May 2005 -E- 053-2386 <br />transmit more stress on the liner due to higher point loads. Also the thin SIX layer is "stiffer" than <br />field conditions, thereby providing an unyielding surface. The test configulation does not <br />compromise the liner test results and is considered to be representative of "worst case" loading <br />conditions. <br />The test sample was loaded in 50 pounds per square inch (psi) increments over a 53-hour period until <br />the target pressure of 850 psi was reached. The full load of 850 psi was maintained for 28 hours. <br />Following completion of the 28-hour period, the load was released and the sample disassembled. The <br />geosynthetic membrane was inspected and tested for punctures both visually and by applying a <br />vacuum to the geomembrane. Liner load test results for his configuration are included in <br />Appendix B-1. Test results are discussed in Section 5. <br />4.2 Test #2 - Phase 1V PSSA Liner System <br />The test sample was assembled using approximately 5.9 inches of LVSC Fill in the bottom of the cell. <br />Next, a 12-inch diameter piece of 100-mil smooth LLDPE geo:membrane was placed on top of the <br />LVSC Fill material. Finally, the DCF material was placed on top of the liner to a thickness of <br />4 <br />approximately 5.5 inches. The thickness of SLF and DCF placed in the load cell is not representative <br />of field conditions due to the small size of the testing apparatus. <br />The test sample was loaded in 50 pounds per square inch (psi) increments over a 24-hour period until <br />the target pressure of 630 psi was reached. The full load of (130 psi was maintained for 24 hours. <br />Following completion of the 24-hour period, the load was released and the sample disassembled. The <br />geosynthetic membrane was inspected and tested for punctures both visually and by applying a <br />vacuum to the geomembrane. Liner load test results for this configuration are included in <br />Appendix B-2. Test results are discussed in Section 5. <br />43 Test #3 - Phase IV PSSA Liner System <br />The test sample was assembled using approximately 4.9 inches of LVSC Fill in the bottom of the cell. <br />Next, a 12-inch diameter piece of 100 mil smooth LLDPE geomembrane was placed on top of the <br />LVSC Fill material. Finally, the DCF material was placed on top of the liner to a thickness of <br />/ approximately 6.0 inches. The thickness of SLF and DCF placed in the load cell is not representative <br />of field conditions due to the small size of the testing apparatus. <br /> <br />kV= 71$&O$00. **dec Golder Associates
