NUCLEAR TEST EQUIPMENT INVESTIGATION - ASPHALTIC CONCRETE DENSITY GAUGES

THE THREE PIECES OF EQUIPMENT INVOLVED WERE A NUCLEAR- CHICAGO MODEL 5846 DENSITY GAUGE, A LANE-WELLS ROAD LOGGER, AND A SEAMAN MODEL 75 MOISTURE/DENSITY GAUGE. IT IS CONCLUDED THAT NONE OF THESE UNITS WOULD BE SATISFACTORY FOR THE MEASUREMENT OF ABSOLUTE DENSITY, BUT THAT THEY MIGHT BE USED IN SOME MANNER TO MEASURE RELATIVE DENSITY. IT IS BELIEVED THAT THE MOST PRACTICAL USE WOULD BE TO COMPARE THE AVERAGE DENSITIES OF SECTIONS OF SURFACE WITH THE DENSITY OF A CONTROL SECTION. THE LENGTH OF TIME REQUIRED TO MAKE A MEANINGFUL DETERMINATION WITH THE TWO PORTABLE GAUGES, AND THE DEPTH OF PENETRATION OF THE ROAD-LOGGER ARE CONSIDERED SERIOUS DRAWBACKS. /FHWA/
