Abstract:
THE BASIC PRINCIPLES OF SOIL COMPACTION ARE DISCUSSED AND THE FUNDAMENTAL REQUIREMENTS FOR A SATISFACTORY LABORATORY-COMPACTION TEST ARE SET FORTH. FIELD CURVES OBTAINED BY THE USE OF SHEEPSFOOT ROLLERS AND RUBBER-TIRED ROLLERS ARE COMPARED WITH LABORATORY CURVES OBTAINED BY STATIC LOADING, IMPACT LOADING (PROCTOR COMPACTION), AND "KNEADING STATIC COMPACTION." THE KNEADING STATIC COMPACTOR DEVELOPED AT NORTHWESTERN UNIVERSITY FOR SIMULATING MORE CLOSELY THE ACTION OF FIELD COMPACTING EQUIPMENT IS DESCRIBED IN DETAIL. DATA ARE PRESENTED TO SHOW THAT THE POSITION OF THE OPTIMUM CURVE WITH RESPECT TO THE ZERO AIR-VOIDS CURVE IS A FUNCTION OF THE TIME INCREMENT THAT THE FOOT PRESSURE IS MAINTAINED. /AUTHOR/
