to the approved plans and to the details shown on the roadway construction
standards drawing.

of public utilities or construction traffic, the replaced roadway
subgrade, base, and surface shall be better than or equal to the original.
(c)
Material excavated from the roadway may be used
as trench backfill, provided that it is free from roots, large stones,
chunks of clay, concrete or asphalt and should be backfilled with
three-fourths-inch quarry process stone.
(d)

stabilized base course, and bituminous concrete surface course shall
conform to the approved plans, to the details shown on the roadway
construction standards drawing, and to the NJDOT Standard Specifications.
(e)
In all cases, the bituminous concrete surface
course material shall extend to the furthest limit of surface damage,
in the construction area, as determined by the Borough Engineer or
his authorized representative, or 1 1/2 times the excavation
width beyond all sides of the trench area, whichever is greater.
(f)
All areas where new surface material shall meet
existing surface material shall be smooth, tight seams.
(2)
Dense graded aggregate.
(a)
Materials. The materials shall be broken stone

(b)
Methods of construction.
[1]
Dense graded aggregate shall not be laid on
the subgrade until the subgrade has been thoroughly inspected by the
Borough Engineer or his duly authorized representative and meets with
his approval.
[2]
The dense graded aggregate base course shall
be rolled to a minimum thickness of four or six inches as specified,
with a power roller weighing not less than 10 tons and a weight on
the rear rolls of not less than 330 pounds per inch of width of roll.
The rolling shall begin at the sides and progress to the center parallel
to the center line of the road.
[3]
The dense graded aggregate base course shall
be placed in a manner which meets the requirements of Section 301
of the NJDOT Standard Specifications.
(3)
Bituminous stabilized base course Type CA-BC.
(b)
Methods of construction.
[1]
The bituminous stabilized base course shall
be spread, in conformance with the cross section shown on the roadway
construction standards drawing, by a bituminous concrete paver which
shall be self-contained, power-propelled, provided with an activated
screed or strike-off assembly. No bituminous concrete material shall
be placed when the atmospheric temperature is below 45° F. or
when the weather is foggy, rainy or otherwise unfavorable unless approved
by the Borough Engineer or his duly authorized representative.
[2]
After the material has been properly spread,
initial compaction shall be obtained by rolling with a three-wheel
power-driven roller having a load of not less than 330 pounds per
inch of width of rear wheel and a total metal weight of not less than
the 10 tons.
[3]
Subsequent rolling shall be done with a two-axle
tandem roller which shall be power driven and shall have a load of
not less than 250 pounds per inch of width of tread of drive roll
and shall have a total metal weight of not less than eight tons.
[4]
Rolling shall begin at the sides and progress
gradually to the center, until the entire surface has been rolled
by the rear wheels. If the width of the base course permits, it shall
be subjected to a diagonal rolling crossing the lines of the first.
Placement of the base course shall be in a manner which meets the
requirements of Section 304 of the NJDOT Standard Specifications.
[5]
Any pavement that becomes loose and broken or
mixed with dirt or is in anyway defective shall be removed and replaced
with new material which shall be immediately compacted to conform
to the surrounding area. Any area showing an excess of bituminous
material shall be removed and replaced.
[6]
When directed by the Borough Engineer or his
duly authorized representative, core samples shall be cut from the
completed pavement and the same forwarded to the Borough Engineer.
The areas of pavement so removed shall be replaced with new material
and refinished. No structure served by said street shall be occupied
during the period between November 15 and March 15 unless the bituminous
stabilized base course has been installed or unless otherwise consented
to by the Borough Council.
(4)
Bituminous concrete surface course.
(a)
Material. Bituminous concrete surface course,
Mix 1-5, materials shall conform to the requirements therefor as specified
in Section 903 of the NJDOT Standard Specifications.
(b)
Methods of construction.
[1]
The bituminous concrete surface course shall
be spread in conformance with the cross section shown on the roadway
construction standards drawing by a bituminous concrete paver which
shall be self-contained, power propelled, provided with an activated
screed or strikeoff assembly. No bituminous concrete material shall
be placed when the atmospheric temperature is below 45° F., or
when the weather is foggy, rainy or otherwise unfavorable, unless
approved by the Borough Engineer or his duly authorized representative.
[2]
After the material has been properly spread,
initial compaction shall be obtained by rolling with a three-wheel
power-driven roller, have a load of not less than 330 pounds per inch
of width of rear wheel and a total metal weight of not less than 10
tons.
[3]
Subsequent rolling shall be done with a two-axle
tandem roller which shall be power driven and shall have a load of
not less than 250 pounds per inch of width of tread of drive roll
and shall have a total metal weight of not less than eight tons.
[4]
Rolling shall begin at the sides and progress
gradually to the center, until the entire surface has been rolled
by the rear wheels. If the width of the surface course permits, it
shall be subjected to a diagonal rolling in two directions, the second
diagonal rolling crossing the lines of the first. Rolling shall be
continued until all roller marks are eliminated and the finished surface
meets the requirements specified in Section 404 of the NJDOT Standard
Specifications.
[5]
Along curbs and at other places not accessible
to the roller, the material shall be thoroughly compacted with hand
or mechanical tampers and hot smoothing irons in a manner which shall
be suitable to the Borough Engineer or his duly authorized representative.
[6]
Any pavement that becomes loose or broken or
mixed with dirt, or is in any way defective, shall be removed and

shall be put as nearly as possible into conditions corresponding to
that which existed prior to construction, all to the satisfaction
of the Borough Engineer or his authorized representative.
Under special and extraordinary circumstances an existing street or roadway may be completely closed to vehicular traffic during construction or reconstruction. Access to existing driveways having ingress and egress to existing public streets or roadways being affected by said improvements shall be maintained at all times.

No roadway or utility construction on any roadways
shall be performed during the winter months between November 15 and
March 15 of any year unless written approval has been obtained from
