4.1.2 Moisture Content <br />amee? <br />AMEC performed sixty -seven (67) CQA gradations of SLF. The testing frequency <br />(approximately one test per 1,633 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 5,000 cubic yards. The CQA gradations performed of SLF met <br />project specifications. The SLF CQA gradation results met project specifications and are <br />presented in Appendix H -1 and summarized in Table 7. <br />AMEC performed twelve (12) CQA gradations of DCF. The testing frequency <br />(approximately one test per 18,237 cubic yards) exceeded the minimum specified testing <br />frequency of one test per 20,000 cubic yards. The DCF CQA gradations met project <br />specifications, and the results are presented in Appendix H -1 and summarized in Table 8. <br />AMEC performed one (1) CQA gradation of SSF. The testing frequency (approximately one <br />test per 315 cubic yards) exceeded the minimum specified testing frequency of one test per <br />50,000 cubic yards. The SSF CQA gradation met project specifications, and the results are <br />presented in Appendix H -1 and summarized in Table 9. <br />AMEC measured oven moisture contents of SF, LDF, SLF, DCF, and SSF as part of the <br />CQA program. Test results met or exeeced project specifications and are presented in <br />Appendix H.1 and Tables 5 through 9. <br />4.1.3 Atterberg Limits <br />AMEC performed Atterberg limits testing of the fill materials. All fill materials, with the <br />exception of SF and SLF, were non - plastic. The SLF, SF, DCF, SSF, and LDF samples <br />tested met project specifications for Atterberg limits. Atterberg limits test data are presented <br />in Appendix H.1. <br />AMEC performed fifty -five (55) CQA Atterberg limits tests of SF. The testing frequency <br />(approximately one test per 45,699 cubic yards) exceeded the minimum specified testing <br />AMEC Earth & Environmental, Inc <br />2000 S Colorado Blvd 2 -1000 <br />Denver, CO 80222 <br />Tel 303 - 935 -6505 <br />Fax 303 - 935 -6575 www.amec corn 18 <br />
