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 ASTM D-5321 using a Brainard-Kiliman LG-112 direct shear machine <br /> with an effective area of 12"x 12"(300 x300 mm). <br /> TEST ORIENTATION: g NORMAL STRESS <br /> TOP SOX WITH BOARD SPACERS ,GEOCOMP®SITE <br /> GEOMEMBRANE <br /> BOTTOM BOX W/RIGID SUBSTRATE GCL <br /> SPECIAL TEST NOTES: <br /> 1. Each specimen of geocompoSite was cut to 14"X 16"and damped to the upper shear box,net down to smooth HDPE. Asperity Height=.025 <br /> 2. Each specimen of geomembrane was cut to 14"x 20"and floated between the composite and GCL,textured side toward the GCL <br /> 3. Each specimen of GCL was cut to 14"x 20"and mounted to rasp boards placed In the tower box,burnished side to HOPE. <br /> 4. Each specimen was hydrated under a 125 psf normal stress approximately 24 hours then consolidated <br /> 5. After hydration each specimen was consolidated under the normal stress approximately 24 hours then sheared. <br /> 6_ The test was performed in a"wet"or"flooded"condition. <br /> 7. Shearing occurred at the interface of the geocomposite net and smooth side of the geomembrane specimens. <br /> The Friction Angle and Adhesion(or Cohesion)results given here are based on a mathematically determined best fit line. <br /> Further interpretation should be conducted by a qualified professional experienced in geosynthetic and geotechnical engineering. <br /> These results eppry only to the abo /lsted damplos/materiels. me dots end information are propnotory Sad Can nor De released without author ation of vinectw EngfneerUi9 C. <br /> ve <br /> By accepting the dale and result represented on this page,Client agrees to SM the llob4t'y of Vector Engmeenng,inc.from went and alt other parties far Gelms orking out cruse orlhis <br /> date to the cost rot the respecWo tost(s)represented hereon.antl CNent agrees to tedemndy and told harmless Vector rrom and agakst of&WAY dl excess of the atwomenwned Limn. <br /> L:1la3bexcef 1 Prquets 11902102160517432-1-tsds Entered By.' xRC PHNDate: 08/01/02 Rev.By- Lab Log: <br /> 743Z-1 <br /> DCN:LSDS-rp(rev.6-27-00) <br /> Page 2 of 2 <br />
