3.0 Test Configurations <br />The test was assembled by compacting the soil liner fill material at approximately 95% <br />standard proctor maximum density. The geomembrane sample was placed on top of this <br />surface. It was then followed by the low volume solution collection fill material to <br />complete the soil profile. The sample was then loaded in 50 pounds per square inch <br />(psi) per hour increments until the target pressure of 385 psi was reached. The full <br />load was then left in application for 24 hours. Following the completion of the 24 hour <br />period, the load was released and the sample disassembled. The geosynthetic <br />membrane was tested for punctures both visually and by application of a vacuum to the <br />geomembrane. The actual materials used and the specific observations of the test are <br />noted in the following sub-section. <br />3.1 Test #LLT-12 <br />LLT-12 was assembled by first placing approximately 4.5 inches of soil liner fill in the <br />bottom of the cell and then compacting as described in Section 3.0. Next, a 10 inch <br />diameter piece of 100 mil LLDPE geomembrane was placed on top of the soil liner fill <br />with the textured side down. Finally, the low volume solution collection fill material <br />was placed in one lift on top of the liner to a thickness of approximately six inches. <br />The sample was then loaded as described above for 24 hours after which time it was <br />disassembled and the geomembrane inspected for damage. The geomembrane sample <br />showed some minor signs of distress, i.e.: indentations and surface scratches, but <br />possessed no pinholes when held in front of a light source or during vacuum testing. <br />The post test condition of the geomembrane is shown in Figure 2. <br />4.0 Observations <br />In the test, minor amounts of distress were observed on the geomembrane sample. The <br />drainage material used for the geomembrane cover material showed no significant <br />change in particle size, although some of the larger particles did appear to have <br />cracked. No apparent changes were noticed in the soil linerfill. <br />If there are any questions or concerns about this report or the information contained in <br />it, please feel free to contact me at any time. <br />
