LABORATORY AND FIELD EVALUATION OF NUCLEAR SURFACE GAGES FOR DETERMINING SOIL MOISTURE AND DENSITY
A LABORATORY EVALUATION OF THE NUCLEAR SURFACE GAGES FOR DETERMINING SOIL MOISTURE AND DENSITY WAS CONDUCTED USING EIGHT SOILS FROM VARIOUS AREAS OF CALIFORNIA. A CALIBRATION CURVE WAS DEVELOPED FOR EACH SOIL AND ALL CALIBRATION CURVES WERE COMPARED. THE VOLUME OF SOIL BEING MEASURED WAS DETERMINED. THE REPRODUCIBILITY AND OTHER CHARACTERISTICS OF THE NUCLEAR GAGES WERE STUDIED. THE NUCLEAR GAGES WERE USED ON TEN PROJECTS UNDER CONSTRUCTION AND THE NUCLEAR READINGS WERE COMPARED TO CONVENTIONAL TESTS. THE RESULTS OF THIS EVALUATION PROGRAM INDICATED THAT INDIVIDUAL CALIBRATION CURVES WOULD BE REQUIRED FOR THE VARIOUS SOILS ENCOUNTERED. /AUTHOR/
