EVALUATION OF RAPID FIELD METHODS FOR MEASURING COMPACTED SOIL PROPERTIES

RAPID METHODS OF MEASURING PROPERTIES OF COMPACTED SOILS FOR PURPOSES OF CONSTRUCTION CONTROL WERE STUDIED. A NUMBER OF TECHNIQUES FOR DETERMINING DENSITY, STRENGTH AND STIFF- NESS CHARACTERISTICS OF SOILS WERE EVALUATED IN TESTS PROVIDING A RANGE OF SOIL TYPES AND A VARIETY OF COMPACTION METHODS. COMMERCIALLY AVAILABLE DEVICES WERE /1/ A PORTABLE BACK-SCATTER NUCLEAR MOISTURE/DENSITY INSTRUMENT, /2/ A NUCLEAR ROAD LOGGER FOR MEASURING MOISTURE AND DENSITY, AND /3/ A SEISMOGRAPH. IN ADDITION, APPARATUS WAS DESIGNED AND CONSTRUCTED FOR RAPIDLY MEASURING PENETRATION RESISTANCE USING A CONE PENETROMETER, STIFFNESS USING A 6-IN. DIAMETER BEARING PLATE, AND CBR. FOR COMPARISON CONVENTIONAL SAND CONE AND MOISTURE CONTENT MEASUREMENTS WERE OBTAINED. THE RESULTS SHOW THE SUITABILITY OF THE DEVICES FOR DETECTING CHANGES IN COMPACTION WITH COMPACTIVE EFFORT, THE CORRELATION BETWEEN THE DIFFERENT METHODS AND THE VARIABILITY OF THE OBSERVED PROPERTIES. /AUTHOR/
