(3)
When the subgrade is completed, the contractor shall
so notify the Town Highway Superintendent and the Town Engineer for
a base determination (proof roll). Upon the review and written approval
of the subgrade by the Highway Superintendent and the Town Engineer,
the base material may be placed.
B.
Base material.
(1)
Approved base materials shall be uniformly deposited
and compacted in layers with a roller, according to NYSDOT specifications.
Rolling shall begin at the sides and continue toward the center and
shall continue until there is no movement of the course ahead of the
roller. After compaction, the top surface of this course shall not
extend above the theoretical elevation for this course and when tested
with a straightedge 16 feet in length, any bump or depression over
1/4 inch from the theoretical grade line shall be satisfactorily eliminated.
When the base has been prepared to the satisfaction of the Highway
Superintendent, the developer may place the binder course. If base
conditions are changed as determined by the Highway Superintendent
before the binder is placed, he/she may order the developer to seal
the stone with a rapid-sealing liquid asphalt emulsion as specified
in NYSDOT Section 702-10 or 702-11 with 0.5 gallon per square yard
as determined by the conditions and not more than 24 hours prior to
placement of binder asphalt.
(2)
If the compaction of the base is questionable by the
Highway Superintendent, it may require rerolling or stone replacement
by the developer.
C.

(1)
Binder shall be placed and compacted to a minimum
finished layer thickness of three inches with a self-propelled asphalt
spreader and rolled according to NYSDOT Specifications 401-3.06 and
401-3.12. Before applying the top course, any irregularities in the
binder course shall be eliminated but at no time will "cold patch"
or "winter mix" be allowed on the binder for repair work.
(2)
Before the surface course is placed, the binder will
be cleaned for inspection by the Highway Superintendent to determine
the condition of the pavement. It may be necessary to apply a tack
coat at the rate of 0.1 gallon per square yard before placing the
surface.
(3)
Surface course shall be placed and compacted to a
minimum finished layer thickness of 1 1/2 inch with a self-propelled
asphalt spreader and rolled in accordance with NYSDOT Specifications
401-3.06 and 401-3.12.

Concrete gutters shall be a minimum of six inches
in depth and constructed true to the shape, line and grade on a thoroughly
compacted base. The gutters may be constructed using a slip form method
or in-place formwork.
(2)
Joints between sections shall be placed every 10 feet
at right angles to the flow line and must be "wet struck" 1/8 inch
wide and 3/4 inch deep. Full-depth bituminous expansion joints shall
be placed every 50 feet and at all structures or inlets.
(3)
Gutters shall be broom-finished before the joints
are struck and the finish shall be consistent throughout the project.
(4)
Gutters shall be cured and sealed by spraying with
an approved curing and sealing compound at the rate recommended by
the manufacturer.
(5)
One coat of curing and sealing compound shall be applied
when the work is complete and another coat after the gutters have
set for 48 hours.
(6)
The use of burlap or coverings for curing or protection
is not acceptable until after the concrete has been sprayed and set.
(7)
The gutters, prior to final paving, shall be flooded
and checked for horizontal and vertical line and grade and finish.
If any gutters are found to be constructed in an unacceptable manner
by the Superintendent of Highways, they shall be removed and replaced.

Minimum width shall be five feet or to match existing.
(3)
The base shall be thoroughly compacted crusher-run
stone with a thickness of four inches. The base material shall extend
six inches outside each edge of the concrete sidewalk.
(4)
A cross slope of 1/4 inch per foot shall be maintained
for positive drainage.
(5)
Construction joints shall be wet struck at five-foot
increments and be 3/4 inch deep. Full-depth bituminous expansion joints
shall be placed every 50 feet and at all castings.
(6)
Sidewalks shall be broom-finished and have troweled
edges with a corner radius of 1/4 inch. The finish shall be consistent
throughout the project.

chapter.
C.
Testing.
(1)
The contractor shall obtain in accordance with ASTM
C-31 two samples from every other truck delivering concrete to the
site and have the samples compression tested by an independent testing
laboratory. Trucks transporting more than eight cubic yards shall
require two samples from each delivery to the site.
(2)
Results of these tests shall be submitted to the Superintendent
of Highways.
(3)
The developer shall bear the cost of all testing.
The monuments shall be installed at those locations
shown on the approved final plan and as located in the field by a
licensed land surveyor. They shall be installed to a depth of at least
30 inches below finished grade with the top surface to be flush with
finished grade. Upon the installation of the monuments, the location
shall be certified to the Town by a licensed land surveyor as to their
accuracy.

Editor's Note: See Appendix V, which is included at the end
of this chapter.
A.
Upon satisfactory completion of the utilities and
roads, the entire area within the right-of-way shall be raked and
graded to the approved plans.
B.
The site contractor shall be responsible to fine grade
the edge of road and maintain erosion control. In those areas where
home building has started, cleanup and site maintenance will then
become the responsibility of the builder.
C.
Upon completion of road/gutter installation of a twenty-foot
grass buffer on either side of the road shall be required. This will
help reduce silt runoff into the gutter/storm sewer network.
D.
Debris and spoil banks created during the development
(not home building) of the site shall be entirely removed and/or disposed
of from the site. No burying of debris or material shall be allowed
on approved or proposed building lots.
During the time period between initial installation
and testing and acceptance for dedication, debris and/or sediment
may accumulate in the utility systems. The developer shall be responsible
to flush and remove this debris from the system prior to the final
inspection for dedication.
A.
Street and traffic signs shall be supplied and installed
by the Highway Department in accordance with standards outlined in
the Manual of Uniform Traffic Control Devices (State of New York,
Department of Transportation, Division of Traffic and Safety).
B.
Signs and posts shall be ordered by the Highway Department
for consistency throughout the Town. Upon receipt of signs, they shall
be placed in the field by the Highway Department with sign, post and
installation cost the responsibility of the developer.
