It is the intent of this chapter to exercise
exclusive jurisdiction by the Township over all driveways into Township
streets; to exercise concurrent jurisdiction with the County of Warren
and the State of New Jersey Department of Transportation with respect
to the portion of any driveway located within the jurisdiction limits
of a county or state street or highway and to further exercise exclusive
jurisdiction over those portions or driveways beyond the jurisdiction
limits of those agencies. Therefore, all references contained herein
to "Township road" or "public road" shall be construed to mean Township,
county or state street or highway.
The geometric design of a driveway connection
to a Township road shall be governed by sound traffic engineering
principles. Below are guidelines in preparing a geometric design,
but deviation from them may be necessitated due to the many variables
encountered in the course of preparing a design. The applicant should
be aware, therefore, that although the driveway layout may conform
to these guidelines, conditions may dictate deviations from them and
requirements of the Township Engineer shall be final.
A. Two-way operation. Driveways used for two-way operation
shall intersect the Township road at an angle as near to 90° as
site conditions will permit, and in no case shall be less than 75°.
B. One-way operation. Driveways used by vehicles in one
direction of travel, right turn only, shall not form an angle smaller
than 45° with a Township road.
C. Dimensions.
(1) The dimensions of driveways shall be designated to
adequately accommodate the volume and character of vehicles anticipated
to be attracted daily onto the land development for which a site plan
is prepared. The required maximum and minimum dimensions for driveways
connecting to a Township road at 90° are indicated below. Driveways
serving large volumes of daily traffic or traffic over 25% of which
is truck traffic shall be required to utilize high-to-maximum dimensions.
Driveways serving low daily traffic volumes or traffic less than 25%
of which is truck traffic shall be permitted to use low-to-minimum
dimensions.

(2) Driveways connecting to a Township road at an angle
shall have the same widths as shown in the tables above. The width
of depressed curb and the radius of curb returns shall provide for
the sharpest turning radii of vehicles using the driveway, keeping
the vehicles within their prescribed lanes.
D. Vertical curves and alignment.
(1) Vertical curves. Any vertical curve on a driveway
shall be flat enough to prevent the dragging of any vehicle undercarriage.
The maximum permitted gradients for driveways are shown in the following
subsection. The profile dimensions given beyond the sidewalk are maximum
for grades and minimum for grades and minimum for grade lengths.
(2) Vertical alignment.
(a)
Residential.
[1]
First five feet: plus 12%.
[2]
Second five feet: plus 2%.
[3]
Then as a maximum, plus or minus 15%.
(b)
Commercial and multifamily residential. Not
greater than 4% within 100 feet of the curbline, with a maximum of
6% at any other location.
E. Regulations for steep ramps. Should the sidewalk be
so close to the curb at a depressed curb driveway as to cause the
ramp to be too steep and is likely to cause undercarriage drag, the
sidewalk shall be appropriately lowered to provide a suitable ramp
gradient.
F. Future curb or gutter line. Driveways shall be designed and constructed such that the vertical alignment requirements shall begin at the future curb or gutter line of any municipal roadway. The classification of the roadway shall be determined from the current Mansfield Township Master Plan and the width and cross-section requirements as set forth in Article
XI, Streets, of Chapter
361, Design and Performance Standards, of the Township Code. The area between the existing roadway and the future curb or gutter line shall be paved and graded in accordance with the paving provisions of this chapter.
G. Bridges or culverts over four feet diameter. All bridges
or culverts in excess of four feet in diameter (or equivalent) shall
be designed in accordance with current AASHTO bridge practice to accommodate
an H20 design vehicle.

NOTE 1: The use of reclaimed asphalt pavement
(RAP) also commonly known as "millings" may be substituted for the
pavement requirements of Class I and II driveways outside of the right-of-way,
subject to the following provisions:
|
1.
|
The material shall conform to NJDOT Standard
Specifications for Road and Bridge Construction (2001), hereafter
referred to as "NJDOT Standard Specifications Article 901.10(B)," and shall further contain
no foreign matter. The source of the millings shall be from milled
pavements where a portion of a surface course or base course has been
removed and no portion of the milled area shall have been outside
an existing pavement structure. This shall mean that the millings
shall be from what is commonly known as "main line pavements" and
shall not have as a source any millings from trench removal or complete
pavement removal.
|
2.
|
The depth of the millings shall be no less than
eight inches.
|
3.
|
The millings shall be placed when the ground
and air temperatures are above 70° and expected to remain so for
several days. No millings shall be placed later than September 30.
|
4.
|
The millings shall be placed by a convenient
method and shall be rolled with a roller conforming to the requirements
of NJDOT Standard Specifications Section 404.09. Any driveway which
utilizes millings as a substitute pavement shall be classified as
a Class II driveway without regard to the grade or other characteristics.
All millings shall be covered with wither a hot mixed asphalt (HMA)
pavement course or shall receive a binder complying with the requirements
of NJDOT Standard Section 404.15.
|
5.
|
All millings installation shall be in accord
with the New Jersey Department of Environmental Protection (NJDEP)
document entitled "Asphalt Millings Guidance Document," revised to
5/15/2002 or more current date.
|
