GYRATORY COMPACTION OF SOIL; CRUSHED LIMESTONE, DATA REPORT

TESTS WERE PERFORMED TO DETERMINE THE EFFECT OF THE GYRATORY COMPACTOR'S THREE VARIABLES (ANGLE OF GYRATION, VERTICAL PRESSURE, AND NUMBER OF REVOLUTIONS) ON THE COMPACTION CHARACTERISTICS OF CRUSHED LIMESTONE. OTHER INFORMATION OBTAINED DURING THE TEST PROGRAM INCLUDED UPPER ROLLER PRESSURES (AN INDICATION OF SHEAR STRENGTH), SAMPLE REBOUND AFTER GYRATION, CALIFORNIA BEARING RATIOS INDICATING COMPARATIVE SOIL STRENGTH, REPRODUCIBILITY OF GYRATORY COMPACTION RESULTS, AND DEGRADATION OF AGGREGATE DURING GYRATORY COMPACTION. THE CRUSHED LIMESTONE WAS ALSO COMPACTED BY THE IMPACT COMPACTION METHOD FOR COMPARISON WITH THE GYRATORY COMPACTION RESULTS. AN EXAMINATION OF THE GYRATORY DATA INDICATED THAT INCREASING VERTICAL PRESSURE PRODUCED GREATER INCREASES IN DENSITY THAN INCREASING EITHER OF THE OTHER TWO VARIABLES, I.E. ANGLE OF GYRATION OR NUMBER OF REVOLUTIONS. WHEN THE VERTICAL PRESSURE WAS RELEASED FROM THE SAMPLE, ONLY A SMALL REBOUND WAS OBSERVED. TESTS OF THE AGGREGATE BEFORE AND AFTER GYRATORY COMPACTION SHOWED THAT A MINIMUM OF AGGREGATE DEGRADATIONS OCCURRED. THESE DATA ARE TO BE USED AS A PART OF A LATER ANALYSIS EXPLORING THE USE OF THE GYRATORY COMPACTOR IN THE DESIGN OF PAVEMENT STRUCTURES FOR PRESENT AND FUTURE TRAFFIC. /AUTHOR/
