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: 8NORMAL STRESS <br /> TOP BOX WITH BOARD SPACERS GEOTEXTILE <br /> E-' BOTTOM BOX W/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_ Further interpretation should be conducted by a qualified professional experienced in geosynthetic and geotechnical engineering. <br /> These results apply only to the above listed samples i materials.
