SHEAR DISPLACEMENT RATE: 0.041n/min <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,>5psl(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 /> ST ORIENTATION: NORMAL STRESS <br /> TOP BOX WITH CLAY <br /> BOTTOM BOX WITH PEA GRAVEL -�'- GEOMEMBRANE <br /> ECTAL TEST NOTES: <br /> 1. Each specimen of Geomembrane was cut to 14"x 17"and floated between the upper and lower box. <br /> 2. The clay was remolded in the upper box to the specified compaction requirements. <br /> 3. The 5/16"pea gravel was lightly tamped into place in the lower box. <br /> 4. All test points were consolidated for 2 hours at the specified normal stress,then sheared. <br /> 5. Shearing occurred at the interface between the clay and the textured side of the Geomembrane specimen at test points 2 and 3. <br /> 6. Shearing occurred at the interface between the pea gravel and the smooth side of the Geomembrane specimen at test point 1. <br /> 7. No stretching,abrasion,or tearing occurred on the Geomembrane specimens at the three test points. <br /> I , <br /> e data end result represented on this page,Cliept-grew to limit the liability of Nectar Engineering,Inc.from client and all other parties for claims arising out of use of this date to <br /> res active tests re resented hereon,end CfieAt.A rees to indemnity and hold harmless Vector from and against all liability in excess of the aforementioned limit. <br /> tort Date: Entered By Reviewed By:t,4t Lab Log: <br /> 06/28/99 AIR Page 2 of 2 120Q <br />
