The "gap" between shear boxes was set at 80 mil (2.0 mm) The test specimens were flooded during testing unless otherwise noted. High Normal Stress (>5psi) was applied using air pressure. Low Normal Stress (<5psi) was applied using dead weights. The tests were terminated after 3.0" of displacement unless otherwise noted. Tests were performed in general accordance with ASTM procedure D-5321-92 Method B using a Brainard-tGllman LG -112 direct shear machine with an effective area of 12"x 12".

The soil was remolded in the upper box to approximately 90% of its maximum dry density, and 2 percent over optimum moisture content. The GCL specimens were hydrated for 24 hrs under 100 psf, loaded into the test specimen for 2 hours under normal stress and then sheared. The initial water content of the GCL was 24.8% and final water contents were: pl.1: 104.19%, pt.2: 99.56%i pt.3: 82.58%.
