Abstract

This method of test is intended to determine the properties of stability for soils and soil mixtures at zero pore pressure conditions. These properties are the angle of internal friction and cohesion, and, for given pressure ranges, shear strength and modulus of deformation. Pore pressure values are obtained for the imposed load conditions. The equipment is suitable for testing standard remolded or undisturbed specimens, 3¼ in. in diameter by 9 in. long, small undisturbed specimens 1⅜ in. in diameter by 2¾ in. long, or any intermediate size specimens.
