Thermoplastic road marking has been
acknowledged as the single most
important contribution to road safety. It
provides incomparable night visibility when
measured against standard paint. Here is
why thermoplastic road marking is essential for today's roads.


- Excellent day/night visibility
- Superior durability / cost effectiveness
- Traffic ready in under 10 minutes
- High skid resistance
- Environmentally friendly


Infinite Road Marking uses Lafrentz and
Swarco Thermoplastic road marking
material, both are specially formulated to
withstand the extreme climatic conditions in
Canada. These are extrusion products, and
are both available in white and yellow.



Material Specifications:


The Material shall be manufactured for
application by extrusion onto pavement in hot, liquid form with glass spheres both mixed in and dropped onto the material after application.


Physical Requirements and Road Markings:

Color markings shall be brilliant white or yellow. Brightness is the value obtained with the Gardner Multipurpose Reflectometer when measuring 0 to 45 degrees daylight, luminous, directional reflectance with the green filter. The rating so obtained shall not be less than 70% for white or 45% for yellow.

Water Absorption:

Materials shall have no more than 0.5% by weight of retained water when tested by ASTM designation D-570, "Water Absorption of Plastics," procedure (A) (24 hours immersion).

Softening Point:
    
Materials shall have a softening point of not less than 90 degrees Celsius, as determined by ASTM designation E-28, "Method of Test for softening Point by Ring and Ball Apparatus."

Specific Gravity:

Specific gravity of the thermoplastic compound at 25 degrees Celsius shall be from 1.9 to 2.2.

Impact Resistance:

Shall not be less than 1.13 newton-meters at 25 degrees Celsius after the material has been heated for hours at 204 degrees Celsius, and cast into bars of 25mm cross-sectional area, 75mm long and placed with 25mm extending above the vice in a cantilever beam tester using the 2.82 newton-meter scale. This instrument is described in ASTM designation D-246.

Abrasion Resistance:

Materials shall have a maximum weight loss of 1.0 grams when subjected to 200 revolutions on a Taber Abrader at 25 degrees Celsius using H-22 Calibrate wheels weighted to 500 grams. The test samples shall be prepared by forming representative lots of materials at a thickness of 3mm + 0.1mm on a 100mm square plate. The test surface shall be kept wet during test.

Indentation Resistance:

The reading of the Shore Durometer, type A2, as described in ASTM designation D-1706 after fifteen seconds and using a 0.907kg weight, shall not be less than the amounts specified below when the material is tested after heating for temperatures:

Resistance:

5cm x 5cm test sections shall show no signs of degradation after exposure to:

5% NaCl (24 hour immersion)
5% CaCl (24 hour immersion)

(Mixed in and dropped onto the material after application)
