6.3 Sand 'for ' Class "A" fill is spread and leveled in ' layers not exceed-1 Ing 15 inctes prior to ccapaction, '

  • for Class "B" backfill is placed .in layers not exceeding e4gk inches prior to compaction. $7 l

m.w4 Fill material is deposited over entire area being filled to a parti-j y, 6.5 g cular stage or level.

l ,

t 6.6 When required, fill material shall be disc-harrowed after spreading

~"~

and before compaction to blend-and aerate the material into a tex-

'ture that can be consolidated into a homogeneous mass by the compac-tion operations. ,

6.7 Layers of fill material are placed to essentially equalize effective i

f pressure at the base of the mat.

' Surface of each lif t is kept reasonably smooth and free of' ridges or 6.8 grooves which would adversely affect proper compaction of subsequent

, lifts. .

694 . 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.

!t 6.10 if area,to receive fill is an original excavation, or compacted more i than two days previously, surfaces shall be cleaned of all loose debris and improperly compacted material.
