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, >$psi (35 kPa) was applied using air pressure. <br />4. Low Normal Stresses, <5psi (35 kPa) was applied using dead watghts. <br />5. The tests were terminated after 3.0175 mm) of displacement unless otherwise noted. <br />6. Tests were performed in general accordance with ASTM procedure ASTM D-5321 using a Brainard-Klllman LG -112 direct shear machine <br />with an effective area of 12" x 12" (300 x300 mm). <br />TEST OPJENTATION.

Each specimen of geocomposite was cut to 14"x 16" and damped to the upper shear box, net down to smooth HDPE. Asperity Height =.025 <br />2. Each specimen of geomembrane was cut to 14' x 20" and floated between the composite and GCL, textured side toward the GCL <br />3. Each specimen of GCL was cut to 14" x 20" and mounted to rasp boards placed In the tower box, burnlshed side to HOPE. <br />4. Each specimen was hydrated under a 125 pef normal stress approximately 24 hours then consolidated <br />6. After hydration each specimen was consolidated under the normal stress approximately 24 hours then sheared. <br />6. The test was performed in a "wet" or "flooded" condition. <br />7. Shearing occurred at the interface of the geoeomposite net and smooth side of the geomembrane specimens. <br />8. The Friction Angle and Adhesion (o Cohesion) results given here are based on a mathematically determined best fit line. <br />`9. Further interpretation should be conducted by a qualified orofesslonal experienced in geosynthetic and geotechnical engineering. <br />Theee roxilq eppty onry Iv Ihs oGovs 1plso so,"plos /msferle/s.
