2005 -2- <br />2.0 MATERIAL DESCRIPTION <br />053-2386 <br />Three different soil materials and three geosynthetic materials were used to complete the testing <br />program consistent with the VLF construction. These materials aze described by their properties and <br />referred to by name for consistency during discussion of the test procedures. <br />2.1 Soil Materials <br />Three types of soil material were provided for testing and aze listed below: <br />1. Drain Cover Fill (DCF); <br />2. Low Volume Solution Collection (LVSC) Fill; and <br />3. Soil Liner Fill (SLF). <br />All of the soil materials for the liner load tests were collected by Golder and obtained from material <br />stockpiles produced as part of the 2003-2004 Phase N construction activities. <br />Prior to testing, the DCF and LVSC Fill materials were air dried then separated by grain size. The <br />grain size results aze included in Appendix A. The materials meet the gradation requirements for <br />DCF and LVSC Fill specified in the Phase N VLF Technical Specifications. The specified DCF and <br />LVSC Fil] gradations are summazized in Tables 2-1 and 2-2, respectively. <br />Preparation of the SLF material included air drying and separation by grain size. The soil was <br />screened over the 2-inch sieve to remove oversized material and processed by passing it through a <br />I No. 4 sieve. Soil clods between the No. 4 and 2-inch sieves were broken by hand and mixed with the <br />No. 4 material to simulate field soil prepazation conditions. The SLF material met the gradation <br />requirements specified in the Phase N VLF Technical Specifications, summarized in Table 2-3. <br />Prior to testing, the SLF was moisture treated and compacted according to the Phase IV VLF <br />Technical Specifications. <br />2.2 Geosynthetic Materials <br />Samples of textured 80-mil LLDPE and smooth 100-mil LLDPE geomembrane were supplied by <br />Polyflex for the liner load testing program. A sample of 80-mil textured VLDPE geomembrane was <br />i\OSQ3B6\0400\fvl-Iicnloedmpp0606\0532386.0400 fNrep.doc Golder Associates <br />
