THE TECHNICAL ASPECTS OF COMPACTION IN EARTHMOVING AND ROAD CONSTRUCTION

THIS PAPER DESCIBES FIELD TESTS CARRIED OUT WITH FOUR TYPES OF ROLLER: STEEL WHEEL ROLLERS WITH A STATIC EFFECT, VIBRATORY ROLLERS WITH A DYNAMIC EFFECT, RUBBER-TIRED ROLLERS WITH STATIC AND KNEADING EFFECTS, AND VIBRATORY SHEEPSFOOT ROLLERS WITH DYNAMIC AND KNEADING EFFECTS. RESULTS OF THESE TESTS INDICATED THAT THESE TESTS INDICATED THAT THE EXPRESSION "LINEAR ROLLER PRESSURE" IS A REPRESENTATIVE QUANTITY INDICATIVE OF THE COMPACTIVE ABILITY OF STATIC WHEEL ROLLERS. THE COMPACTION ABILITY OF VIBRATORY ROLLERS DEPENDS ON THE TYPE OF VIBRATOR AND THE TYPE OF SOIL. THE TERM EQUIVALENT COMPACTIVE FORCE" SHOULD NOT BE USED TO EXPRESS COMPACTIVE ABILITY OF VIBRATORY ROLLERS UNLESS THE MATERIAL IS ALSO SPECIFIED. THE COMPACTIVE EFFECT OF RUBBER-TIRED ROLLERS DEPENDS UPON WHEEL LOAD AND THE SIZE OF THE CONTACT AREA. FOR THE COMPACTION OF BITUMINOUS LAYERS VIBRATORY AND RUBBER-TYRED ROLLERS GIVEN THE BEST RESULTS. /TRRL/
