ITEM 417 - COLD PLANING OF BITUMINOUS SURFACES
A. SCOPE

This work shall consist of the removal of existing bituminous pavement between road edges, to
the depth shown on the plans or as ordered by the Engineer. Maximum depth will vary from 2.0”
to 3.5”, depending upon the specific street treatment.

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 be tapered at a rate of 1 FT per inch along longitudinal level changes
and at a rate of 1 FT per 2-inches along transverse level changes. All fillets shall be installed
flush with top of the existing asphalt surface and must be acceptable to the Engineer. The
Contractor shall be responsible for installing, maintaining and replacing all damaged fillets,
where necessary, until the wearing course is placed.

All raised catch basins and manholes shall be spray painted a florescent color around the top of
frames.

Raised structures 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 raised structures
at critical locations.

Fillets and spray painting of castings shall continue as needed or directed by the Engineer until
the top course of pavement is placed and are considered subsidiary to this item.

The Contractor shall prevent any materials from entering drainage structures from this operation
and shall clean out said structures as directed by the Engineer.

All catch basins shall be protected from millings by use of a silt sack. All materials, labor,
equipment, and transportation necessary to install, maintain, and remove the silt sacks and
dispose of collected material shall be subsidiary.

If directed, the Contractor shall furnish all materials, labor, equipment, and transportation

necessary to cut 6” cores to subbase prior to the start of cold planning. Contractor will be
responsible for adequately backfilling holes with hot mix asphalt.
