subgrade shall be in a properly finished condition conforming to the
proper line and grade and free of any soft spots or other deficiencies.
Not more than 24 hours prior to commencing of operations on any subgrade,
the subgrade shall be tested by running a roller of a weight at least
equal to that to be used in the paving operation over the entire subgrade
area. When permitted by the Engineer, testing may be performed by
other equipment, such as loaded trucks. When in the opinion of the
Engineer or his representative the deformation of the subgrade under
such test is excessive, the subdivider will be required to stabilize
the subgrade in a manner satisfactory to the Engineer. The subgrade
shall not be prepared during freezing weather or when frozen or when
it is unstable due to excessive moisture.[1]

(2)
Bituminous-stabilized base course.
[Amended 12-17-1973 by Ord. No. 1973-18]
(a)
The method of construction shall conform to
the same specification indicated for materials above.
(b)
The base course shall be laid on a properly
prepared subgrade and shall consist of two equal courses.
(c)
Upon completion of base-course construction,
the contractor shall cut samples from the pavement with a jack hammer,
coring machine or other means suitable to the Engineer. The sample
shall be intact for the full thickness of the base course and shall
be of a size suitable to the Engineer. At least one sample shall be
cut for every 1,000 square yards of base course. Where deficiencies
in the required minimum thickness are noted, at least two additional
cores will be required to determine the extent of such deficiency.
The average thickness of the base course as determined by any five
or more samples, representing contiguous areas of pavement, shall
be not less than five inches or six inches, and the minimum thickness
permitted at any location will be 4 1/2 inches or 5 1/2
inches. In the event that the average thickness is less than five
inches or six inches or the minimum thickness 4 1/2 inches or
5 1/2 inches, the deficiency shall be made up by increasing the
thickness of the surface course.
(d)
All man holes and water valve boxes shall be
set even with the stabilized base course.

Surface course.
[Amended 12-17-1973 by Ord. No. 1973-18]
(a)
Prior to placing of the surface course, the
contractor shall repair any defects in the base course. Where cracking
or any other type of failure has occurred in the base course, the
contractor shall completely remove the base course, stabilize the
subgrade, if necessary, and construct a new base course. Where the
deficiency involves depressions or raveling in the surface of the
base course, the repair may be made by skin patching with a suitable
bituminous material. For checking of gutter drainage, the subdivider
shall supply sufficient water at the high points of the streets and
shall run said water into the gutters in order to determine whether
or not gutter grades are satisfactory. Wherever puddles occur, he
shall skin patch the base course to achieve proper grades in the gutters.
After repair of the base course, a tack coat shall be applied as specified
in Section 3.10 of the New Jersey State Highway Department Standard
Specifications.
(b)
In the event of any deficiency in the surface
course, such as raveling, depressions, cracking, etc., such deficiencies
shall be repaired by removing the surface course and replacing with
new material.
(c)
All equipment and methods of construction shall
conform to the New Jersey State Highway Department Standard Specifications
of 1961, except that only one roller may be used where the area to
be paved is sufficiently small, in the opinion of the Engineer, to
make the second roller unnecessary.

to prevent water from running in. The contractor shall remove any
water accumulating in excavations by pumping or other suitable means.
(4)
The contractor shall do all bracing, shoring and sheeting
necessary to prevent failure of the banks of the excavation and to
protect the work, workmen, public, under- and aboveground utilities
and structures, pavements and public and private property. No bracing,
shoring or sheeting shall be placed below the bottom of the pipe or
structure unless approved by the Engineer.
(5)
