[Adopted 4-24-1962 by Ord. No. 380]
All curbs in the Borough shall be constructed strictly in accordance
with the specifications hereinafter set forth.
A.
Dimensions. Unless otherwise specified, concrete curbs shall be constructed
in accordance with the "Typical Curb Section for Municipal Roads"
herein shown as Figure 1.[1] The approximate dimensions are: depth, 18 inches; top
width, six inches; width at 1/2 depth, nine inches; and bottom width,
nine inches. The batter on the front face shall be three inches in
nine inches and the rear face shall be vertical. The top face of the
curb shall be velled or sloped at the rate of 1/4 inch per foot, and
the radius of the outside edge shall be one inch.
[1]
Editor's Note: Figure 1 is on file in the Borough offices.
B.
Forms.
(1)
The forms used may be of metal, or of thoroughly seasoned and dressed
lumber, not less than two inches in thickness. Forms must be placed
in proper alignment and thoroughly staked and braced. Before any concrete
is deposited, the forms shall be clean and free from dirt and thoroughly
oiled. Forms which have become bent or warped, and which in the opinion
of the Borough Engineer are unsuitable for use, will be rejected and
shall be removed from the site of the work.
(2)
Forms for radius curb may be of metal or, if constructed of wood,
shall be not more than 1/2 inch in thickness, dressed and thoroughly
battered together. They shall be so set to give the same batter of
the street face as straight curb.
C.
Body of curbs. Concrete for curbs shall be Class B air-entrained
portland cement concrete, in accordance with the 1961 New Jersey State
Highway Department Standard Specifications, except that the stone
shall be 3/4 inch. As the concrete is placed into the forms, it shall
be thoroughly tamped and compacted or vibrated to insure that it completely
fills the forms and that all stone is completely imbedded in the mortar.
After the concrete has sufficient set and strength, the outside edge
of the curb shall be properly rounded with a curb-edging tool having
a radius of one inch. The face of the forms shall be removed and the
outside faces of the curb rubbed and finished with a steel float.
Plastering will not be permitted, and the use of gravel in any form
is absolutely prohibited.
[Amended 10-24-1967 by Ord. No. 439]
D.
Joints. The curb shall be constructed in sections 10 feet long. Each
section is to be separated by a three-sixteenths-inch metal form plate
or other accepted material having the approval of the Borough Engineer.
The plates shall extend through the whole thickness and depth of the
curb. The plates shall act as spacing plates to the forms, and the
joints so formed will serve to take up expansion and contraction.
E.
Driveway openings. Where required, driveway openings shall be provided
by lowering or depressing the top of the curb five inches below normal
elevation across the entire width of the driveway. Care is to be taken
to provide a neat and attractive transition from the normal curb height
to the depressed curb height.
[Amended 10-24-1967 by Ord. No. 439]
All sidewalks in the Borough shall be constructed strictly in
accordance with the specifications hereinafter set forth.
A.
Excavation. The subgrade shall be prepared and properly tamped to
a depth of eight inches below finished grade of the sidewalk.
C.
Forms. Sidewalk forms may be of metal or wood and, if of wood, shall
be not less than two inches by four inches and free from warps or
bends. All forms must be thoroughly braced and staked to the established
lines and grades.
D.
Foundation. Upon the subgrade shall be placed a layer of clean sand
having a compacted thickness of four inches.
E.
Body of sidewalk. Concrete for sidewalks shall be Class C air-entrained
portland cement concrete in accordance with the 1961 New Jersey State
Highway Department Standard Specifications, except that the stone
shall be 3/4 inch. Concrete shall be placed in the forms and on the
prepared foundation to a thickness of four inches, minimum. After
being placed, the concrete shall be tamped, screened and finished
to true grade and even surface. Care is to be taken to insure that
the concrete completely fills the forms and that all stone is completely
imbedded in the mortar. After the concrete has sufficiently set, the
finish shall be applied with a wooden float so that a slightly roughened
surface is obtained. The surface shall then be brushed with a wet
soft-haired brush to obtain a neat surface. Expansion joints 3/16
inch wide shall be provided every five feet, and the joints filled
with sand. All exposed edges of the sidewalk and joints shall be rounded
with a sidewalk-edging tool having a radius of 1/2 inch.
[Amended 10-24-1967 by Ord. No. 439]
F.
Sidewalks at driveways and concrete aprons. Across driveways and
wherever directed by the Borough Engineer, the thickness of the concrete
for the sidewalk shall be six inches, and the sidewalk constructed
in the manner outlined above. Between the sidewalk and the curb, a
concrete apron shall be constructed. This apron shall have a uniform
slope from the grade of the sidewalk to the top of the depressed curb.
This apron shall be constructed in the manner as outlined above for
a concrete sidewalk, except the concrete shall be five inches thick
and no sand shall be placed under the apron.
All streets in the Borough shall be constructed strictly in
accordance with the specifications hereinafter set forth:
B.
Formation of subgrade.
(1)
The surface upon which the pavement is to be placed shall be known
as a subgrade and must conform to the lines and grades and cross sections
given.
(2)
After all drains have been laid, and all frames and heads of manholes,
catch basins and other structures have been reset at proper grade,
and subgrade has been shaped correctly, it shall be brought to a firm
unyielding surface by rolling the entire area with a three-wheel,
ten-ton power roller. Any portions of the subgrade which are not accessible
to the roller shall be thoroughly compacted with hand tampers weighing
not less than 50 pounds, the face of which shall not exceed 100 square
inches. All places in the subgrade which do not attain the required
stability or compact properly when rolled shall be excavated and replaced
with suitable material.
(3)
No base or surface material shall be dumped or deposited on a subgrade
that has not the required stability, is not at the proper grade, or
does not have the specified cross section. The subgrade shall not
be disturbed by any unnecessary carting or hauling upon it, but if
the surface is disturbed, the same shall be reshaped and rerolled
before the spreading of any foundation material. Projections or high
places shall be reduced and all depressions filled, and filling and
rolling shall continue until the subgrade has a uniform, even surface
at the required grade and crown and has the required density and solidity
at all points. Should the existing subbase material be judged unstable,
or in any way not acceptable, by the Borough Engineer, this material
shall be excavated to a depth that the Engineer shall deem necessary
and replaced with an acceptable subbase material, and the subgrade
formed as outlined above.
C.
Macadam foundation.
(1)
After the subgrade has been properly prepared as herein specified,
two-and-one-half-inch stone shall be deposited thereon in a uniform
layer having a depth when compacted of four inches unless otherwise
shown on plans. When ordered by the Engineer, the thickness of the
loose stone shall be measured by wooden blocks of the required depth.
No stone shall be placed upon a wet subgrade.
(2)
As soon as the stone has been properly spread, it shall be rolled
with a three-wheel power roller, weighing not less than 10 tons, until
thoroughly consolidated and compacted to a smooth, even surface. During
the initial rolling, the roller shall travel parallel to the axis
of the pavement, beginning at each edge and working toward the center.
The subsequent rolling shall be both diagonal and parallel to the
axis of the pavement, so that every part of the stone surface receives
compression from the rear wheels of the roller.
(3)
After the stone has been properly rolled, screenings shall be spread
in layers not over 1/2 inch in thickness and worked into the voids
thereof with intermittent rolling between each application until all
voids have been filled and the stone ceases to creep or sink under
the roller and is at the proper grade. Before and until the surface
pavement is applied on this foundation, it must be firmly bound together,
be at the proper grade, have the required crown, and be free from
ruts, loose stone, places showing instability and stone covered with
sufficient binder as to hide the top faces and edges.
(4)
If at any time during the construction of the foundation the subgrade
shows evidence of instability, is forced below grade or up into the
voids of the stone, the contractor shall dig out all such loose or
unstable material, reshape and repack the subgrade in the manner ordered
by the Engineer, and shall replace the stone removed with the necessary
additional stone, which, when bound and rolled as herein specified,
shall give the required stability.
D.
Modified penetration macadam intermediate course.
(1)
After the foundation course has been prepared as herein specified,
a uniform layer of one-and-one-half-inch stone shall be spread over
its surface to a depth of two inches compacted.
(2)
As soon as the stone has been properly spread, it shall be rolled
with a three-wheel power roller, weighing not less than 10 tons, until
thoroughly consolidated and compacted to a smooth, even surface. Additional
three-quarter-inch stone shall be added when, in the opinion of the
Engineer, the interstices would require too much bitumen to properly
fill, and the rolling continued until the surface is thoroughly compacted.
During the initial rolling, the roller shall travel parallel to the
axis of the pavement, beginning at each edge and working toward the
center. The subsequent rolling shall be both diagonal and parallel
to the axis of the pavement, so that every part of the stone surface
receives compression from the rear wheels of the roller.
E.
Application of bitumen.
(1)
Bituminous binder Grade OA-4 or NA-4 shall then be applied at the
rate of 1.65 to 1.75 gallons per square yard or surface, applied from
an approved pressure distributor, which must be equipped with stationary
Fahrenheit thermometers for accurately indicating temperatures of
bitumen. No bitumen shall be applied when the atmospheric temperature
is below 50° F. or has been below 40° F. within the preceding
eight hours.
(2)
When bituminous binder is applied, it must have a temperature between
300° F. and 350° F.
(3)
While the bitumen is still warm, a uniform layer of five-eighths-inch
stone shall be spread in sufficient quantity to fill the voids. The
stone shall be taken from piles adjacent to the road deposited there
before the bitumen is spread. The road surface shall be rolled until
the stone is thoroughly imbedded in the bitumen and anchored in place.
If bitumen appears on the surface in such quantity as to stick to
the wheels of the roller, additional stone must be applied at such
points. The rolling shall be continued until the surface is firmly
bound together, hard and smooth, and shows no perceptible movement
under the roller.
F.
Bituminous concrete surface course: hot mix. After the modified penetration
macadam intermediate course has been constructed, there shall be placed
upon it a bituminous concrete surface course 1 1/2 inches thick
when compacted. The top course shall consist of hot mix bituminous
concrete, New Jersey State Highway Specifications, Type FA-BC-1 or
Type S.M.1. The top course shall be constructed in accordance with
the 1961 New Jersey State Highway Department standard specifications.
Any person who shall construct, remove, repair, replace, reset
or alter the curb, sidewalk or street or cause the construction, removal,
repair, replacement or altering of the curb, sidewalk or street shall
do so strictly in accordance with the above specifications and under
the supervision and inspection of the Borough Engineer and shall pay
such reasonable fee for said inspection as may be required.
A person violating any of the provisions of this article shall,
upon conviction, be subject to a fine not to exceed the sum of $100
and, upon default in the payment of said fine, may be imprisoned in
the county jail for a term not to exceed 30 days. Every day that such
violation continues shall be deemed to be a separate offense.
All ordinances or parts of ordinances inconsistent herewith
are hereby repealed.
This article shall take effect immediately after passage and
publication as required by law.
