Mar 14, 2008 · In theory, every soil will have zero residual cohesion if sheared at a slow enough rate. We are running one cycle on the direct shear machine, unless it is on a sample of landslide plane or a clay bed in bedrock to model adverse bedding, then it is three cycles. Our competitors should be reporting residual values as directed by local guidelines.
