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-Kiilman LG -112 direct shear machine <br />with an effective area of 12" x 12" (300 x300 mm). <br />TEST ORIENTATION: NORMAL STRESS U <br />TOP BOX WITH BOARD SPACERS GEOTEXTILE <br />GEOMEM BRANS <br />WM*BOTTOM BOX INI RIGID SUBSTRATE Asperity Height: 0.018 in. <br />SPECIAL TEST NOTES: <br />1. Each specimen of geomembrane was cut to 14" x 20" and clamped to the tower shear box. <br />2. The geotextile specimen was clamped to the top shear box. <br />3. Each test specimen was consolidated for 1 hour at the specified normal stress, then sheared. <br />4. The test was performed in a "wet" or "flooded" condition. <br />5. Shearing occurred at the interface of the geotextile and geomembrane specimens. <br />6. The Friction Angle and Adhesion (or Cohesion) results given here are based on a mathematically determined best fit line. <br />7. Further interpretation should be conducted by a qualified professional experienced in geosynthetic and geotechnical engineering. <br />These resrdrs applyonty to the above listed samples Jmaterlals. the data and rdermatxm are proprielary and can" oe rereasea »nra7w aumormarxm w pccrw —Y --w 1— <br />By accepling the data and resu4 rapresenled on this page. cliem agrees to &a pre Labuy or Vector Engkwering. me Iran dent and all oltw parties kr daxas afis✓rg out of use of this <br />date to The cost Ia the respective lest(s) represenled herd. and pleat agrees to indernnay and 1KKd harmless Veda from and against all k"y in excess or rhe a(aemerrlloaed limd <br />-Labexcel t Projects 12002 1021605 1 1492L-LSDS-rp E"lered @v 144 AW Dare 0"4105 Rep ray 1111 <br />Lab Log: <br />DCN: LSOSap (tcv.. 03101104) <br />Page 2 of 2 <br />ia N. <br />0 <br />
