ameO <br />• Permeability (ASTM D5084, Method D); <br />• In-place density testing (ASTM D2922); <br />• Soil description (ASTM D2488); <br />• Bulk specific gravity (ASTM C127; and <br />• Point Load Strength Index (ASTM D5731, Method D). <br />0 <br />AMEC conducted appropriate tests as required by the specifications for UF, SSF, CSB, SF, <br />SLF, LVSCF, DCF, and SDCF. <br />The laboratory test results are summarized in Tables 6 through 12 and presented in <br />Appendix H. <br />4.1.1 Grain Size Distribution <br />AMEC analyzed the grain size distribution (gradation) of samples of UF, SSF, SF, SLF, <br />LVSCF, DCF, and CSB. The results of gradation analyses are presented in Appendix H-1 <br />and summarized in Tables 6 through 12. <br />AMEC performed three CQA gradation of UF. The testing frequency (approximately one <br />test per 59 cubic yards) exceeded the minimum specified testing frequency of one test per <br />5,000 cubic yards. The CQA gradation of OF met project specifications. The OF CQA <br />gradation results are presented in Appendix H-1 and summarized in Table 6. <br />AMEC performed four CQA gradation of the SSF. The testing frequency (approximately one <br />test per 221 cubic yards) exceeded the minimum specified testing frequency of one test per <br />50,000 cubic yards. The CQA gradations of SSF met project specifications. The SSF CQA <br />gradation results are presented in Appendix H-1 and summarized in Table 7. <br />AMEC performed fifty-three CQA gradations of SF. The testing frequency (approximately <br />one test per 47,415 cubic yards) exceeded the minimum specified testing frequency of one <br />test per 50,000 cubic yards. The CQA gradations performed on SF met project <br />AMEC Earth & Environmental, Inc. <br />2000 S.
