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, <5psl (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 Bralnard-Kiliman LG -112 direct shear machine <br />with an effective area of 12" x 12" (300 x300 mm). <br />TEST ORIENTA770N. NORMAL STRESS <br />GEOCOMPOSITE <br />TOP BOX WITH BOARD SPACERS GEOMEMBRANE <br />GCL <br />BOTTOM BOX W/ RIGID SUBSTRATE Asperity Height: 0.024 In. <br />SPECIAL TEST NOTES: <br />1. Each specimen of GCL, (burnish down) was cut and stapled to a rasp board in the lower shear box. <br />2. The HDPE, textured side on the GCL, smooth side up towards geocomposite, is free floating.. <br />3. Geocomposite sample were clample to the upper box, net towards the smooth HDPE. <br />4. The GCL/HDPE/Geocomposite were hydrated for 20 bus. under a 125 psf normal stress then loaded to the Normal stress for 24 hrs <br />5. Shearing occurred at the interface of the geocomposite and geomembrane smooth surface. <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 />- - -- -- •+ --, ••ro.� - ,,.> em u urw aaormawn are propnotaryand ran not be release0 wrYhOfit auMWtzatan ofVeclw E <br />9Y acceplkp roe data arMrest4 represetxed on this page.
