EVALUATION OF DIRECT TRANSMISSION-TYPE NUCLEAR DENSITY GAGE FOR MEASURING IN-PLACE DENSITIES OF SOILS
THE DIRECT TRANSMISSION-TYPE NUCLEAR DENSITY GAGE HAS PROVED TO BE MORE ACCURATE AND FASTER THAN CONVENTIONAL METHODS. THE USE OF THE DIRECT TRANSMISSION PRINCIPLE SEEMS TO ELIMINATE THE NECESSITY FOR SEVERAL CALIBRATION CURVES. DENSITY TESTS CONDUCTED BY RESEARCH PERSONNEL ARE USUALLY MADE IN AREAS WHERE THE CONTRACTOR IS HAVING DIFFICULTY OBTAINING SPECIFIED DENSITY. THE NUCLEAR EQUIPMENT WITH ITS INHERENT SPEED HAS PROVIDED A MEANS WHEREBY THE ONCE TIME- CONSUMING TASK OF REPEATED DENSITY TESTS IS CONSIDERABLY REDUCED. THE EQUIPMENT IS ALSO USEFUL FOR SETTING UP COMPACTION EQUIPMENT SCHEDULES AND PROCEDURE. THE AMOUNT OF COVERAGE REQUIRED BY A GIVEN TYPE OF COMPACTION EQUIPMENT TO OBTAIN SPECIFIED DENSITY FOR AN ENTIRE JOB CAN BE DETERMINED QUICKLY FROM ONE TEST SECTION PROVIDED EXTENSIVE MOISTURE OR MATERIAL CHANGES ARE NOT ENCOUNTERED. /AUTHOR/
