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 LG-112 direct shear machine <br /> with an effective area of 12"x 12"(300 x300 mm). <br /> EST ORIENTATION: NORMAL STRESS <br /> TOP BOX WITH BOARD SPACERS GCL <br /> BOTTOM BOX W/RIDGID SUBSTRATE -�- GEOMEMBRANE <br /> PECIAL TEST NOTES: <br /> 1. Each specimen of Geomembrane and Geocomposite was cut to 14"x 17"and the GCL specimens were cut to 14"x 14" <br /> 2. The initial GCL moisture content was 10.3%. The final moisture contents ranged from 58 to 65%. <br /> 3. All Geosynthetic specimens were free floated between the upper and lower boxes. <br /> 4. Soil specimens were remolded into both upper and lower boxes. <br /> 5. The full test section was hydrated for 24 hours at 100psf in the shear box. <br /> 6. After hydration,points were consolidated for 2 hours at the specified normal stress,then sheared. <br /> 7. Shearing occurred at the interface of the sub-grade soil in the lower box and the Geocomposite on points 1 and 2. <br /> R. Shearing occurred at the interface of the sub-grade soil in the upper box and GCL for the first part of the test and <br /> winat the interface of the soil in the lower box and Gecomposite for the second part of the test for point 3. <br /> o observable displacement,stretching or abrasion occurred at the other interfaces for test pts. 1,2 R 3. <br /> the data and result reoresented on this oaoe.Client acrees to limit the liability or Vector Enaineenno.Inc.from client and all other oarves for claims ansino out or use of this data to <br /> >cost for the respective tests represented hereon,and Client agrees to indemnity and hold harmless Vector from and a ainsl all liability in excess of the aforementioned limit. <br /> eport Date: Entered By: Reviewed By Lab Log: <br /> 09/15/99 NCL Page 2 of 2 2 ZE <br />
