CONSTRUCTION METHODS

**605-3.1 TIME OF APPLICATION.**  Joints shall be sealed as soon after
completion of the curing period as feasible and before the pavement is
opened to traffic, including construction equipment.  The pavement
temperature shall be above **\[40**°**F (4**°**C)\]\[(50**°**F
(10**°**C)\]** at the time of installation of the **\[preformed joint
seal\]\[poured joint sealing material\].**

\* \* \* \* \* \* \* \* \* \* \* \* \* \***

> **Specify 40°F (4°C) for preformed seal and 50°F (10°C) for poured
> seals.**
>
> **If the pavement must be opened to traffic prior to placement of the
> sealant, this paragraph should be modified to require the Contractor
> to temporarily fill the joint with a jute or nylon rope immediately
> after the joint is sawed.  The rope should be slightly larger than the
> joint and should be forced into the joint so that the top of the rope
> is 1/8 inch (3 mm) below the pavement surface.  The rope shall be
> removed immediately prior to cleaning.**

**605-3.2 PREPARATION OF JOINTS.** 

**a. Sawing**. All joints shall be sawed in accordance with
specifications and plan details. Immediately after sawing the joint, the
resulting slurry shall be completely removed from joint and adjacent
area by flushing with a jet of water, and by use of other tools as
necessary.

**b. Sealing**. Immediately before sealing, the joints shall be
thoroughly cleaned of all remaining laitance, curing compound, and other
foreign material. Cleaning shall be accomplished by sandblasting.
Sandblasting shall be accomplished in a minimum of two passes. One pass
per joint face with the nozzle held at an angle directly toward the
joint face and not more that 3 inches from it. Upon completion of
cleaning, the joints shall be blown out with compressed air free of oil
and water. Only air compressors with operable oil and water traps shall
be used to prepare the joints for sealing. The joint faces shall be
surface dry when the seal is applied.

**605-3.3 INSTALLATION OF SEALANTS.**  Joints shall be inspected for
proper width, depth, alignment, and preparation, and shall be approved
by the Engineer before sealing is allowed.  Sealants shall be installed
in accordance with the following requirements:

**\[Hot Poured Sealants.  The joint sealant shall be applied uniformly
solid from bottom to top and shall be filled without formation of
entrapped air or voids.  A backing material shall be placed as shown on
the plans and shall be nonadhesive to the concrete or the sealant
material.  The heating kettle shall be an indirect heating type,
constructed as a double boiler.  A positive temperature control and
mechanical agitation shall be provided.  The sealant shall not be heated
to more than 20**°**F (‑11**°**C) below the safe heating temperature.
The safe heating temperature can be obtained from the manufacturer\'s
shipping container.  A direct connecting pressure type extruding device
with nozzles shaped for insertion into the joint shall be provided.  Any
sealant spilled on the surface of the pavement, structures and/or
lighting fixtures, shall be removed immediately.\]**

**\[Cold Applied Sealants.  Cold applied joint sealing compound shall be
applied by means of pressure equipment that will force the sealing
material to the bottom of the joint and completely fill the joint
without spilling the material on the surface of the pavement.  A backing
material shall be placed as shown on the plans and shall be nonadhesive
to the concrete or the sealant material.  Sealant that does not bond to
the concrete surface of the joint walls, contains voids, or fails to set
to a tack‑free condition will be rejected and replaced by the Contractor
at no additional cost.  Before sealing the joints, the Contractor shall
demonstrate that the equipment and procedures for preparing, mixing, and
placing the sealant will produce a satisfactory joint seal.  This shall
include the preparation of two small batches and the application of the
resulting material. Any sealant spilled on the surface of the pavement,
structures and/or lighting fixtures, shall be removed immediately.\]**

> **The use of a backup material or bond breaker in the bottom of the
> joint to be filled is recommended to control the depth of the sealant,
> to achieve the desired shape factor, and to support the sealant
> against indentation and sag.  Backup materials and bond breakers
> should be compatible with the sealant, should not adhere to the
> sealant, should be compressible without extruding the sealant, and
> should recover to maintain contact with the joint faces when the joint
> is open.**
>
> **Jute, paper, or other moisture absorbing material shall not be used
> for the backing material. The backing material shall be rubber, butyl
> rubber, or other approved material that will not react with the joint
> sealer and will not form a gas when the hot joint sealer is applied.**
