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-Killman LG-112 direct shear machine <br /> with an effective area of 12"x 12"(300 x300 mm). <br /> TEST ORIENTATION: 4 NORMAL STRESS <br /> TOP BOX WITH BOARD SPACERS CLAY <br /> GEOMEMBRANE <br /> BOTTOM Box cur RIGID SUBSTRATE DRAINAGE LAYER <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. The test clay was placed In the upper shear box at a app.dry density of 104 pcf and a water content of 18%. <br /> 3. Each test specimen was consolidated for 24 hours 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 clay 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 geosynthette and geotechnical engineering. <br /> Lose msu8s appy only to the aoove listed s01"p/es/materials.
