<br />' The following gradation limits were adopted for the Type 1 raise 2 embankment fill material. <br />' U.S. Standard Sieve Size % Finer By Weight <br />6 inch 100 <br />' 3/8 inch 65-100 <br />No. 4 45/95 <br />' No. 10 25-85 <br />No. 40 5-70 <br />No. 200 0-35 <br />Where significant oversize material was encountered in the fill material, as Flaced on the <br />embankment, this oversize was removed by working to the outside and inside slope: of the raise, <br />or broken down in-place by the weight of the fill compaction equipment. <br />' Embankment raise fill was compacted to a minimum of 85 percent of the maximum dry density <br />(ASTM D-698). The fill was placed in maximum one and a half foot thick loose lifts and <br />compacted through trafficking by over-the-road bottom dump eighteen wheel semi-trucks and <br />a 12-ton, Caterpillar Model CP-563, vibrating, sheeps-foot compactor. Haul tru<:k traffic was <br />' routed by the 14G Motor Grader operator, to provide coverage of the fill. The entire thickness <br />of each lift was tested for minunum density requirements as set forth in the Technical <br />Specifications and was found to meet these requirements. On the shoulders of the embankment <br />and access ramps, the sheeps-foot compactor was utilized to achieve passing densities. <br />The results of the QA/QC testing for the embankment raise fill are presented in Appendix A of <br />this report. <br /> <br /> <br /> <br /> <br />' S <br />1 <br />
