALYSIS OF THE RESULTS INDICATED THAT IT WAS UNLIKELY THAT ANY ACOUSTIC TECHNIQUE COULD PERFORM THIS FUNCTION. ALTHOUGH THIS EQUIPMENT AT THIS STAGE INDICATES IT MAY NOT BE AS ACCURATE AS THE CONVENTIONAL CORING PROCEDURE, IT IS BELIEVED IT HAS GREAT POTENTIAL VALUE WITH ITS ABILITY TO PERMIT SCRUTINY OF A LARGER PERCENTAGE OF THE TOTAL PAVEMENT AREA. /AUTHOR/
