Greater than 75% silt (1/256 to 1/16 mm) and clay (<1/256 mm), not bedded, well-sorted, grains too fine to judge roundness using hand lens. shale. WebA classification scheme for the shales and sandstones is proposed coupled with suggested allowable values for end bearing pressure and socket shear stress. These recommended pressures and shear stresses are based on limiting displacements to 1% of the socket or footing diameter.
