ITEM 417.20- COLD PLANING TRANSITIONS
A. SCOPE
This work shall consist of the removal of existing bituminous pavement the depth and limits
shown on the plans or as directed by the Engineer. Cold planning transitions are required to tie in
overlays with existing pavement.
For roadways which are being reclaimed this item shall only be used to pay for cold planing at
driveway tie-ins as directed by the Engineer.
For roadways which are being cold planed (milled) prior to overlay, this item shall only be used
to pay for cold planing at driveway tie-ins.
For roadways which are being overlaid without overall cold planing (milling), this item shall be
used to pay for cold planing at driveway transitions and for cold planing transitions to existing
roadway pavement at limits of work as directed by the Engineer.
B. MATERIALS AND CONSTRUCTION
The Contractor shall furnish all materials, labor, equipment, and transportation necessary for
work in accordance with the latest approved City of Nashua Standard Specifications for Road
Construction, or the latest approved NHDOT Standard Specifications for Road and Bridge
Construction. The most stringent specification shall apply.

The material removed from this operation shall remain the property of the City of Nashua and
shall be transported and stock piled by the contractor at the Four Hills Landfill at 830 West
Hollis St in Nashua.
If the road is to be open to traffic after cold planning, level changes shall be tapered by use of
asphalt fillets. Fillets shall extend a minimum of 2’ from level change, and be flush with top of
existing asphalt surface. Fillet construction must be acceptable to the Engineer. Fillets shall be
required until the wearing course is placed and shall be removed before each course of pavement
is installed.
All raised catch basins and manholes shall be spray painted a florescent color around the top of
frames.
Raised structures or driveways greater than 2 inches shall be provided with asphalt fillets until
the wearing course is paved. The Engineer may direct the contractor to install fillets at other
critical locations.
Fillets and spray painting of castings shall continue until the top course of pavement is placed
and are considered subsidiary to this item.
