**Section 559. - WATER PROOFING**

[Delete the text of this section and substitute the
following:]{.underline}

**Description**

+-----------------------------------------------------------------------+
| Use the following SCR for waterproof deck membranes on bridges. Edit  |
| as required. Also include the appropriate SCR for subsection 702.11.  |
|                                                                       |
| Insert the name of the bridge in the space provided.                  |
+-----------------------------------------------------------------------+

**559.01** This work consists of preparing for, furnishing, and placing
a membrane waterproofing system on \_\_\_\_\_\_\_\_\_\_\_\_ bridges.

**Material**

**559.02** Material shall conform to the following subsections:

> Asphalt Cement 702.01
>
> Geotextile, Type VII 714.01(g)
>
> Granulated Rubber 702.11
>
> Pavement Reinforcing Fabric 714.03

**Construction Requirements**

**559.03 General.** At least 14 calendar days before installing the
membrane, submit a proposed procedure for installing the membrane
system. Indicate in detail the techniques, equipment, and materials
proposed for preparing the bridge deck and installing the membrane. Also
indicate what membrane system (i.e. generic according to Subsection
559.06 or proprietary according to Subsection 559.07) is to be used, the
intended dates for installation, traffic control considerations and any
other details necessary to control the work. Do not begin any work on
the bridge deck until the procedure has been accepted. This review and
acceptance shall not relieve the Contractor of the responsibility of
achieving the desired result of a sound waterproof membrane free from
defects.

**559.04 Weather Restrictions.** Do not place tack coats, leveling or
the membrane system during wet, foggy, or frosty weather. Apply the
membrane system to surfaces which are completely clean and dry before
and during application. If the surfaces have been saturated with
moisture before application, dry an additional 24 hours after the
surfaces become visibly dry. Do not apply the membrane system until the
temperature of the prepared deck surface is at least 50°F and the air
temperature in the shade is at least 50°F and rising.

  -----------------------------------------------------------------------
  For new construction, edit 559.05 to remove references to existing
  overlay. Keep last sentence: \"reasonably smooth and clean\" statement.
  On existing bridge decks, include any modifications to paving dams,
  expansion joints, curbs, etc...

  -----------------------------------------------------------------------

**559.05 Preparing the Existing Bridge Deck.** Remove the existing AC
overlay from the bridge deck. Avoid damaging the bridge deck when
removing the existing overlay. Small areas of asphalt and asphalt stain
need not be removed if smooth and tightly bonded to the deck. The deck
surface must be reasonably smooth and clean before applying the new
membrane.

  -----------------------------------------------------------------------
  Eliminate 559.05a if there are not transverse deck joints on the
  bridge. If waterproofing fabric is needed, include SCR for 714.03. If
  not, strike from materials list at beginning of this section.

  -----------------------------------------------------------------------

**(a) Expansion Joints.** Before installing the waterproof membrane,
measure, cut, and install pavement reinforcement fabric over the deck
joint at the pier. Place the fabric such that it is centered over the
deck joint. Install the fabric according to manufacturer\'s
recommendations. Install the fabric full-width of the bridge in a single
piece.

**559.06 Asphalt-Rubber Fabric Seal.** This system consists of a one
course hot asphalt-rubber seal with a geotextile fabric cover.

Provide a self-powered pressure distributor for mixing and spreading the
asphalt and rubber equipped with the following:

> • Separate power pump unit capable of pumping the specified material
> at the specified rate.
>
> • Equipment for heating the bituminous material.
>
> • Distribution bar with nipples and valves bathed in the circulating
> asphalt to the extent the nipples do not become partially plugged with
> congealing asphalt upon standing.
>
> • A tachometer, pressure gauges, volume measuring devices and a
> thermometer for reading temperatures of tank contents.
>
> • Full circulating spray bar controlled by a bootperson riding in such
> a position that all sprays are in full view and readily accessible for
> controlling spread widths.

Before adding the ground rubber, bring the temperature of the asphalt to
between 390°F and 450°F. Combine the asphalt and rubber as rapidly as
possible in the proportions of at least 2 pounds of rubber to 1 gallon
of asphalt (standard at 390°F), then mix until semi-fluid.

Use up to 9% diluent, if needed, to assist in the mixing of the rubber
and the spray application of the mixture. Diluent shall have a boiling
point of at least 350°F.

Apply the mixture as soon as it reaches application consistency. Do not
hold the mixture above 350°F for more than 1 hour after it reaches that
temperature.

Apply the hot asphalt-rubber mixture at the rate of 0.50 (+0.01) gallons
per square yard. Make transverse joints by placing building paper over
the ends of the previous applications, and start the joining application
on the building paper. Once the application process has progressed
beyond the paper, remove and dispose of the paper. Repair any
unsatisfactory joint at no expense to the Government.

Align the fabric and carefully roll or broom it into the asphalt-rubber
mixture. If the alignment of the fabric must be changed, cut the fabric
and realign it overlapping the previous material and proceed as before.

Overlap all joints a minimum of 6 inches. Overlap transverse joints in
the direction of paving to prevent edge pickup by the paver. For lapped
joints, fold the top fabric back and apply a light (0.005 gallons per
square yard) coat of asphalt-rubber mixture. Fold the top fabric onto
the asphalt-rubber mixture, broom and squeegee out smoothly.

Roll or broom the fabric into the asphalt in such a way that any air
bubbles under the fabric are removed. Puncture membrane to release
bubbles or pockets of trapped air or vapor and repair in a manner
satisfactory to the CO.

Apply the waterproof membrane system across the entire width of the
bridges extending it a minimum of 30 inches up the curb faces.

If asphalt sealant bleeds through the fabric, treat the affected areas
with blotter.

**559.07 Proprietary Membrane Systems.** In lieu of the Asphalt-Rubber
Fabric Seal described above, the Contractor may elect to use any of the
following proprietary deck seal systems listed in Table 559-1:

**559.08 Overlay Placement.** Limit traffic on the membrane to necessary
construction equipment and emergency vehicles only. Place a hot asphalt
concrete overlay within 48 hours after placing the membrane.

Do not windrow AC on the membrane ahead of the paving machine. Do not
use an AC pickup machine. Do not turn equipment on the membrane to avoid
membrane movement and damage. Avoid abrupt starts and stops.
