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 LGA 12 direct shear machine <br />with an effective area of 12" x 12" (300 x300 mm). <br />TEST ORIENTATION: NORMAL STRESS EOTEXTILE <br />i TOP BOX WITH BOARD SPACERS <br />GEOMEMBRANE <br />BOTTOM BOX W1 RIGID SUBSTRATE Asperity Height: 0.023 in. <br />SPECIAL TEST NOTES: <br />1. Each specimen of geomembrane and geotextile was cut to 14" x 20" and clamped to its respective position. <br />2. Each test specimen was consolidated for 2 hours at the specified normal stress, then sheared. <br />3. The test was performed in a "wet" or "flooded" condition. <br />4. Shearing occurred at the interface of the geotextile and geomembrane specimens. <br />5. The Friction Angle and Adhesion (or Cohesion) results given here are based on a mathematically determined best fit line. <br />6. Further interpretation should be conducted by a qualified professional experienced in geosynthetic and geotechnical engineering. <br />,ox rasuns appy omy ro me acove asreo samples r materws. the data and rttamatron are proprietary and can not be released wfthou( authorLation of Vector Engineering Inc. <br />By accepting the data and result represented an this page.
