Staged compression-immersion direct shear test on compacted crushed mudstone
This paper introduces a staged compression-immersion-direct shear test carried out in order to deal with compressive settlement phenomena of compacted crushed mudstone during staged filling and due to immersion from the viewpoints of not only deformation but also shear strength deterioration. The test apparatus and procedure are described, and as an example, compacted crushed Kobe mudstone samples are tested. It is shown that as expected, the crushed Kobe mudstone samples compacted with 95% degree of compaction exhibit larger compressive settlement than those compacted with 100% degree of compaction during staged loading, and that only the former samples show additional compression due to immersion. Shear strength decreases due to immersion being accompanied with volume decrease, and the shear strength decrease and volume change are larger in the samples compacted with 95% degree of compaction. It is also indicative that the shear strength of the aggregate itself has a significant influence on the shear strength of its compacted samples.
