3.4 Moisture Content Liner fill material shall be placed and compacted at moisture contents from one percent below to three percent above optimum moisture content, as determined by Standard Proctor Moisture-Density Test, ASTM D-698. The moisture content of the fill material will be tested prior to and during compaction, every 500 cubic yards from samples along the embankment as determined by the Engineer. If required, additional moisture may be applied by evenly distributed sprinkling and conditioned by disking for each layer of fill. The moisture content will be consistent throughout each layer of material. Compacted materials that are not within the optimum moisture content range will be rejected. These materials that do not meet the optimum moisture content will be reworked until acceptable moisture content and compaction levels are obtained. Reworking methods may include removal, rehandling, reconditioning, rerolling or any combination of these methods. 3.5 Compaction The fill material will be placed in loose lift layers not more than 9-inches thick and will be compacted to at least 95% of the maximum dry density, as detemtined by the Standard Proctor density test as described in ASTM D-698. Fill material will be tested for dry density requirements every 5,000 cubic yards on embankment samples, as detenmined by the Engineer. Material that does not meet the maximum dry density requirement will be reworked until this requirement has been met. 3.6 Size of Clods Dry clods must be reduced to less than 3 inches, prior to compaction, which may be the case when using ripped shale as a liner material. Disc harrows, a road reclaimer or other similar equipment may be used to pulverize the material, prior to watering and compaction. 3.7 Excavation Excavation for the water storage area will be graded and maintained such that adequate drainage is provided at all times. The site will be excavated and graded as described in the DMG 112 Reclamation Permit.
