MINIMIZING NUCLEAR SOIL DENSITY AND MOISTURE CONTENT GAGE ERRORS

THE SOURCES OF ERROR IN THE NUCLEAR SOIL DENSITY GAGES ARE IDENTIFIED AS SENSITIVITY TO VARIATIONS IN SAMPLE COMPOSITION, POOR CALIBRATION TECHNIQUE, AND SENSITIVITY TO SURFACE HETEROGENEITIES. THE ERRORS ASSOCIATED WITH THE NUCLEAR MOISTURE CONTENT GAGES ARE IDENTIFIED AS SENSITIVITY TO SOIL DENSITY, AND POOR CALIBRATION TECHNIQUE. SEVERAL APPROACHES ARE DESCRIBED AND EVALUATED FOR MINIMIZING THESE SOURCES OF ERROR, INCLUDING MATHEMATICAL ANALYSES OF THE NUCLEAR GAGING PRINCIPLES, THE CALIBRATION MODEL METHOD, AND THE DUAL-GAGE PRINCIPLE FOR NUCLEAR DENSITY GAGES. /AUTHOR/
