(e) Layers of material other than rockfill shall not exceed 150 mm compacted depth unless and until the Contractor can demonstrate to the satisfaction of the Engineer that he can successfully compact layers of a greater thickness. (f) Each shall be constructed in lengths suitable to the compaction and working methods used. Materials of each layer shall be thoroughly mixed with water as necessary to facilitate its compaction to the specified density. (g) In cut areas, the subgrade shall be processed as necessary and compacted to the depth and compaction requirements as given in Table 6.1 and Table 6.2. In the event that the Contractor is unable to achieve the minimum compaction requirements below formation level he shall excavate and recompact in layers as necessary.
