[HISTORY: Adopted by the Town Board of the Town of Avon 7-14-1966;
amended in its entirety 11-14-1985. Subsequent amendments
noted where applicable.]
These specifications are intended to set forth the minimum standards
for the construction of new public highways in the Town of Avon and shall
be known as the "Standard Road Specifications." The standards set forth herein
may be altered whenever the Town Board, upon recommendation of the Highway
Superintendent, finds that exceptionally heavy travel may be anticipated or
other unusual circumstances exist to warrant such changes.
The contractor shall submit to the Highway Superintendent maps prepared
by a licensed professional engineer, and such maps shall show the right-of-way,
pavement, shoulder and drainage, if any, together with all necessary profiles.
No work shall be commenced until this map has been approved by the Town Board
and any guaranties or other conditions which the Town Board may impose have
been furnished and/or complied with.
The work shall be subject to periodic inspections of the Highway Superintendent
or his duly authorized and qualified representative, and the Highway Superintendent
shall certify to the Town Board that the specifications have been complied
with prior to acceptance of dedication. The Highway Superintendent shall have
full control of the construction of said highway.
A.
No heavy construction equipment for any purpose whatsoever
will be allowed on these roads during construction or thereafter when damage
may be done to the road.
B.
No certificate of occupancy may be issued or any residence
occupied until the road in front of such residence and from such residence
to an already completed road has been constructed in accordance with these
specifications.
[Amended 3-11-1993 by L.L.
No. 1-1993]
The right-of-way for any roadway, except as otherwise specifically provided
in the Town's legislation, shall be a minimum of 60 feet.
The full width of the roadway (pavement and shoulder) shall be 36 feet,
the pavement width being 20 feet and the shoulders on each side being eight
feet, except where the Planning Board, with the approval of the Town Board,
may require a wider pavement. The roadway shall be located in the center of
the right-of-way, unless specifically directed otherwise.
A.
Excavation for the new pavement and base shall be to
the designed subgrade elevation or lower, if necessary, and six inches wider
on each side than the 36 feet specified for pavement and shoulder width. All
necessary fill below subgrade elevation shall be either approved run-of-bank
gravel or select earth approved by the Highway Superintendent or his agent,
placed in layers not exceeding eight inches in thickness in the loose condition,
and each layer shall be compacted with proper equipment to finished subgrade
elevation. Prior to placing any road base, the subgrade shall
be graded to proper subgrade elevation, meaning no earth above and no depression
lower than one inch below true grade and surface, and rolled with a proper
roller. The subgrade shall be crowned 1/4 inch to each foot of width
on each side of the center line. If any unsuitable material is discovered
in the subgrade, the Highway Superintendent or his agent may require that
it shall be excavated, removed from the project and replaced with approved
run-of-bank gravel.
B.
The amount of undercut will be determined by the Highway
Superintendent. The Highway Superintendent may require underdrain pipe in
place of or in addition to such replacement of unsuitable material. This process
of rolling, shaping and filling shall be repeated until no depressions develop.
If the fine grade becomes rutted or displaced due to any cause whatsoever,
it shall be regraded.
The road base will consist of an eighteen-inch gravel foundation. The
gravel shall be placed the full width of the pavement portion and the shoulders.
The gravel foundation portion of the road base shall be constructed
of run-of-bank gravel approved by the Highway Superintendent. Run-of-bank
gravel shall consist of clean, tough, sound, hard stone, free from organic
matter and other deleterious substances. It shall not contain slate, schist,
flat or elongated pieces and shall have a percentage of wear not exceeding
15. When delivered to the construction area, the particles shall be of such
size as will pass through a four-inch square hole and not more than 10% passing
through a 200 mesh sieve and shall be satisfactorily graded and nonplastic.
This gravel foundation will be 18 inches thick when completed and laid in
three courses, two of seven inches and one of four inches thick. Suitable
measuring blocks must be used. Each course shall be thoroughly rolled. This
rolling must begin at the sides and continue towards the center, and the foundation
shall be rolled until the proper compaction is achieved. After rolling, each
course shall be tested with a straight edge 16 feet in length. Any depression
over 1/4 inch in depth shall be satisfactorily rolled and eliminated.
After completion of the rolling, no hauling other than necessary to bring
material for the next course will be allowed over rolled material. These courses
shall not be laid in excess of 500 linear feet without being rolled and thoroughly
filled so as to render them waterproof and thereby prevent softening up of
the subgrade. If the subgrade material shall become churned up or mixed with
either of the courses of gravel foundation through any reason, the contractor
will remove the subgrade material and gravel and replace it with clean gravel.
Drainage will be provided as shown on the maps or as required by the
Highway Superintendent and/or the Town Board.
The surface course will consist of two inches of No. 2 stone compacted
and two one-inch layers of No. 1 stone compacted separately. After the two
inches of No. 2 stone has been thoroughly compacted, a layer of oil shall
be spread at the rate of one gallon per square foot, and immediately after
the oil has been spread, a one-inch layer of No. 1 stone shall be spread and
the stone compacted with a proper roller. Within 24 hours, a second oiling
shall be spread over the roadway and at the same rate per square foot as set
forth herein, and immediately thereafter, a one-inch layer of No. 1 stone
shall be spread and rolled thoroughly.
The right-of-way for any turnaround shall be 100 feet. The paved portion
of the turnaround shall have a radius of 40 feet as measured from the center
of the turnaround, and the entire turnaround shall be paved. In addition,
a six-foot shoulder around the peripheral of the turnaround and contiguous
to the paved portion shall be installed.
Upon compliance with these minimum specifications as set forth herein
or as modified and upon certification of compliance by the Highway Superintendent
of the same to the Town Board, an offer in dedication shall be accepted.
