A continuous, rough, clean joint surface completely cuts through the block (gabbro) shown in the Figure below. The joint surface's JRC is 12-14 (measured @ 10cm scale for wall-to-wall contact, no fill). The shear strength of the joint surface (peak conditions, wall-to-wall contact, no fill) is given by: = 0.025MPa Tan(42), for [0.10, 1.5MPa]
