C. Select Structural Fill
Select Structural Fill shall be placed for miscellaneous site grading as
required by the MANAGER and CERTIFYING ENGINEER.
2. CONTRACTOR shall condition Select Structural Fill to a moisture content
that allows compaction to the required density and that results in a firm;
unyielding surface capable of allowing the movement of vehicles and
equipment over the surface without causing rutting or other deleterious
effects.
3. CONTRACTOR shall place Select Structural Fill materials with less than 30
percent rock materials above 3l4-inch size in maximum 12-inch loose lifts,
and compacted to 95 percent of maximum dry density (ASTM D6981.
4. CONTRACTOR shall condition and place Select Structural Fill containing
more than 30 percent rock materials above 3/4-inch size frock fill) in
maximum 12-inch loose lihs and compact by a method compaction
technique. The compaction equipment shall consist of a minimum ten 10-
ton Istatic drum weight) vibratory smooth-drum compactor. The number
of passes shall be subject to CERTIFYING ENGINEER'S approval, at no
additional cost to CC&V, The method SPECIFICATIONS may be changed
at any time, at the discretion of CERTIFYING ENGINEER, based upon
changes in material characteristics, field conditions, and/or compaction
equipment.
D. Underdrain Fill
1. Underdrain Fill shall be placed in the Secondary and Tertiary Underdrains
as shown in the DRAWINGS.
2. CONTRACTOR shall condition Underdrain Fill that results in a firm,
unyielding surface capable of allowing the movement of vehicles and
equipment over the surface without causing rutting or other deleterious
effects.
3. CONTRACTOR shall condition, place and compact Underdrain Fill by a
method compaction technique. The compaction equipment shall consist
of a minimum 10-ton (static drum weight) vibratory smooth-drum
compactor. The number of passes and loose lift thickness shall be subject
to CERTIFYING ENGINEER'S approval, at no additional cost to CC&V. The
method SPECIFICATIONS may be changed at any time, at the discretion of
MANAGER, based upon changes in material characteristics, field
conditions, and/or compaction equipment.
4. Provisions shall be made by CONTRACTOR for removal of oversize
materials from fills, at no additional cost to CC&V.
5. The MANAGER will minimize the amount of traffic over the Underdrain Fill.
E. Leak Detection Fill
1. Leak Detection Fitl shall be placed in the Leak Detection Trenches as
shown on the DRAWINGS.
