The marking compound shall contain glass beads and shall have a top dressing of glass beads applied. The t hermoplastic material shall be capable of bearing traffic within 5 minutes after application and show no deformation or flaking at temperatures between – 23 °C to 60 ° C (–10 °F to 140 ° F). (

omposition. The thermoplastic material shall conform to AASHTO M249 with the exception of the relevant differences due to the material being preformed, and the following specifications. The preformed thermoplastic pavement markings shall consist of a homogeneous mixture of resins, fillers, pigments, and glass beads. The resin shall be the alkyd type thermoplastic composed of a modified ester rosin. The i nfrared spectra of the extracted resin will be compared to the characteristic absorption bands of maleic modified glycerol ester of rosin. 2.G lass Beads. The markings shall contain a minimum of 30% glass spheres which shall conform to AASHTO M247, Type 1, except that glass spheres shall have a minimum of 70% true spheres on each sieve and 80%true spheres overall. 601

securely bonded protruding exposed layer of beads that provide immediate retroreflectivity. No additional glass beads shall be needed to be dropped on the material during application to obtain the necessary retroreflectivity.

retroreflectivity. At 86 ° 30’ incidence angle and 1 ° 30’ divergence angle, the markings shall have average minimum intensities of 300 millicandelas for white and 170 millicandelas for yellow as measured with an approved retroreflectometer listed in the Subsection 632.02.05 of the QPL.

White: Daylight reflectance at 45 °/0° of 75% minimum. Yellow: Daylight reflectance at 45° /0° of 45% minimum. The daylight reflectance shall not change significantly when the preformed thermoplastic is properly applied to the roadway surface. The color pigments shall be selected and blended to provide a marking film which is w hite or yellow conforming to standard highway colors through the expected life of the film. The yellow color shall conform to Federal Test Standard No. 595B, Color No. 13538 or 13655.

value of 45 BPN when tested according to ASTM E303.

(150 psi) of cross section, at 3.15 mm (0.125 in.) thickness, when tested according to ASTM D638 except that a sample 150 mm x 25 mm (6 in. x 1 in.) shall be tested at a temperature between 21 °C and 27 °C (70 °F and 80 ° F) using a jaw speed of 250 mm to 300 mm (10 in. to 12 in.) per minute.

when a 25 mm x 150 mm (1 in. x 6 in.) sample is bent through an arc of 90° at a uniform rate in 10 seconds (9° per second) over a 25 mm (1 in.) mandrel, no cracking occurs in the test sample. The sample shall be conditioned prior to testing at 10 ± 1 ° C (50 ± 2 ° F) for a minimum of 4 hours. At least two specimens tested shall meet the flexibility requirements at 10 ° C (50 ° F) for a passing result.
