Abstract

Bender element tests were performed on unsaturated kaolin samples prepared by four different types of anisotropic compaction and one type of isotropic compaction, together with a corresponding test on a saturated anisotropic reconstituted kaolin sample. Two pairs of bender elements were used in each test, both employing horizontal wave transmission but one with horizontal wave polarization and the other with vertical wave polarization. The results indicate that Modified Proctor dynamic compaction and an even heavier form of dynamic compaction produced samples with Ghh greater than Ghv, whereas two types of lighter anisotropic static compaction produced samples with Ghh less than Ghv. Given what is already known about anisotropy of large strain plastic behaviour of compacted soils, the results suggest that anisotropy of small strain elastic be-haviour and anisotropy of large strain plastic behaviour depend upon different aspects of soil fabric.
