RELATIVE COMPACTION STUDY

THE PRINCIPLES INVOLVED IN DETERMINING THE PERCENT OF RELATIVE COMPACTION WHEN USING A STATISTICAL AREA CONCEPT METHOD WERE INVESTIGATED. DATA WERE COLLECTED FROM FIVE PROJECTS. IT WAS CONCLUDED THAT THE FIELD USE OF THE WET METHOD AND COMPOSITE TEST MAXIMUM DENSITY IS GOOD. THE USE OF A STATISTICAL RANGE OF VALUES APPEARS FEASIBLE FOR UNIFORM MATERIALS. THE CORRELATION OF STANDARD LABORATORY AND FIELD METHODS OF CALIBRATION IS GENERALLY GOOD FOR DENSITY BUT NOT FOR MOISTURE. THE DIFFERENCE IN TEST VALUES DUE TO TESTING AT DIFFERENT DEPTHS IS POOR. DENSITY AND MOISTURE DETERMINATIONS FROM ONE ONE-MINUTE NUCLEAR GAGE READING ARE COMPARABLE TO THE DETERMINATION MADE FROM THE AVERAGE OF TWO ONE-MINUTE READINGS. /AUTHOR/
