WebApr 28, 2024 · 60 Altmetric. Metrics. Soil–structure interfaces typically exhibit a shear behavior that is independent of the direction of relative displacement due to symmetry in the solid material's surface profile. This experimental study investigates the interface shear behavior of surfaces with asymmetric profiles inspired by the scales of snake skin. WebA definition as to whether soil groups form a continuum between CLAY and SILT or whether they are subsets of them. Contour encloses 4 or more data points per 10% triangle. certain A group index value equal to zero indicates a good subgrade material, whereas group index value equal to or greater than 20 indicates a very poor subgrade material.
