3.0 Test Configurations The test was assembled by compacting the soil liner fill material at approximately 95% standard proctor maximum density. Imbedded in the surface of the soil liner fill material, a rock measuring approximately 3.5 inches by 1.5 inches was painted orange and allowed to project above the plane of the soil (See Figure 2). The geomembrane sample was placed on top of this surface. It was then followed by the drain cover fill material to complete the soil profile. The sample was then loaded in 50 pounds per square inch (psi) per hour increments until the target pressure of 385 psi was reached. The full load was then left in application for 24 hours. Following the completion of the 24 hour period, the load was released and sample disassembled. The geosynthetic membrane was tested for punctures both visually and by application of a vacuum to the geomembrane. The actual materials used and the specific observations of the test are noted in the following sub-section. Atypical cross-section of the assembled material is shown in Figure 3. 3.1 LLT-11 Test number LLT-I1 was assembled by first placing approximately 4.5 inches of soil liner fill in the bottom of the cell, and then compacted as described in Section 3.0. Next, a 10 inch diameter piece of 80 mil LLDPE geomembrane was placed on top of the soil liner fill with the textured side down. Finally, the drain cover fill material was then placed in one lift on top of the liner to an approximate thickness of six inches. The sample was then loaded as described above for 24 hours after which time the sample was disassembled and the geomembrane inspected for damage. The geomembrane sample showed some minor signs of distress, i.e.: indentations, transfer of paint from the rock, and surface scratches, but possessed no pinholes when held in front of a light source or during vacuum testing. The post test condition of the geomembrane is shown in Figure 4. There appeared to be no movement, rotation, or translation of the rock that had been imbedded in the soil liner fill material. Photographic records of a cross- section of the soil liner fill material after the test was completed are not shown due to the inability to extract the sample in a fashion that left it intact. 3.2 LLT-11a As stated earlier, post test photographic documentation of the soil liner fill surface for test LLT-11 was not obtained due to difficulty associated with removing the sample from the testing apparatus. Therefore, the test was re-performed using new materials and the same rock with approximately the same orientation and location so as post test photographs could be obtained.
