                     PAVEMENT MARKING SPECIFICATIONS
ITEM P-620

PAVEMENT MARKING
DESCRIPTION

620-1.1 This item shall consist of preparing the surface and the painting of numbers,
markings and stripes on the surface of runways, and taxiways in accordance with these
specifications and at the locations shown on the drawings, or as directed by the Engineer.



                                             1
MATERIALS

620-2.1 The Contractor shall furnish manufacturer's certified test reports for materials
shipped to the project. The certified test reports shall include a statement that the
materials meet the specification requirements. The reports can be used for material
acceptance or the Engineer may perform verification testing. The reports shall not be
interpreted as a basis for payment. The Contractor shall ship materials in sealed
containers and notify the Engineer upon arrival of a shipment of materials to the site. The
Engineer shall draw 1 quart samples of each batch, including glass beads, directly from
the material guns on the equipment to be used. The samples should be retained for the
warranty period and stored in accordance with manufacturer's recommendations.

620-2.2 Paint shall meet the requirements of Federal Specification TT-P-1952E, Type I,
II, or III. Type II is to be used in environments with high humidity and/or high traffic
where tracking of the paint is a concern. Type III can be used at either standard
application rates, or it can be used as a durable high build coating at different application
rates as specified in Section 620-3.5.

620-2.3 Glass beads shall meet the requirements of Federal Specification TT-B-1325D,
Type I (low index 1.5 IOR), III (high index 1.9 IOR) or Type IV (low index 1.5 IOR -
"big beads"). If Type IV beads are specified, they must be used in conjunction with TT-
P-1952E, Type III that can be applied up to 55 SF/gal. TT-P-1952E, Type I or II should
not be applied under 100 SF/gal.
CONSTRUCTION METHODS

620-3.1 The painting shall be performed only when the surface is dry and when the
surface temperature is above 45 degrees F and rising. A lower temperature based on paint
manufacturer's printed recommendations may be permitted when approved by the
Engineer. Do not paint when wind displaces paint spray or glass beads or when surface is
damp.

620-3.2 All equipment for the work shall be approved by the Engineer and shall include
the apparatus necessary to properly clean the pavement surface, a mechanical marking
machine, and such auxiliary hand-painting equipment as may be necessary to
satisfactorily complete the job.

The mechanical marker shall be an atomizing spray-type or airless-type marking machine
suitable for application of traffic paint, and shall be capable of applying markings from
six inches to three feet wide in a single pass. An even and uniform wet film thickness
from 12-18 mils thick with uniform cross-sections and clear-cut edges shall result from
the marking operation without running or spattering and without over spray. A wind
screen or shroud shall be used on the machine to prevent displacement of materials by
wind.
620-3.3 SURFACE PREPARATION

Immediately before application of the paint, the surface shall be dry and free from dirt,
grease, oil, laitance, rubber, saw cuttings, loose paint, or other foreign material which
would reduce the bond between the paint and the pavement. The area to be painted shall
be cleaned by water blasting, sandblasting or other mechanical means to be followed by
                                              2
vacuuming, sweeping or blowing with compressed air to remove all loose particles. In
areas where existing pavement markings do not conform to the new layout, existing
markings shall be removed in accordance with Item S-190 or per the Engineer's
instructions.

620-3.4 If the existing markings to be repainted are not properly aligned per plans and
specifications, the affected markings shall be laid out as shown on the drawings. Control
points shall be spaced at such intervals as will ensure accurate location of all markings.
The Contractor shall provide an experienced technician to supervise the location,
alignment, layout, dimensions and application of the paint.

620-3.5 Paint shall be applied at the locations and to the dimensions and spacing shown
on the drawings. Paint shall not be applied until the Engineer has approved the layout and
condition of the surface. The paint shall be mixed in accordance with the manufacturer's
instructions and applied to the pavement with a marking machine at the rate of 115
square feet per gallon, producing a uniform film thickness of 15 wet mils. Glass beads
shall be applied at a minimum rate of 7 pounds per gallon of paint for Type I beads or 10
pounds per gallon of paint for Type III beads. If TT-P-1952E, Type III paint is to be
applied at 55 SF per gallon (producing a uniform wet film thickness of 25-30 mils), glass
beads conforming to TT-B-1325D, Type III should be used at a rate of 5 lb. per gallon.
The addition of thinners will not be permitted. A period of time to allow adequate curing
of the pavement surface shall elapse between placement of a bituminous surface course
and application of the permanent paint. This curing period shall be as recommended in
writing by the manufacturer of the paint, generally a minimum of 30 days. Temporary
markings can be applied to new asphalt pavement within the curing period at half
coverage rate (230 SF/gal) without glass beads, both to seal the pavement and to provide
markings for airport operations. The edges of the markings shall not vary from a straight
line more than 1/2 inch in 50 feet, and the dimensions shall be within tolerances as
outlined in the table below.
              Dimension and Spacing Tolerance
              36 inches (910 mm) o r less                         +/- 1/2 inch (12 mm)
              greater than 36 inches to 6 feet (910 mm to 1.85 m) +/- 1 inch (25 mm)
              greater than 6 feet to 60 feet (1.85 m to 18.3 m)   +/- 2 inches (51 mm)
              greater than 60 feet (18.3 m)                       +/- 3 inches (76 mm)

Glass beads shall be distributed upon the marked areas immediately after application of
the paint. A dispenser shall be furnished which is properly designed for attachment to the
marking machine and suitable for dispensing glass beads. Glass beads shall be applied at
the specified rate. Bead dispensers shall be calibrated at the beginning of the project to
the proper flow rate and monitored throughout the course of the project to ensure proper
bead coverage. Retroreflectivity readings shall be taken at the beginning of each day on
markings applied the previous day. With Type I glass beads, readings should be 300-450
millacandelas per square meter per lux for white and 175-250 for yellow. With Type III
glass beads, readings should be 600-1300 for white and 350-550+ for yellow. Type IV
glass beads should have initial readings of 350-500+ for white and 200-350+ for yellow.
All performance criteria for retroreflectivity established herein should be achieved after
twenty-four hours from installation. Glass beads shall adhere to and be properly
embedded in the cured paint or all marking operations shall cease until corrections are
                                                   3
made. A night inspection of the markings is advisable to check for uniform reflectivity of
the markings. All emptied containers shall be returned to the paint storage area for
checking by the Engineer. The containers shall not be removed from the airport or
destroyed until authorized by the Engineer.

620-3.6 DEFECTIVE WORKMANSHIP OR MATERIAL When any material not
conforming to the requirements of the specifications or drawings has been delivered to
the project or incorporated in the work, or any work performed is of inferior quality, such
defective material or work shall be corrected as directed by the Engineer, at the expense

        c. Mult icolored markings must consist of interconnected individual pieces of preformed thermoplastic
   pavement marking material, which through a variety of colo rs and patterns, make up the desired design.
   The individual pieces in each large marking segment (typically more than 20 ft. long) must be fac tory
   assembled with a co mpatib le material and interconnected so that in the field it is not necessary to assemble
   the individual pieces within a marking segment. Obtain ing mult icolored effect by overlaying materials of
   different colors is not acceptable due to resulting inconsistent marking thickness and inconsistent
   application temperature in the marking/substrate interface.
        e. The marking material must set up rapidly, permitting the access route to be re-opened to traffic a
   maximu m o f 15 minutes after application.

       f. The marking material shall have an integral co lor throughout the thickness of the marking material.

   620-2.3 REFLECTIV E MEDIA. Glass beads shall meet the requirements for [ ]. Glass beads shall be
   treated with all co mpatib le coupling agents recommended by the manufacturers of the paint and reflect ive
   med ia to ensure adhesion and embedment.

   *********************************************************
     The Engineer shoul d insert all that will be used in the project. When more than one bead
     type is specified, the plans shoul d indicate the bead type for each marking.

   Federal Specification. TT-B-1325D, Type I, gradation A shall be used when remarking on a frequent basis
   (at least every six months); and should yield at least 300 mcd/m²/lux on white markings at installation and
   at least 175 mcd/m²/lux on yellow markings at installation.

   Federal Specification. TT-B-1325D, Type III, gradation A shall be used when a higher reflective value is
   desired. The high index glass bead, when applied properly, should provide three to four times the longevity
   of the marking than the Type I bead. Initial readings should yield at least 600 mcd/m ²/lux on white
   markings at installation and at least 300 mcd/m²/lux on yellow markings at installation.

   Federal Specification. TT-B-1325D, Type IV, gradation A shall be used with TT-P-1952E, Type III paint.
   The glass beads are larger than either Type I or Type III, thus requiring more of the coating mate rial to
   properly anchor. When applied properly in 25-30 mils wet film thickness (wft) of the high build acrylic
   waterborne material, reflective readings should yield at least 400 mcd/m ²/ lux on white markings at
   installation and at least 225 mdc/m²/lux on yellow markings at installation.

       The Engineer shoul d consult wi th the paint and bead manufacturer on the use of adhesion,
       flow promoting, and/or flotation addi ti ves.

         Due to the increased surface area to cover, the following shoul d be substituted when
         painting P-402 Porous Fricti on Course with waterborne or sol vent based pai nts: "The
         paint shall be mixed in accordance wi th the manufacturer's instructions and applied to
         the pavement wi th a marking machine capable of spraying from two directions
                                                    12
            simultaneously." 50 percent with no glass beads in the first direction, and 100 percent with
            glass beads or sand in the other direction.”

            Markings may be required before pavi ng operations are complete. The Engineer
            may wish to specify waterborne or sol vent-based materials for temporary markings
            at 30 to 50 percent of the s pecified application rates (e.g. rate/0.50 ). No glass beads
            are required for temporary markings. A-A-2886A, Type III may be used for
            temporary markings when reflectorized temporary markings are desired.


            It is recommended when usi ng waterborne paints on previously unmarked asphalt or
            sealcoat, that a primer coat be applied for white markings to reduce the discoloration that
            occurs. The primer coat should be applied at 50% of the permanent coverage rates.
            New concrete pavements should be allowed to cure for eight to twelve weeks before
            removing the curing compound and i nstalling permanent markings.

   ************************************************* ********

Glass beads shall be d istributed upon the marked areas at the locations shown on the plans to receive glass beads
immed iately after applicat ion of the paint. A dispenser shall be furnished that is properly designed for attachment to
the marking machine and suitable for d ispensing glass beads. Glass beads shall be applied at the rate(s) shown in
Table 1. Glass beads shall not be applied to black paint. Glass beads shall adhere to the cured paint or all marking
operations shall cease until corrections are made. Regular monitoring of glass bead embedment should be
performed.


        All empt ied containers shall be returned to the paint storage area for checking by the Engineer. The
        containers shall not be removed fro m the airport or destroyed until authorized by the Engineer.


   *********************************************************

            A 24-to-30 day wai ting period is recommended for all types of paints to be used for
            pavement marking. If the airport operations require pavement marking prior to
            the recommended wai ting period, the paint may be applied in a temporary light coat
            application. Appropri ate modi ficati ons to paragraph 3.5 shoul d be included to
            specify a 30 to 50% application rate for temporary markings. Glass beads are not
            required for temporary markings. The final applicati on shoul d occur after the
            waiti ng period has passed. The fi nal marking applicati on must be at full coverage
            rate in order to adequately set the glass bead. Avoi d s pecifyi ng a 25-33% first
            application and then a 66-75% second application. This approach will not
            adequately set the glass bead.
