Common use of Earth fill placement and compaction Clause in Contracts

Earth fill placement and compaction. The fill material shall be deposited in horizontal layers. The thickness of each horizontal layer before compaction shall normally be about 22.5 cm to 25.00 cm or as determined by the Engineer-in- Charge depending up on the type of compaction equipment. It may be possible to place thicker layers if heavy duty vibratory power rollers are deployed for compaction. The initial moisture content should be maintained to almost OMC (optimum moisture content). Water may be added through fine spray nozzles, whenever so warranted, in order to achieve OMC. The placing operation shall be such that the soil layers when compacted will be blended sufficiently to secure the highest practicable density and best impermeability and stability. Clouds and stones of size more than 7.5 cm shall be removed from the layer prior to compaction. If the surface of any compacted layer or earth fill is too dry or too smooth to bond properly with the layer to be placed there-on, it shall be moistened and/or scarified in an approved manner to provide a satisfactory bonding surface before the next/succeeding layers is placed.
