EFFECTS OF MOULDING WATER CONTENT AND COMPACTION METHOD ON DEFORMATON AND STRENGHT CHARACTERISTICS OF COMPACTED SOIL

Abstract

 In this paper, the effects of moulding water content and compaction method on strength and deformation properties were evaluated by means of consolidated undrained triaxial compression test and bender element test on a silty sand. The test results showed that the specimens compacted at water content being slightly dry side of the optimum water content exhibited the lowest compressibility and the highest peak deviator stress. Effects of compaction method were manifested in that the peak deviator stress of a statically compacted specimen was hi gher than the dynamically compacted specimen. These test results were interpreted by considering the soil structure of compacted soil by bender element test.
