A comprehensive experimental test program was performed on kaolinite clay with a wide range of confining pressures and different over-consolidation ratios (OCR). The test program began with an evaluation of radial drainage materials with respect to hydraulic conductivity, volumetric compliance, and vertical loading correction. A criterion was proposed to ensure sufficient flow capacity of the drainage material. Corrections for volumetric compliance and vertical load were considerable. The following program focused on different stress paths in the triaxial plane, including drained compression, undrained compression, drained extension, and undrained extension. Kaolinite clay was tested over a confining pressure range of 50 to 2900 kPa and its behavior was found to be similar to results from most prior studies at low pressures of less than 400 kPa. These findings include: the strength and stiffness increase with increasing confining pressure and OCR; the compressive volume change tendency decreases with OCR; unique failure envelopes; and a unique critical state line. Unusual behavior was found mainly in the following three areas: reverse anisotropic response during multi-step isotropic consolidation, a narrow dilatant region near failure for normally consolidated kaolinite clay in extension, and possible compressive volume change inside shearing bands.
