TECHNICAL SPECIFICATIONS

Technical Specifications 2020 Pavement Preservation

Technical Specifications
A, SCOPE

The work covered by this section of the specification consists of furnishing all materials, labor,
transportation, equipment necessary, and traffic control including flaggers to perform all
operations in connection with the cleaning, sterilizing, removing vegetation, and sealing of
construction and random cracks in bituminous concrete pavements with an approved sealant
material. The Contractor shall furnish all materials, labor, traffic control, equipment, and
transportation necessary for work in accordance with the latest approved City of Nashua
Standard Specification for Road Construction, or the latest approved NHDOT Standard
Specifications for Road and Bridge Construction Section 413 - Hot Poured Crack Sealant. The
most stringent specification shall apply.

B. MATERIAL

Material shall be of the hot-poured type and be a product as included on the NHDOT Qualified
Products List - Hot Poured Crack Sealant, Type II (Item 413.1).

Cc. EQUIPMENT

Equipment used in the performance of the work shall be subject to approval by the Engineer, and
maintained in a satisfactory working condition at all times.

Air Compressor: Air compressors shall be capable of furnishing not less than 100 cubic feet of
air per minute at not less than 90 lbs. per square inch pressure at the nozzle. The compressor
shall be equipped with traps that will maintain the compressed air free of oil and water.

Melting Kettle: Melting kettles shall be of the double-boiler, indirect fired type. The kettle shall
be equipped with a metal shield beneath the firebox to protect the pavement. The space between
the inner and outer shells shall be filled with a suitable heat transfer oil or substitute having a
flash point of not less than 530°F. The kettle shall be equipped with a satisfactory means of
agitating the joint sealer to maintain a uniform temperature. This may be accomplished by
continuous stirring with mechanically operated paddles and/or by a circulating gear pump
attached to the heating unit. Kettles equipped with a rocking type agitation shall not be used, The
kettle shall be equipped with a thermostatic control calibrated between 200°F and 550°F,

Hot-Air Lances: Hot-air lances for blowing clean and drying cracks shall be an approved
propane gas burner and compressed air device that does not allow the flame to touch the
pavement.

BD. CONSTRUCTION

material, and loose edges.

Page I of 3

Technical Specifications 2020 Pavement Preservation

Preparation and Placement of Sealant

The hot-poured sealant shall be maintained in the kettle and applied at the temperature range
specified by the manufacture.

The hot poured sealant shall be applied to the cracks by wand applicator within 2 minutes
following hot-air lance cleaning. The diameter of the applicator shoe is not to exceed 3.5 inches.

All cracks to be treated shall be filled to 1/16” to 1/8” below the pavement surface and have 1.5”
band on either side of the crack with hot-poured sealant with the sealant left slightly concave.
Filling flush, overfilling, and over banding of cracks will not be allowed. Sealant shall tightly
bond to the pavement. The sealant bond to the pavement shall be checked after it had sufficiently
cooled. If the sealant does not bond to the pavement, sealant shall be removed and crack sealing
operations discontinued until debonding problem is corrected.

No hot-air lance cleaning or crack sealing shall be performed when the pavement and cracks are
wet or the ambient temperature is below 50°F.

The contractor must have a full kettle of sealant mixed, heated to the proper application
temperature, and ready for testing at the start of each work day. Once that batch of sealant is
emptied from the kettle, crack sealing operations will cease for the remainder of the day. No
new materials will be allowed to be added to the kettle during the work day under any
circumstances.

The contents of the kettle shall be emptied at the end of each day and shall not be reused.
The sealant shall be allowed to cool sufficiently to prevent lifting, sticking, and tracking prior to

returning the pavement segment to traffic. When traffic requires immediate use of the roadway, a
boiler slag aggregate shall be broadcast over the cracks to prevent the sealant from being picked

up.

All workmanship shall be of the highest quality, and any excess of spilled sealant shall be
removed from the pavement by approved methods and discarded.

E. PERFORMANCE
The contractor must submit the manufacture and product specifications to the Engineer certifying
conformance to this specification and preform a 200 foot test strip in the field prior to the

commencing work under the contract.

Manufacturer’s certificate of material compliance shall be furnished to the Engineer certifying
conformance to the above material specifications.

D. TRAFFIC CONTROL — Flaggers, Uniformed Officer, & Maintenance of Traffic

Traffic control shall be included in the lump sum price per street.
