CV <br />AV <br />L! <br />TI M, <br />placed for the PSSA Toe berm, was keyed into the existing HWY embankment as fill lifts were brought up. <br />Progress is expected to continue. <br />See Hwy 67 embankment fill below for additional detail on materials placed. <br />Note: An Amec field representative monitored structural fill material temperatures placed within the areas of fill <br />during all shifts. Average structural fill temperatures were above 32 °F. <br />Clay (SLF) Processing: <br />Cameron Site: Clay processing resumed during this reporting period. Approximately, 175,540 tons of clay has <br />been processed to date. <br />Squaw Gulch Site: Clay stripping and stockpiling occurred during this reporting period. <br />Underdrain System: <br />Secondary Underdrain: No work was performed on the Secondary underdrain during this reporting period. <br />A total of 1380 feet of Secondary underdrain has been completed. <br />Primary Underdrain: No work was performed on the Primary underdrain during this reporting period. <br />A total of 1280 feet of Primary underdrain has been completed. <br />Temporary Underdrain: No work was performed on the temporary underdrain during this reporting period. <br />Tree /Slash Clearing, Chipping: <br />Seed Masters paused operations until further notice. <br />B) Underground Workings <br />Exploratory excavation was performed on underground working No.U6273, No.U6274, , and No.6132. These sites <br />require further excavation and exploratory efforts. <br />Confirmatory drilling was not performed during this reporting period. <br />Underground Working No. 6147 requires geogrid and will be prepared for this application as remediation efforts <br />continue. <br />Underground Working No. 6187 requires geogrid and will be prepared for this application as remediation efforts <br />continue. <br />Underground Working No. 6239 required geogrid. Remediation efforts completed. <br />No other sites were remediated during this reporting period. <br />Q Highway 67 <br />During this reporting period, R -value material equal to or above 40 (R 40 material) was placed and compacted at the Highway <br />67 realignment embankment. <br />A Cat 160M Grader with GPS continued to rip and work the R 40 material that has already been placed due to areas of high <br />moisture. Dryer R-40 material was mixed in during the process and areas in question were repaired. <br />The top grade of the sub -base was established during this reporting period and a Cat CS56B vibratory, 10 -ton, smooth-drum <br />roller completed the minimum of four passes over the lift surface (per method specification).
