SECTION 02219

I

within the area to be cove~ed by embankment, and which
extend below or beyond the established lines of excavation
for dam embankment foundations, shall be filled with
embankment materials and compacted as specified for the
overlying embankment.

I

I

C. The foundation for the earthfill, except surfaces of
formation materials, shall be prepared by leveling,
moistening, and rollin9 so that the surface materials of
the foundation will be as compact and will provide as
satisfactory a bonding surface with the first layer of the
earthfill as specified for the subsequent layers of the
earthfill.

I

I

D. Immediately prior to placing the first layer of earthfill,
all surfaces upon or against which the earthfill protions
of the dam embankment are to be placed shall be cleaned of
all loose and objectionable materials in an approved
manner by handwork, barring, picking, brooming, sluicing,
or by other effective means. Such surfaces shall have all
water removed from depressions and shall be properly
moistened and sufficiently clean to obtain a suitable bond
with the earthfill.

3.03 MOISTRUE AND DENSITY CONTROL

A. General

I

1. Each layer of the material on the embankment shall be
compacted by a minimum of 12 passes of the tamping roller
which shall be the minimum compacting effort to be
performed by the Contractor. During compaction, the
placement moisture content ~nd dry density of the
earthfill shall be maintain@d within the control limits
specified below.

2. To determine that the moisture content and dry density
requirements of the compacted earthfill are being met,
field and laboratory tests will be made on samples taken
at embankment locations determined by the Engineer. Field
and laboratory tests will ~e made by the Engineer or his
agent. The results of all completed earthwork tests will
be available to the Contractor. Tests will be made at a
minimum of one per each day or part day of embankment
placement. Additional tests will be made by the Engineer
or his agent if conditions warrant. These conditions may
consist of contractor's con~truction methods, construction
inactivity, inclement weather or other conditions as
determined by the Engineer.

3. Materials not meeting the specified moisture content
and dry density requirements, as determined by the tests,
shall be reworked until specified results are obtained.
Reworking may include removal, rehandling, reconditioning,
rerolling, or combinations of these procedures. The
