This Article shall be known and may be cited
as the "Road Improvement Ordinance of the Township of Bethlehem."
[Amended 12-10-1971 by Ord. No. 132]
The purpose of this Article shall be to apply
rules, regulations and standards regulating the improvements required
prior to the acceptance of roads into the municipal road system of
the Township of Bethlehem, be the same new roads hereafter created
or be the same existing roads or rights-of-way presently used but
not accepted into the municipal road system of the Township of Bethlehem
and not heretofore accepted for full municipal maintenance. In addition,
the purpose of this Article shall be to apply rules, regulations and
standards regulating the improvement of roads not to be accepted into
the municipal road system of the Township of Bethlehem but created
by provision of the Zoning and Subdivision Ordinances of the Township
of Bethlehem and after completion thereof, constituting private roads.
Subsequent to the adoption of this Article,
all roads shall comply with the following standards of construction
before the same are accepted into the municipal road system of the
Township of Bethlehem and accepted for full municipal maintenance.
As used in this Article, the following terms
shall have the meanings indicated:
PLAN
The road improvement plan approved by the Planning Board
of Bethlehem Township where a new road or an improvement of an existing
road is required by virtue of a subdivision, or a road improvement
plan approved by the Township Engineer in the case of an existing
road being improved to township standards for the purpose of acceptance
into the township road system for full municipal maintenance.
STANDARD SPECIFICATIONS
Those applicable specifications set forth in Standard Specifications
for Road and Bridge Construction, 1961, New Jersey State Highway Department.
Where required by the plan, curbs shall be of
portland cement construction or Belgian block construction as follows:
A. Portland cement construction.
(1) Materials. Concrete shall be Class B as specified
in Article 4.1.2 of the Standard Specifications and shall be air-entrained.
(a)
Joint filler of the preformed bituminous cellular
type shall conform to the requirements specified therefor in Article
8.5.31 of the Standard Specifications.

and backfilling, shall be well compacted by means of flat-faced mechanical
tampers or by other means approved by the Township Engineer.
(3) Driveways and entrances. Curbs at driveways and entrances
shall be depressed so that the top is two inches above the adjacent
pavement or shoulder surface. The width of opening shall be approved
by the Township Engineer, and in no case shall a single opening be
wider than 20 feet for a residence or 40 feet for other uses.
(4) Preparation and placing. Preparation of the concrete
shall be as specified in Article 3.12.3 of the Standard Specifications,
except that the consistency shall be as specified in Article 4.1.3
of the Standard Specifications.
(a)
Wood or metal forms may be used and shall be
constructed to conform to the lines and grades established by the
plan, as approved, except that minor grade and line adjustments shall
be permitted in the field with the prior approval of the Township
Engineer. The materials and methods used for lubricating the forms
shall be such that will not discolor or stain the concrete. Forms
shall be removed when the concrete has hardened sufficiently to be
self-supporting yet in ample time to allow for finishing as hereinafter
specified.
(b)
The concrete shall be tamped and spaded or vibrated
so that the forms are completely filled, the concrete is thoroughly
compacted and mortar is flushed to the face and top. The top and face
shall be finished with a wood float to an even, smooth and dense surface
to form a neat and workmanlike appearance.
(5) Joints. Expansion joints shall be provided at approximate
equal distances of not more than 20 feet and shall be filled with
preformed bituminous cellular type joint filler, 1/4 inch thick, which
shall be inset 1/4 inch from the top and face. Curb joints shall be
neatly rounded to a one-fourth-inch radius.
(6) Curing. Concrete curbs shall be cured with clear or translucent liquid compound which shall be applied as soon as the concrete has been finished. The rate of application and workmanship shall in all ways agree with §
136-10G of this Article.
(7) Existing curbing. Gradual transitions shall be constructed
where changes in the size or shape of curbs occur in a continuous
section.
(8) Measurements. All curbs shall be constructed and located
as shown on the Construction Detail for Concrete Curbs.
B. Belgian block construction.
(1) Belgian (granite) block curb shall be constructed
to the lines and grades shown on the plan, and the dimensions shown
on the detail shall govern. Granite blocks shall be of uniform quality,
structure and texture and with a percentage of wear of not more than
4.5%. The blocks shall be dressed so that all faces are approximately
rectangular and so that the blocks can be set with the greatest dimension
vertical, with joints not more than 1/4-inch wide. The dimension of
the blocks shall be as follows:
Dimension
|
Not Less Than
(inches)

(2) The blocks shall be all from one quarry and of the
same color and texture. All edges shall be parallel with and at right
angles to each other.
(3) Setting Belgian block curb. The granite blocks shall
be set with the greatest dimension vertical, the next greatest dimension
parallel with the line of the curb and the least dimension perpendicular
to the line of the curb. The blocks shall be set in concrete, Class
C of the Department of Transportation specifications. When the blocks
are in final position, the dimensions for the Class C concrete shown
on the detail shall govern. The bottom of the trench shall be excavated
to such a depth as will provide not fewer than eight inches of concrete
under the longest block. All curbing shall be set accurately to line
and grade and shall present an even, unbroken line for the entire
length of the work. Where shown on the plan or where directed by the
Township Engineer, the curb shall be lowered to within two inches
of the surface of the roadway pavement (gutter) to provide for driveways
and entrances. When set in final position, the curb shall have a uniform
batter of one inch per foot. Within five feet of each inlet, blocks
of at least 12 inches in height shall be used to conform to the eight-inch
curb piece of the inlet casting. Articles 5.5.3 and 8.5.28 of the
Standard Specifications for Roads and Bridge Construction, 1961, shall
govern this work and these materials unless specifically altered by
the subsections above.
Where required by the plan, the following specifications
shall be applicable:
A. Materials. All sidewalk construction shall be of portland
cement concrete. Concrete shall be Class C, as specified in Article
4.1.2 of the Standard Specifications, and shall be air-entrained.
The materials for concrete and the materials and methods used for
air entrainment shall be as specified in Article 3.12.2 of the aforementioned
Standard Specifications and preformed bituminous cellular type and
preformed bituminous-type joint fillers shall conform to the requirements
specified respectively therefor in Article 8.5.31 of the same aforementioned
Standard Specifications.
B. Subgrade. The subgrade for all sidewalks shall be
constructed smooth and even and at the prescribed grade. It shall

and four inches thick and shall be located and constructed as shown
on the Construction Detail for Concrete Sidewalks. All sidewalks at
driveways shall be at least six inches thick.
E. Concrete work. Preparation of the concrete shall be
as specified in Article 3.12.3 of the Standard Specifications. After
being placed, the concrete shall be tamped, screeded and finished
to true grade and surface. The finish shall be made with a wood float,
followed by brushing with a wet soft-hair brush to a neat and workmanlike
surface.
F. Joints. Transverse expansion joints, 1/2 inch wide,
shall be provided at intervals of not more than 16 feet and filled
with preformed bituminous cellular-type joint filler. Longitudinal
points, 1/4 inch wide, shall be provided between curbs and abutting
sidewalks and shall be filled with preformed bituminous-type joint
filler. The top of all joint filler material shall be 1/4 inch below
the top of the sidewalk. Transverse surface grooves shall be cut into
the sidewalk surface between expansion joints at intervals equal to
the sidewalk width. All edges shall be neatly rounded with a one-fourth-inch
radius.
G. Curing. Sidewalks shall be cured with clear or translucent
liquid compound which shall be applied as soon as the concrete has
been finished. The compound shall be applied in one application at
a rate of one gallon per 200 square feet of surface and in a continuous
uniform film. If the film becomes damaged in any way, the contractor
shall apply a new coat of material to the affected areas equal in
curing value to that specified for the original coat. The treated
surface shall be protected from all vehicular and pedestrian traffic
for a period of at least three days.
H. Finishing. Sidewalks shall be finished with a slightly
roughened surface using a wood float or broomed with a hair broom.
