WHAT IS THERMOPLASTIC?
Thermoplastic is a pavement marking that has been used in the
U.S. since 1958 with continuing good results.
A mixture of glass beads, binder, pigment and filler materials,
thermoplastic, as its name suggests, becomes liquid when heated.
What does each ingredient in the mixture do?
The pigment supplies the color, white or yellow, to the thermoplastic.
Glass beads, in conjunction with the pigment, give the material the
retro- reflectivity necessary for its bright night appearance.
The binder is a mixture of plasticizer and
resins that holds all of the other ingredients together.
Filler materials include calcium carbonate,
sand and/or other inert substances that provide bulk.
What thermoplastic is made of and how it is applied are
the keys to its durability and long lasting retro-reflectivity.
When properly formulated and correctly applied, thermoplastic
should last from five to eight years under normal traffic conditions.
Correct Application of Thermoplastic
Temperature is the most important factor in the proper mixing, melting
and bonding of thermoplastic.
Heated to a temperature of 420° F and agitated properly,
the dry thermoplastic compound becomes a homogenized liquid.
Applied at this temperature, the thermoplastic melts into
the upper surface of the asphalt, forming a thermal bond.
When installed on porous surfaces, such as open-graded asphalt or
tined concrete, the hot liquid thermoplastic fills all voids, creating a
good mechanical lock on concrete and a thermal bond on asphalt.
Thickness of the applied thermoplastic should be as specified. A minimum
thickness of 90 mils is important to the material's
ability to hold the heat necessary for good bonding.
The thermal bonding that occurs when application is at the proper thickness
ensures the thermoplastic's durability and long term retro-reflectivity.
Being raised above the road surface, combined with the retro-reflectivity
produced by the glass beads, makes thermoplastic more
visible from a distance and at night. The thickness also contributes to improved
retro-reflective performance in wet conditions and the exceptional durability
of the product.
The amount of glass beads, both mixed in with the compound
and dropped on the installed line, must be correct.
Drop-on beads must be applied evenly and adhered to a depth of 60%.
Proper application thickness, temperature and
formulation, in conjunction with correct bead coatings,
ensure that the bead depth is accurate.
Thermoplastic Coverage Rate
Surface temperature must be above 50 degrees F.
Application temperature is approximately 400 degrees F.
Temperature should never exceed 450 degrees F.
Coverage estimate at a mil thickness of .125 is as follows:
1 ton = 1500 sq. ft. coverage
4" wide line = 4500 linear feet per ton
6" wide line = 3000 linear feet per ton
8" wide line = 2250 linear feet per ton
12" wide line = 1500 linear feet per ton
