ameo <br />• <br />frequency of one test per 50,000 cubic yards. The SF compaction test results are presented <br />in Appendix H-2 and summarized in Table 8. CQC Proctor tests were not included in the <br />Proctor testing frequency. <br />AMEC performed standard Proctor compaction tests of SLF in order to compare in-place <br />densities and moisture contents with laboratory derived values of maximum dry density and <br />optimum moisture content. AMEC performed sixteen CQA Standard Proctor compaction <br />tests of SLF. The testing frequency (approximately one test per 3,334 cubic yards) <br />exceeded the minimum specified testing frequency of one test per 5,000 cubic yards. The <br />SLF compaction test results are presented in Appendix H-2 and summarized in Table 9. <br />CQC Proctor tests were not included in the Proctor testing frequency. <br />AMEC performed one standard Proctor compaction test of LVSCF in order to compare <br />in-place densities and moisture contents beneath PSSA riser base plates and in the PSSA <br />anchor trench for LVSCF with laboratory derived values of maximum dry density and <br />optimum moisture content. There is no testing frequency for LVSCF. The LVSCF <br />compaction test result is presented in Appendix H-2 and summarized in Table 10. CQC <br />Proctor tests were not included in the Proctor testing frequency. <br />4.1.5 Permeability Tests <br />AMEC conducted permeability tests of SLF. AMEC conducted sixteen permeability tests of <br />re-compacted samples of SLF. The testing frequency (approximately one test per <br />3,334 cubic yards) exceeded the minimum specified testing frequency of one test per <br />4,000 cubic yards. Testing was performed with a flexible-wall permeameter with <br />back-pressure saturation and a constant rate of flow (ASTM D5084, Method D). The fill was <br />re-compacted to the in-place density measured during nuclear density tests and the <br />corresponding moisture content (as determined from oven-dried samples). The nuclear <br />density value measured in the field was corrected for coarse particles according to <br />ASTM D4718. Laboratory tests yielded coefficients of permeability for the CQA samples <br />from 8.8 x 10-7cm/sec to 2.2 x 10-acm/sec, all of which are less than the specified maximum <br />• <br />AMEC Earth & Environmental, Inc. <br />2000 S.
