FILL COMPACTION BY VIBRATING ROLLERS. THEORY AND PRACTICE

THE ARTICLE EXAMINES THE DIFFERENCE BETWEEN TWO MAIN CATEGORIES OF VIBRATING ROLLERS USED FOR COMPACTING FILL. THE TWO CATEGORIES ARE 1) THOSE WHICH EMPLOY A ROTATING OUT- OF-BALANCE MASS TO CREATE VIBRATION AND PROVIDE UNRESTRAINED MOVEMENT IN ALL DIRECTIONS AND 2) THOSE WHICH HAVE TWO COUNTER-ROTATING MASSES WHICH ARE PHASED SO THAT ALL HORIZONTAL COMPONENTS OF VIBRATION ARE CANCELLED OUT AND MOTION IS ONLY IN THE VERTICAL DIRECTION. THE MAIN DIFFERENCE BETWEEN THE TWO TYPES IS THAT IN THE 1ST CATEGORY THE PARTICLES OF MATERIAL BELOW THE ROLL PRODUCE A POND EFFECT WHEREAS IN THE 2ND TYPE THEY PRODUCE A PYRAMID EFFECT. THE ARTICLE ALSO CONSIDERS THE ECONOMIC CHOICE OF ROLLERS FOR PARTICULAR CONTRACTS, THE MAIN CONSIDERATION BEING THE SIZE OF THE CONTRACT AND THE DAILY OUTPUT REQUIRED
