3. Each load of the material placed in the embankment, whether from excavation for other parts of the Work or from the borrow pit, shall be placed in accordance with the plans and specifications. 4. In any separate portion of liner embankment being constructed, each layer shall be constructed continuously and approximately horizontal for the width and length of such portion at the elevation of the layer, with the exception of the ends of the fill section which can be constructed at maximum 3:1 slopes or flatter. When the portions of the liner are extended laterally to connect to an existing portion of the liner the existing liner shall be overexcavated to firm, properly moisture conditioned embankment prior to placement of new fill adjacent to the existing fill. 5. The Contractor shall maintain the embankment in an approved manner, including maintaining surfaces free of weeds or other vegetation, until final completion and acceptance of all the work under the Contract. 6. During temporary shutdown periods, or winter shutdown periods, the embankment shall be protected by "dry lifting" and minimum of 1 foot depth over the fill to protect from frost. Prior to resuming the placement of embankment material after temporary or winter shutdown periods, the Contractor shall remove the "dry lift" material, and overexcavate the existing surface down to firm, properly moisture conditioned fill prior to new fill placement. The depth of the overexcavation shall be approved by the Engineer. Prior to placement of new fill the area shall be scarified and moisture conditioned to specified moisture limits.. D. RATE OF PLACEMENT Unless otherwise directed by the Engineer, the embankment shall be maintained at approximately the same level regardless of the number of types of materials being placed, except that the adjoining Zone III dewatering material shall be placed with sufficient lag to prevent mixture of embankment and Zone III materials. E. MAINTENANCE AND PROTECTION OF EMBANKMENT MATERIALS The Contractor shall maintain and protect the embankment in a satisfactory condition at all times until final completion and acceptance of all work under the Contract. If in the opinion of the Engineer, the hauling equipment causes horizontal shears or slick sides, rutting, quaking, heaving, cracking or excessive deformation of the embankment, the Contractor shall limit the type, load or travel speed of the hauling equipment on the embankment. 2. Any approved embankment material which is lost in transit or rendered unsuitable after being placed in the embankment and before final acceptance of the Work, shall be replaced by the Contractor in a satisfactory manner. 3. The Contractor shall excavate and remove from the embankment any material that the Engineer considers objectionable and shall also dispose of such material and refill the excavated area as directed.
