SUGGESTED NUCLEAR DEPTH-GAGE CALIBRATION PROCEDURES

AN EXPERIMENTAL PROCEDURE FOR CALIBRATION OF NUCLEAR DEPTH MOISTURE AND DENSITY GAGES IS DESCRIBED. CALIBRATION OF THE GAGES WAS ACCOMPLISHED UTILIZING LABORATORY STANDARDS CONSTRUCTED OF NATIVE OKLAHOMA SOILS. THE SOIL STANDARDS WERE COMPACTED TO A KNOWN DENSITY AND MOISTURE CONTENT. ONE SAND AND TWO COHESIVE SOILS WERE EMPLOYED. THE CALIBRATION CURVES FOR THE GAGES INDICATED THAT SOIL TYPE INFLUENCES INSTRUMENT RESPONSE. EACH SOIL HAD A SEPARATE AND UNIQUE CALIBRATION CURVE FOR MOISTURE CONTENT AND FOR DENSITY. THE USE OF DUAL-PURPOSE STANDARDS, TO CALIBRATE BOTH MOISTURE AND DENSITY GAGES, WAS PROVEN DESIRABLE. SPECIFIC CALIBRATION CURVES ARE RECOMMENDED FOR PROJECT USE. /AUTHOR/
