Highly Reflective AASHTO M249 Hot Applied Road Marking Paint for
High-Traffic Areas
Product Description
Hot applied road marking paint is a type of traffic paint used for
road markings, such as lane lines, pedestrian crossings, and other
highway symbols. It's made from a combination of resins, pigments,
and glass beads, and it is applied to the pavement in a molten
state, where it hardens quickly upon cooling to form a durable,
long-lasting marking.
Here are some key characteristics of thermoplastic pavement
markings:
1. Durability: Thermoplastic markings are highly resistant to wear from traffic,
weather, and other environmental factors, making them suitable for
high-traffic areas.
2. Retroreflectivity: The glass beads embedded in the material help enhance the
visibility of the markings, especially at night or in low-light
conditions, by reflecting headlights from vehicles.
3. Application: The material is applied hot, at temperatures typically between
375°F and 400°F (190°C to 204°C). It can be applied using
specialized equipment that melts the material and spreads it on the
road surface.
4. Fast Setting: Once applied, thermoplastic markings cool and harden quickly,
allowing roads to be reopened to traffic soon after the markings
are made.
5. Types: There are different types of thermoplastic materials based on the
specific needs of the application, including standard, thick-film,
and preformed thermoplastic markings.
Thermoplastic pavement markings are commonly used for highway,
roadway, and airport applications due to their durability,
visibility, and resistance to fading.
Usage:
- Clean the surface to be coated thoroughly.
- Ensure the surface is dry and free from contaminants.
- Apply the thermoplastic coating using appropriate application
methods such as spraying or brushing.
- Heat the coating to the required temperature to ensure proper
adhesion and curing.
Detailed Process of Hot Applied Road Marking Paint Construction
1. Road Cleaning
Before operation, the nearby area must be cleaned to ensure that
there are no impurities such as oil, water, fallen leaves, weeds,
ect., so as not to affect the adhesion effect, flatness and
reflection effect of the line.
2. Set the Point and Mark Line
In the process of sampling, the calculation and measurement must be
carried out in strict accordance with the construction drawings.
Measure the several lanes that need to be drawn on the road, set
the point, and then mark it with a stone pen. Use titanium dioxide
powder to glue the rope for the elastic line. After the rope is
removed, it will be corrected and improved to ensure that the line
shape is clear and accurate.
3. Apply the Primer
The lower coating is a common binder in hot melt marking
construction. It is applied to the highway road surface, which can
make the hot melt coating better adhere to the road surface.
4. Spray the Paint
Before construction, first check the relevant coating equipment.
Then heat the paint.
When the trolley moves forward, the paint will form a coating film
on the road, and a layer of glass beads should be sprinkled on the
coating film during the coating process.
When the trolley moves forward, take the reference line as the
ruler, control the thickness and width of the line, and ensure the
coordination, clarity and smoothness of the line connection between
the straight line and the curve.
Note: During the coating process, in order to avoid the
sedimentation and separation of the paint, it is necessary to stir
the paint frequently.
5. Check and Correct
After the coating is completed, check and correct the line shape,
check the spread of glass beads, etc.
After confirming that it is correct, the construction site will be
cleaned up.
After the line is dried and hardened, the relevant construction
equipment can be transferred, the safety facilities can be
dismantled, and the traffic can be opened.

Advantages of Hot Melt Marking Paint
The advantages of hot melt marking paint are as follows:
Strong adhesion and durability
- It has strong adhesion to the road surface, ensuring that the
marking lines remain intact, clear, and not easily peeled off under
the long-term influence of vehicle rolling and various
environmental factors.
- It has excellent wear resistance and a long service life,
reducing the waste of manpower and material resources caused by
repeated constructions and the obstruction to normal traffic.
Good visibility
- Reflective glass beads can be mixed during construction, so the
marking lines have good reflective performance at night, which can
greatly improve the safety and efficiency of driving at night and
make it easier for drivers to see the road markings clearly under
low-light conditions.
- The color of the paint itself is bright and eye-catching,
providing clear guidance for drivers and pedestrians even during
the day.
Rapid drying and convenient construction
- It dries quickly and can be opened to traffic shortly after
construction, effectively reducing the impact on traffic and
improving construction efficiency.
- The construction method is relatively simple. Usually, a special
marking device is used to scrape or spray the melted paint on the
road surface, which is easy to operate and can form neat and
uniform marking lines.
Economy
- Although its initial purchase cost may be relatively high, due to
its long service life, it has good cost-effectiveness in the long
run and can reduce the maintenance and re-marking costs of road
markings.
Environmental adaptability and maintainability
- It has good weather resistance and water resistance, can adapt to
various harsh natural environments, maintain vividness for a long
time, and is not easy to fade or be damaged due to natural aging,
rain washing, and other factors.
- The later maintenance is relatively easy. If the marking lines
need to be modified or removed, the paint can be softened by
heating and then processed.
