~J <br /> <br /> <br />June 24, 2003 -25- <br />4.1.3 Atterber Lg units <br />003-2203.7 <br />Golder performed Atterberg limit testing of all fill materials. All fill materials, with the exception of <br />SF and SLF were non-plastic. The SLF, SF, UF, LDF, BF, LVSCF, DCF, SDCF, and FSB samples <br />tested met project specifications for Atterberg Limits. <br />The SLF Atterberg limits testing frequency (approximately one test per 3,827 cubic yards) exceeded <br />the minimum specified testing frequency of one test per 5,000 cubic yards. The plasticity index of the <br />CQA SLF samples ranged from 24 to 28, meeting the project specification of plasticity index greater <br />than or equal to 10. Atterberg limit test results for SLF are presented in Appendix [-1 and <br />summarized in Table 9. <br />The SF Atterberg limits testing frequency (approximately one test per 47,341 cubic yards) exceeded <br />the minimum specified testing frequency of one test per 50,000 cubic yards. The plasticity index of <br />the SF varied from NP to 15 and met project specifications. Atterberg limit test results for SF are <br />presented in Appendix I-1 and summarized in Table 8. <br />4.1.4 Proctor Compaction Tests <br />Golder performed standard Proctor compaction tests of SLF in order to compare in-place densities <br />and moisture contents with laboratory derived values of maximum dry density and optimum moisture <br />content. Golder performed eight CQA Standard Proctor compaction tests of SLF. The testing <br />frequency (approximately one test per 3,827 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 5,000 cubic yards. The SLF compaction test results are presented in <br />Appendix I-2 and summarized in Table 9. CQC Proctor tests were not included in the Proctor testing <br />frequency. <br />Golder performed one standard Proctor compaction test of LVSCF in order to compaze in-place <br />densities and moisture contents beneath PSSA riser base plates for LVSCF with laboratory derived <br />values of maximum dry density and optimum moisture content. There is no testing frequency for <br />LVSCF. The LVSCF compaction test result is presented in Appendix I-2 and summarized in <br />Table 11. CQC Proctor tests were not included in the Proctor testing frequency. <br />z:~ao~zzm~oaoo~rmC~nessnoeosooszzoz.oaoo.ovzars~p.e« Golder Associates <br />
