October 2001 -16- 003-2182.004 <br /> 4.1.3 AtterbergLimits <br /> imits <br /> Golder performed Atterberg limit testing of all fill materials. All fill materials, with the <br /> exception of Soil Liner Fill were non-plastic. The testing frequency(approximately one test per <br /> 3000 cubic yards for Soil Liner Fill) exceeded the minimum specified testing frequency. The <br /> Soil Liner Fill, Leak Detection Fill, Pipe Bedding Fill, Structural Fill, and Base Course samples <br /> tested met project specifications for Atterberg limits. The plasticity index of the two CQA Soil <br /> Liner Fill samples was 29, which met the project specification of plasticity index greater than or <br /> equal to 10. Atterberg limit test results are presented in Appendix G-1 and summarized in <br /> Tables 4-8. <br /> 4.1.4 Proctor Compaction Tests <br /> Golder performed standard Proctor compaction tests of Soil Liner Fill and testable Structural <br /> Fill in order to compare in-place densities and moisture contents with laboratory derived values <br /> of maximum dry density and optimum moisture content. On Structural Fill samples where the <br /> amount of material larger than 3/4-inch particle size was less than or equal to that allowed by <br /> the ASTM D698 test method, a Proctor test was performed on samples of the Structural Fill <br /> used for site grading. <br /> Golder performed four CQA standard Proctor compaction tests of Structural Fill. The testing <br /> frequency (approximately one test per 14,400 cubic yards) exceeded the minimum specified <br /> testing frequency of one test per 50,000 cubic yards. The Structural Fill compaction test results <br /> are presented in Appendix G-2 and summarized in Table 4. CQC Proctor tests were not <br /> included in the Proctor testing frequency. <br /> Golder performed two CQA standard Proctor compaction tests of Soil Liner Fill. The testing <br /> frequency (approximately one test per 3,000 cubic yards) exceeded the minimum specified <br /> testing frequency of one test per 5,000 cubic yards.
