SOIL COMPACTION EVALUATION WITH STRAIN MEASUREMENTS

THE PURPOSE WAS TO INVESTIGATE THE USE OF A NEW SOIL STRAIN MEASURING SYSTEM FOR OBSERVING COMPACTION OF EARTH MATERIALS IN THE FIELD. THE SENSORS CONSISTED OF DISK-SHAPED COILS EMBEDDED IN THE MATERIAL WITH THE DISTANCE BETWEEN ADJACENT PAIR DETERMINED BY INDUCTANCE COUPLING. A SERIES OF EXPERIMENTS WERE CONDUCTED DURING CONSTRUCTION OF PORTIONS OF AN INTERSTATE HIGHWAY AND THE SOUTHERN TIER EXPRESSWAY IN NEW YORK STATE AND IN A A SPECIAL TEST SECTION AT THE WATERWAYS EXPERIMENT STATION IN VICKSBURG, MISSISSIPPI. THE RESULTS ESTABLISHED THE ADVANTAGES AND LIMITATIONS OF THE METHOD, AND TECHNIQUES FOR SENSOR INSTALLATION WERE DEVELOPED. NEW INFORMATION ON COMPACTION WAS OBTAINED IN THE PROCESS OF STUDYING THE INSTRUMENTATION. /AUTHOR/
