M 11 <br />AMEC performed seventy -three (73) CQA Atterberg limits tests of SLF. The testing <br />frequency (approximately one test per 705 cubic yards) exceeded the minimum specified <br />testing frequency of one test per 5,000 cubic yards. The CQA Atterberg limits performed of <br />SLF met project specifications. The SLF CQA Atterberg limits results are summarized in <br />Table 7. <br />AMEC performed eleven (11) CQA Atterberg limits tests of DCF. The testing <br />frequency (approximately one test per 9,362 cubic yards) exceeded the minimum <br />specified testing frequency of one test per 20,000 cubic yards. The DCF CQA <br />Atterberg limits met project specifications, and the results are summarized in <br />Table 8.4.1.4 Proctor Compaction Tests <br />AMEC performed standard Proctor compaction tests of SF in order to compare in -place <br />densities and moisture contents with laboratory derived values of maximum dry density and <br />optimum moisture content. The majority of the SF contained more than 30 percent above <br />the % -inch sieve. Per Specification 2200 Section 3.06, SF containing more than 30 percent <br />above the % -inch sieve is placed using a method specification and cannot be tested using a <br />standard Proctor (due to the high rock content). Of the SF placed containing less than 30 <br />percent above the % -inch sieve (approximately 128,400 cubic yards), AMEC performed six <br />(6) CQA standard Proctor compaction tests, resulting in one test per 21,400 cubic yards, <br />exceeding the testing frequency of one test per 50,000 cubic yards. The SF compaction test <br />results met project specifications and are presented in Appendix H -2 and summarized in <br />Table 5. CQC Proctor tests were not included in the 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.
