August 2002 -23- 003 -2203 <br />Golder performed 2 CQA gradation of Pipe Bedding Material (PBM). No testing frequency <br />• was identified in the CQA Plan for this material. The CQA gradation performed on PBM. met <br />project specifications. The PBM gradation results are presented in Appendix I -1 and <br />summarized in Table 12. <br />Golder performed 1 CQA gradation of Granular Filter Material. (GFM). No testing frequency is <br />identified in the CQA plan for this material. The CQA gradations performed of GFM met <br />project specifications. The GFM CQA gradation results are presented in Appendix I -1 and <br />summarized in Table 18. <br />4.1.2 Moisture Content <br />Golder measured oven moisture contents of UF, SSF, FSB, PBM, LDF, SF, SSF, SLF and <br />DCF as part of the CQA program. Moisture content data were presented in Appendix I -1. <br />4.1.3 Atterber Limits <br />Golder performed Atterberg limit testing of all fill materials. All fill materials, with the <br />exception of SF and SLF were non - plastic. The SLF, SF, UF, LDF, DCF, FSB, and PBM <br />samples tested met project specifications for Atterberg Limits. <br />The testing frequency (approximately one test per 4,413 cubic yards for SLF) exceeded the <br />minimum specified testing frequency. The plasticity index of the CQA SLF samples ranged <br />from 22 to 29, meeting the project specification of plasticity index greater than or equal to 10. <br />Atterberg limit test results for SLF are presented in Appendix I -1 and summarized in Table 9. <br />I:1 O=03404001CUIRWMZ 03=03.040004740 tdoe Golder Associates <br />
