amec?r <br />A CAT 385 excavator was used to excavate material between stations J6+00 (+/-) and J10+00 <br />(+/-), approximately 75 to 100 feet left of centerline. The material was loaded into CAT 740 <br />articulating haul trucks and placed between stations K8+00 (+/-) and K11+00 (+/-), <br />approximately 200 to 220 feet left of centerline. Fill was placed in 24" lifts using a CAT D-8 <br />dozer. Each lift was moisture conditioned using a tandem-axel water truck (when necessary) <br />and compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill <br />surface at least 4 times (method compaction technique was applicable). <br />D) Soil Liner Fill <br />1) VLF <br />Soil liner fill material was hauled and stockpiled in temporary stockpiles near stations A26+00 <br />(+/-) and H27+00 (+/-) using 40 ton articulating haul trucks loaded by a CAT 385 excavator. <br />The SLF was hauled from the East Cresson Clay process (see Figure 2 for previous soil liner <br />fill placement). <br />Soil liner fill (SLF) placement continued in the areas shown on Figure 2, hauling from the East <br />Cresson Clay borrow and temporary stockpile locations. Subgrade was approved and <br />moisturized prior to placement using a tandem-axel water truck. Placement was performed <br />using a CAT D-6 LGP dozer, a CAT D-7 LGP dozer and a CAT D-8 dozer in a one-foot <br />compacted lift. Moisture conditioning of SLF material was performed using a tandem-axel <br />water truck and compaction was achieved using a 10-ton vibratory smooth drum compactor. <br />Nuclear density testing, moisture verification, and depth checks were all performed, producing <br />results within project specifications. Test locations were surveyed by Ames. <br />E) Low Volume Solution Collection System <br />1) Low Volume Solution Collection Piping <br />No work performed during the week. <br />2) Low Volume Solution Collection Fill (LVSCF) <br />No work performed during the week (see Figure 5 for previous LVSCF placement). <br />F) High Volume Solution Collection System <br />1) High Volume Solution Collection Piping <br />Placement of the high volume collection system continued at the DCF placement area shown <br />on Figure 6, advancing in front of the placement. CPeP was placed and sandbagged in <br />accordance with design drawings and project specifications. The primary geomembrane in the <br />area was accepted prior to pipe placement. <br />2) Drain Cover Fill (DCF) <br />Drain cover fill (DCF) placement within the Phase 5 VLF started. DCF was placed in the area <br />show on Figure 6. Haul routes, which consisted of five-foot lifts, were spread into two-foot <br />lifts. The DCF was placed in a 2-foot lift using a CAT D-7 LGP dozer and a CAT D-8 LGP <br />dozer except where haul routes were established. Laborers were present at all times during <br />VLF Weekly Report WE 08.21.10.D.docx
