The "gap" between shear boxes was set at 80 mil (2.0 mm) <br />2. The test specimens were flooded during testing unless otherwise noted. <br />3. High Normal Stresses, >5psi (35 kPa) was applied using air pressure. <br />4. Low Normal Stresses, <5psi (35 kPa) was applied using dead weights. <br />5. The tests were terminated after 3.0"(75 mm) of displacement unless otherwise noted. <br />6. Tests were performed in general accordance with ASTM procedure D-5321 using a Brainard-Killman LG -112 direct shear machine <br />with an effective area of 12" x 12" (300 x300 mm). <br />TEST ORIENTATION: 8 NORMAL STRESS <br />TOP BOX WITH BOARD SPACERS GEOTEXTILE <br />222 211 22222211201-2112. <br />BOTTODM BOX W1 RIGID SUBSTRATE �- GEOMEMBRANE <br />Asperity Height: 0.021 in. <br />SPECIAL TEST NOTES: <br />1. Each specimen of geomembrane was cut to 14" x 20" and clamped to the lower shear box. <br />2. Each specimen of geotextile was cut to 14" x 16" and clamped to the upper shear box. <br />3. Each test interface was sprayed with water then consolidated for 2 hrs at the specified normal stress, then sheared. <br />4. The test was performed in a "wet" or "flooded" condition. <br />5. Shearing occurred at the interface of the textile and geomembrane specimens. <br />6. The Friction Angle and Adhesion (or Cohesion) results given here are based on a mathematically determined best fit line. <br />7.
