f ul fi l l ed. ,

6.1 Material has been determined to-be'sultable by Ebasco and released to J. A. Jones.

6.2 Backfilling is accomplished in the proper sequence in accordance

  • with Ebasco Drawing No. LOU-1564-G490.

l 6.3 Base to receive backfill has been properly prepared and compacted to the density required by Ebasco.

6.4 Sand for Class "A" fill is spread and leveled in layers not exceed-ing 15 inches' prior to compaction.

6.5 Clay for Class "A" backfill and material selected from the excavation for Class "B" backfill is placed in layers not exceeding ten inches-prior to compaction.

6.6 Fill material is deposited uniformly over entire area being filled to a particular stage or level.

6.7 When required, fill material shall be disc-harrowed af ter spreading and before compaction to blend and aerate the. material into a tax-ture that can be consolidated into a homogeneous mass by the com-paction operations.

6.8 Surface of each lift is kept reasonably smooth and free of ridges or grooves which would adversely affect proper compaction of subsequent lifts.

i 6.9 Hauling equipment uses paths different from each other in order to

aid compaction of the entire area and to avoid overcompaction of any given area.
