Abstract

The effects of inherent anisotropy produced by compaction on the strength and deformation characteristics of unsaturated specimens of compacted cement-mixed gravelly soil were evaluated by performing a series of consolidated drained (CD) triaxial compression (TC) test. Specimens were prepared by compacting in the direction of compression in the TC tests and its perpendicular direction. It is shown that these two types of specimen exhibited nearly the same stiffness at small strain and viscous property. The effects of compaction in the two orthogonal directions increase with an increase in the strain with noticeable effects on the peak strength and more in the post-peak regime. The effects are however generally small, much less significant than those observed with air-pluviated unbound sand. The effects of total compacted dry density of solid and curing period on the stress-strain behaviour were found nearly the same between the specimens compacted in the two orthogonal directions.
