[HISTORY: Adopted by the Town Board of the Town of Cato 11-1-1988.
Section A121-1 amended at time of adoption of Code; see Ch. 1, General Provisions,
Art. I. Other amendments noted where applicable.]
A sixty-foot right-of-way, twenty-foot road surface, five-foot shoulders
and proper ditches for drainage shall be required.
Plans showing original and finished grades and plans showing proposed
drainage facilities shall be submitted to the Town Planning Board and the
Town Superintendent of Highways before final subdivision plot approval can
be given. No construction shall be commenced until such approval has been
given.
A.
General.
(1)
The contractor shall remove all rock, earth and other
material required by the plans for the full width of the road property. He
shall dispose of this material as required.
(2)
Earth embankments shall be constructed to established
lines and grades for the full width of the road property at the locations
shown on the plans. Embankment material shall be natural soil free from excessive
moisture, frost, stumps, trees, roots, sod, muck, marl, vegetable matter or
other unsuitable materials. Embankment material shall be obtained from approved
borrow pits and shall be well graded from fine to coarse with a minimum content
of silt.
(3)
Where embankments are to be placed under water, only
acceptable granular material shall be used. All materials shall be suitable
for compaction in layers not exceeding eight inches in thickness and shall
remain stable when wet.
B.
Stripping.
(1)
Prior to the commencement of excavation or fill, stripping
shall be conducted to remove topsoil, roots, organic matter, rubbish or other
debris for the full width of the road property.
(2)
Usable topsoil from stripping shall be stockpiled for
future use in piles at approved locations outside the limits of the road property.
C.
Materials to be used. If there is not sufficient excavated
material of a suitable quality at the site to complete the embankment, subgrades
and backfilling to the required lines and grade, the contractor shall borrow
the necessary additional materials. The source and acceptable ability of the
borrow material shall be subject to the approval of the Highway Superintendent
at all times. The contractor shall request the Highway Superintendent's
approval of proposed borrow areas at least five days before taking any material
from such areas. All test pits, explorations and laboratory tests required
by the Highway Superintendent to evaluate the acceptability of borrow shall
be done by the contractor at his own expense.
D.
Placing.
(1)
In general, embankment materials shall be placed in horizontal
layers not exceeding eight inches in thickness, measured after compaction,
and shall be thoroughly compacted. Stones, in any layer, shall not exceed
six inches in greatest dimension and shall be well distributed through the
mass.
(2)
Each layer of embankment material shall be thoroughly
tamped or rolled to the required degree of compaction by sheepsfoot or pneumatic
rollers, mechanical tampers or vibrations. Successive layers shall not be
placed until the layer under construction has been thoroughly compacted.
(3)
Trucks or other heavy equipment shall not be operated
over pipelines until a minimum of 36 inches of backfill above the crown of
the pipe has been placed and properly compacted.
E.
Compaction control.
(1)
Embankments shall have a minimum dry density of 95% of
the maximum dry weight density in pounds per cubic foot as determined by the
American Association of State Highway Officials standard density test for
the Proctor compaction test.
(2)
All laboratory tests required by the Highway Superintendent
shall be done by an approved testing laboratory at the contractor's expense.
(3)
When the test results indicate that insufficient compaction
has been obtained in any layer, the contractor shall take such action as the
Highway Superintendent may direct to modify or alter the moisture content
of the soil, to provide additional compaction or otherwise to increase the
in-place soil density.
The contractor shall prepare the subgrade to receive pavement in conformity
with the lines and grades as shown on the plans. Before the base material
is placed upon the subgrade, it shall be shaped to line and grade and compacted
with an approved self-propelled roller weighing not less than 10 tons. All
hollows and depressions which develop under rolling shall be filled with acceptable
granular material and shall again be rolled. Granular materials used to fill
depressions shall consist of approved hard, durable particles. This process
of shaping and rolling and filling shall be repeated until no depressions
develop. The subgrade shall not be muddy or otherwise unsatisfactory when
the base material is placed upon it. If soft spots develop during the rolling,
the material shall be removed and replaced with acceptable granular material
as above.
Base course requirements shall be 12 inches of gravel and four inches
of crusher run.
Other requirements shall be one coat of penetrating oil and stone and
one coat of oil and stone.
There shall be proper size culvert pipes for drainage.
A.
Rough grading must be completed before construction of
any utilities is commenced.
B.
The subgrade must be inspected and approved by the Town
Highway Superintendent before the base course is placed.
C.
No part of the surface course shall be constructed until
written permission is given by the Town Highway Superintendent.
D.
The base course must be inspected and approved by the
Town Highway Superintendent before the binder course is placed.
E.
Written permission to apply the oil-and-chip top coat
will be given by the Town Highway Superintendent no sooner than one year after
approval of the binder course. At this time, the contractor shall make repairs
as directed by the Town Highway Superintendent and shall clean the pavements
and gutters before placing the oil-and-chip coat.
F.
A performance bond will be posted by the contractor to
cover the entire cost of the construction project.
