E. Protective Operations Layer Acceptance: <br /> ® 1. Final acceptance of the Protective Operations Layer will be based on tests <br /> made on completed Work on samples taken from the completed layer, on <br /> leak location testing and repair, and on thickness as determined by surveys <br /> of the top of GDM and Protective Operations Layers. Testing for final <br /> acceptance shall be performed by the QA/QC CONSULTANT in <br /> accordance with these Specifications and the CQA Manual. <br /> 3.15 GENERAL EARTHFILL <br /> A. Place material in minimum 8-inch lifts and compact each lift to minimum 90 <br /> percent relative compaction(ASTM D1557). <br /> B. Do not attempt to compact general earthfill that contains excessive moisture. <br /> Aerate material by blading, discing, harrowing, or other methods, to hasten drying <br /> process. <br /> C. Use hand-held compaction equipment, if necessary, when compacting general <br /> earthfill around HDPE Tanks. <br /> 3.16 ANCHOR TRENCH <br /> A. The EARTHWORK CONTRACTOR shall excavate the anchor trench as shown <br /> qW on the Construction Drawings. The EARTHWORK CONTRACTOR shall <br /> protect the trench from desiccation, sloughing, and flooding. <br /> B. All corners of anchor trench over which geosynthetic materials will be placed <br /> shall be rounded. <br /> C. Excavated material shall be placed at a sufficient distance from the edge of <br /> excavations to prevent cave-ins or bank slides. <br /> D. Backfill anchor trench when directed by GEOSYNTHETICS CONTRACTOR. <br /> Anchor trench shall be backfilled with general earthfill or slurry cement mixture <br /> as shown on the Construction Drawings or directed by the DESIGN ENGINEER <br /> or QA/QC CONSULTANT. General earthfill used as anchor trench backfill shall <br /> be compacted to 85 percent relative compaction per ASTM D1557. <br /> 3.17 BERMS <br /> A. Construct termination, perimeter and anchor berms of general earthfill as shown <br /> on the Construction Drawings. Place material in lifts not exceeding 1-foot depth <br /> (after compaction) and compact each lift to approximately 85 percent relative <br /> ® compaction (ASTM D1557). <br /> B. The EARTHWORK CONTRACTOR shall repair or replace any geosynthetic <br /> materials damaged during placement and compaction of the berms, at the <br /> Forward Landfill WMU FU-13 <br /> 02300 25 EARTHWORK <br />
