A RAPID METHOD FOR DETERMINING THE IN-PLACE DENSITY OF A PAVEMENT BASE COURSE BY A DROP-HAMMER PENETROMETER

AS CONSTRUCTION TECHNIQUES IMPROVE TO KEEP PACE WITH THE DEMANDS FOR BETTER HIGHWAY SYSTEMS, QUALITY CONTROL METHODS HAVE LAGGED BEHIND. AS CONSTRUCTION RATES INCREASE, MORE TESTS MUST BE MADE PER UNIT OF TIME IN ORDER TO KEEP ABREAST OF CONSTRUCTION SCHEDULES. SINCE THE DENSITY OF THE BASE COURSE IS FUNDAMENTAL TO THE SUCCESS AND STRENGTH OF ANY HIGHWAY, IT MUST BE TESTED FREQUENTLY TO INSURE ITS QUALITY. PRESENT TESTS ARE SLOW. THIS IS A REPORT ON A PROJECT TO DEVELOP A RAPID IN-PLACE TEST. THE DESIGN CRITERIA WERE' /1/ A RAPID METHOD TAKING LESS THAN 20 MINUTES TO PERFORM, /2/ ACCURACY TO WITHIN 3 PER CENT, PLUS OR MINUS, /3/ SIMPLICITY , /4/ ECONOMY, AND /5/ USING LESS THAN TWO MEN TO PERFORM. A PENETROMETER WAS DESIGNED, DEVELOPED AND TESTED WHICH MET ALL THE CRITERIA BUT ACCURACY. IT IS RECOMMENDED THAT FIELD CALIBRATION OF THE DEVICE, RATHER THAN LABORATORY CALIBRATION WOULD IMPROVE THE ACCURACY. STATISTICAL ANALYSIS OF THE RESULTS SUGGESTED A CORRELATION BETWEEN DENSITY AND PENETRATION. /AUTHOR/
