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 5321 using a Brainard-Kiliman LGA 12 direct shear machine <br /> with an effective area of 12"x 12"(300 x300 mm). <br /> TEST ORIENTATION: JJ NORMAL STRESS <br /> TOP BOX WITH BOARD SPACERS GEOMEMBRANE <br /> -- - - - --- GEOCOMPOSITE <br /> FE- BOTTOM BOX W/RIGID SUBSTRATE Asperity Height: .033 in. <br /> SPECIAL TEST NOTES: <br /> 1. Each specimen of geomembrane was cut to 14"x 16"and clamped to the upper shear box. <br /> 2. Each specimen of geocomposite was cut to 14"x 20"and clamped to the lower shear box. <br /> ' 3. Each test specimen was consolidated for 1/2 hour 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 geocomposite and geomembrane specimens. <br /> 6. Further interpretation should be conducted by a qualified professional experienced in geosynthetic and geotechnical engineering. <br /> This testing is based upon accepted industry practice as well as the test method listed. These results apply only to the samples <br /> supplied and tested for the above referenced job. <br /> LLatzxcelwtgedsICientINarreI2o12A1ro1349� Print Date: Entered By.
