1.01 Contractor shall furnish all plant, materials, labor, and equipment
required for completing the grading work, roadway, and related
drainage facilities as shown on the contract drawings. Volumes
of fill and excavation are calculated as "solid volumes." All
work shall be conducted in strict accordance with these specifi-
cations and attached contract drawings.
2.00 GENERAL PROVISIO14S
2.01 Classification
2.01.1 Fill - Approved fill material shall be considered clean soil,
free of large stone, rock, and organic matter. The maximum
dimension of any rock or stone, as placed, shall not exceed
a two and one-half (2-1/2) foot vertical dimension or not
exceed one fourth (1/4) the depth of fill at its point of
placement. Fragments or solid rocks more than six (6) inches
in maximum dimensions are not permitted in the upper two (2)
feet of fill. All fill shall be free of frost. Fill material
shall not be placed on frozen ground. If rock is used, it
shall be placed at the toe of the fill but shall not conflict
with other provisions provided for in this specification.
Before placing the fill, all topsoil and/or organic matter
shall be removed.
2.01.2 Excavation - Excavation will not be classified and will include
all materials encountered, regardless of nature.
2.02 Compaction - The maximum layer of fill shall not exceed nine (9)
inches. A minimum of three (3) passes with either a smooth
wheel roller of minimum ten ton capacity or a sheepsfoot roller
shall be used depending on the nature of soil encountered. The
sheepsfoot roller shall have a minimum bulb pressure per knob
of 200 pounds per square inch. The area of the knobs shall be
at least five (5) percent of the total peripheral area of the
drum, using the diameter measured to the faces of the knobs.
Fills shall be compacted to ninety-five (95) percent of Standard
Proctor Density. Moisture shall be controlled if necessary to
+ two (2) percent of optimum. The subgrade in both cut and
fill sections shall be compacted to ninety-five (95) percent of
Standard Proctor Density and shaped to conform to the typical
sections prior to placing stone. The Contractor shall provide
the Owner with access and necessary assistance to perform in -
place density tests of the compacted fill.

2.07.2 Continued - The material used for blending must meet the quality
requirements of the crusher -run stone, crusher -run gravel or
crusher -run slag as herein prescribed and must be proportioned
and uniformly blended with the crusher -run stone, crusher -run
gravel or crusher -run slag to conform to the gradation require-
ments of this item. Blending can be performed by the method of
pug mill operation, but not by road mixing. When the Contractor
elects to blend material, the gradation for the middle of the
band shall be attempted for the finished product. Each type of
crusher -run aggregate, whether used alone or in combination,
shall have a maximum Los Angeles Abrasion Loss of sixty-five
(65). The plasticity index of the material passing the No. 40
mesh sieve, on each type of aggregate used, shall not be greater
than six (6) reported to the nearest whole number and the liquid
limit of the material passing the No. 40 mesh sieve, on each
type of aggregate used, shall not be greater than twenty-five
(25) reported to the nearest whole number. The methods of tests
to be utilized in determining the above requirements shall be
as follows:

main road with a uniform transition from one pavement to the
other. When the roadway crosses a drainage ditch of the main
road, the roadway shall be depressed or a corrugated drain
pipe shall be installed to insure unobstructed flow in the
drainage ditch. The type of connection to the main road shall
be as specified and approved by the municipal authority having
jurisdiction over the main road.
2.07.4 Construction Equipment - Equipment for construction shall be
approved by the Owner's representative prior to construction
operations under this section. Any machine, combination of
machines or equipment which will handle the material without
undue segregation and produce the completed surface course
meeting these specifications for handling, spreading, moistening,
mixing, and compacting may be used on approval. If power graders
are used for spreading, the material shall be placed in windrows,
uniformly and thoroughly mixed, prior to final spreading and
compaction. Roller and method of rolling shall be such that
maximum density is obtained. After final compaction, the thick-
ness of the compacted stone shall be checked at random locations
by the Contractor in company with the Owner's representative.
A minimum of five (5) checks will be made. In the event that
deficiencies are found, additional checks shall be made to
define the limits of the deficient areas. Any deficiency in
excess of one-half (1/2) inch shall be corrected.
