SHEAR DISPLACEMENT RATE: 0.041nImIn <br /> 1. 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-6243 using a Brainard-Kallman LG-112 direct shear machine <br /> with an effective area of 12"x 12" 300 x300 mm). <br /> EST ORIENTATION: 4 NORMAL STRESS <br /> TOP BOX SUBGRADE SOIL GCL <br /> GEOMEMBRANE <br /> IF-BOTTOM BOX W/RIDGID SUBSTRATE GEOCOMPOSITE <br /> 'PECIAL TEST NOTES: <br /> 1. Each specimen of Geomembrane and Geocomposite was cut to 14"x 17". <br /> 2. The GCL specimens were cut to 14"x 14". <br /> 3. All Geosynthetic and GCL specimens were free floated between the upper and lower boxes. <br /> 4. All test points were hydrated for 24 hours at 100 psf. <br /> 5. All test points were consolidated for 2 hours at the specified normal stress,then sheared. <br /> 6. Shearing occurred at the interface of the smooth side of the Geomembrane and the non-textile side of the Geocomposite on all three points. <br /> 7. No noticable shearing occurred between the other interfaces on the three test points. <br /> o stretching,abrasion,or tearing was observed on any of the Geosynthetic specimens. <br /> I <br /> y-piing the data and result represented on this page,Client agrees to limit the liability of Vector Engineering,Inc,don client and all other parties for claims arising out of use of this date to <br /> ,a cast for the respective tests represented hereon,and Client agrees to indemnity and hold harmless Vector loom end against all liability in excess of the aforementioned limit. <br /> report Date: Entered By: Reviewed By:tx Lab Log: <br /> 07/26/99 JMR <br /> Page 2 of 2 161 D <br />
