E.
The planed surface shall provide a smooth riding surface free from severe gouges,
continuous grooves, ridges, oil film and other imperfections of workmanship and shall have a
uniform surface appearance exclusive of broken or cracked underlying pavement.
All existing pavement around castings shall be removed with hand cold planing equipment or
by the use of hand tools if necessary. Any castings damaged or disturbed shall be
removed and replaced as directed by the Engineer, at the Contractor's expense.
3.06 PAVEMENT PLACEMENT:
A.
3.09
A.
Unless otherwise permitted by the Engineer for particular conditions, only machine
methods of placing the pavement shall be used. The equipment for spreading and finishing
shall be mechanical, self-powered pavers, capable of spreading and finishing the mixture
true to line, grade, width and crown. The mixtures shall be placed and compacted only at
such times as to permit proper inspection and checking by the Engineer.
After the paving mixtures have been properly spread, initial and intermediate compaction
shall be obtained by the use of steel wheel rollers having a weight of not less than 240
pounds per inch width of tread.
Final rolling of the top course or surface treatment pavement shall be performed by a steel
wheel roller weighing not less than 285 pounds per inch width of tread at a mix
temperature and time sufficient to allow for final smoothing of the surface and thorough
compaction.
Immediately after placement of top course or surface treatment pavement, all joints
between the existing and new top course or surface treatment pavements shall be sealed
with hot poured rubberized asphalt sealant meeting the requirements of Federal
Specification SS-S-1401 or SS-S-164.
Where there is no backing for the edges of the curb-to-curb pavement, the Contractor shall
provide a gravel transition. The gravel transition shall be installed immediately after the
pavement is placed, shall be feathered and extend a minimum of 18 inches, and shall be
compacted using the same equipment as for pavement compaction. The gravel shall be
uniformly graded material with a maximum size of 3/8 to 1/2 inch.
When directed by the Engineer, the Contractor shall furnish and install additional paving to
provide satisfactory transition for driveways and walkways impacted by a new curb-to-curb
pavement installation. The transition installation will be considered incidental to the
curb-to-curb pavement installation.
RAISING AND ADJUSTING CASTINGS:
In areas of permanent top course paving, existing municipally-owned catch basin and
manhole castings and valve boxes shall be raised to the proper grade where directed by the
Engineer.
Castings owned by private utilities shall be raised by their own forces. The Contractor
shall be responsible for coordinating this work.
