4. Type and Location of Pavement for Tests
4.1 Select sections where traffic is moderate and free-rolling with no grades, curves, intersections, or access points near enough
to cause excessive braking or turning movements, where wear is uniform with full exposure to the sun throughout daylight hours,
and there is good drainage. Select surfaces that are representative of the pavements upon which the fluid traffic marking material
will be used in practice. Such surfaces include portland cement concrete, sheet asphalt, bituminous concrete, rock asphalt, and
bituminous surface treatment.
5. Conditions at Time of Application
5.1 Clean the test area thoroughly of all foreign material. Follow the pavement marking manufacturer’s recommendation for the
application of the pavement marking to be tested. This should include the recommendations for air and pavement temperature,
material temperature, relative humidity, wind chill, and wind speed. Application between 10 a.m. and 3 p.m. is recommended.
During application record air and pavement temperature, wind speed, and relative humidity hourly.
6. Measurement of Wet Film Thickness
6.1 To aid in obtaining the correct film thickness, a The wet film thickness should preliminarily be measured by the applicator
using a comb gauge or other suitable mechanical instrument prior to performing weighted measurements. A length of roofing paper
placed by the side of the road can be used. used and should be as level as possible to maintain a consistent speed of the motorized
striper. Place a rigid metal test panel on the roofing paper and in the path of the test line. A 300 by 300-mm (12 by 12-in.)A 300 mm
by 300 mm (12 in. by 12 in.) metal panel 1.5 mm ( ⁄16 in.) in.) in thickness is satisfactory. Immediately after the test line is applied
by the motorized striper, read the wet film thickness. If the To determine the wet mils thickness by weight, apply a 4 in. test line
across a 12 in. tared metal panel or one of a known weight, and weigh the panel immediately after application using a calibrated
balance of 1500 g capacity with 0.1 g or better sensitivity. The balance should be level and shielded from wind and vibration.
Weighed panels should be quickly cleaned and dried to their original tared weight. If the width, appearance, or wet film thickness
is not satisfactory, adjust the spray pressuremotorized striper and repeat until the target wet film thickness is attained. It is important
that no glass beads or other interfering materials be present that would give a false wet film reading. When the wet film thickness
is correct, apply a test line across a tared metal panel and weigh immediately. A balance must be immediately available and be
thoroughly shielded from wind as well as be of 1500-g capacity with 0.1 g or better sensitivity. As a basis for determination of
glass bead application (The 7.1) the weight of a paint line 100100 mm by 300 mm (4(4 in. by 12 in.) (without consideration for
solvent loss) can be calculated as follows:
W 5 0.0943 ×t ×g
t 5 W⁄~0.0943 × g!
where:
W = weight of paint line, g,
t = mil thickness, and
g = weight per gallon, lb.
6.2 Application of pavement markings by the spray process shall be by an appropriate spray applicator with traction drive and a
spray nozzle similar to that used on normal marking equipment. The machine must be capable of setting and maintaining a constant
speed during the application process. Standard traffic paint shall be applied at a thickness of 15 mil (+ 1 mil).
6.2.1 Application of other materials shall be accordance with the manufacturers’ recommended procedures and as similar as
possible to that used on their normal marking equipment. High build water bourne paints, epoxies, modified epoxies, polyurea,
Methacrylate, and other exotic materials tested shall be applied at the rate recommended by the manufacturer with a 15 mil
minimum. The minimum thickness for thermoplastic material tested shall be 30 mil. If the pavement markings are applied by some
other method than spray, such as extrusion, it must be done with a piece of equipment that will provide consistent material
thickness throughout the test marking and be able to meet the manufacturer’s requirements for the application of the pavement
marking.
6.3 Test line for traffic paint and thermoplastic applied at less than 60 mil in thickness shall be 44 in. 6 ⁄2 in. in width.
Thermoplastic applied at more than 60 mil shall be 66 in. 6 ⁄2 in. in width. For any other materials the applied width shall be
according to the manufacturers’ recommendation.
D713 − 23
6.4 If the material is sprayable and can be applied with traction drive and a spray nozzle similar to that used on normal marking
equipment, thickness shall be checked by weight. For materials applied by any other means the thickness shall be checked by
instrument. Thickness will be determined by use of a test panel and a micrometer or magnetic dry film thickness gauge.
7. Measurement of Glass Beads
7.1 After the completion of 6.1, apply another test line to a tared panel with the motorized striper, this time also adding the glass
beads, and weigh immediately. The weight difference between this measurement and that in 6.1 gives the amount of glass beads
on the panel. Prior to weighing the panel, remove excess glass beads which are not adhered to the pavement marking from the panel
to ensure an accurate representation of the bead rate. The process can be repeated if an adjustment in the bead application rate is
needed. The weight of applied glass beads per gallon of pavement marking material can be calculated as follows:
W 5 1.418 ×B ×~T ⁄ 15!
where:
W = weight of glass beads, g,
B = glass beads per gallon of paint, lb., and
T = thickness of paint being applied, mil.
7.1.1 To calculate the bead rate in terms of weight per unit area use the following calculation:
BeadRate~l b s ⁄ 100 ft !5 ~W ⁄ A!*100
where:
W = weight of glass beads, lb and
A = area of pavement marking, ft .
7.2 Unless a manufacturer has requested to use a special coated bead, glass beads meeting requirements of AASHTO M247 for
Type I Beads (identified at the time of application) will be applied to the pavement markings. The coating on the beads shall be
specified by the purchaser and shall be noted as part of the test report. For standard traffic paint applied at 15 wet mil the glass
beads shall be applied at a rate of 6 pounds per gallon (6 lbs/100 ft ) and will be supplied by the testing agency. The testing agency
will provide quality control test results for the beads provided.
7.3 Use of special beads or other retroreflective optics may be applied at the manufacturer’s recommended application rate and
method. If this is to be done the manufacturer shall provide the recommended application methodology, and application rate in the
form of weight per unit area (such as lb/100 ft ) for each bead or retroreflective optic that is to be used. The manufacturer shall
also provide the technical information for the material being used to include such things as material description, pertinent
specifications met, physical properties such as size, roundness, chemical properties, and coating characteristics. This information
shall be available as part of the report.
7.4 If the bead or reflective optic application can be controlled then the actual bead application rate shall be determined and
included as part of the report. If the rate cannot be consistently controlled then the beads or reflective optics should be applied in
such a manner to fully saturate (flood) the marking and this should be reflected in the report.
8. Application Procedure
8.1 Apply the test stripes at the required width and transversely on the road. At the option of the purchaser, the test stripes may
be applied to the pavement at an angle of 45° to the direction of the traffic, or longitudinally in each wheel path, in order to increase
the area of contact with tr
