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: 4 NORMAL STRESS <br /> TOP BOX WITH CLAY <br /> BOTTOM BOX WITH PEA GRAVELm IBM G E O M EM B RAN E <br /> DECIAL TEST NOTES: <br /> 1. Each specimen of Geomembrane was cut to 1,4!'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 /> accepMg the data end result represented on this page,Cliep4grees 10 limit the liability of Vector Engineering,Inc.from client and all other parties for claims arising out of use of this data to <br /> cost <br /> for the respective tests represented hereon,and Clie rees to indemnityand hold harmless Vector from and against all liabilityin excess of the aforementioned limit. <br /> sport Date: Entered By: Reviewed By: Lab Log <br /> 06/28/99 JMR Page 2 of 2 120Q <br />
