AASHTO M249 Standard Reflective Thermoplastic Paint for Durable Road Marking
Product Description
AASHTO M249 thermoplastic paint is a high-performance road marking material designed to create durable and reflective pavement markings. It complies with the specifications set by the American Association of State Highway and Transportation Officials (AASHTO) under the M249 standard, ensuring high quality and reliable performance for traffic safety applications.
Applications
- Highway lane markings.
- Pedestrian crosswalks.
- Parking lot lines.
- Stop lines and other road traffic symbols.
Detailed Process of Thermoplastic 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.

Key Characteristics Hot Melt Road Marking Paint
-
Thermoplastic Composition:
This paint is made from thermoplastic resins, enabling it to be applied in a molten state and solidify quickly as it cools, forming a durable layer on road surfaces.
-
High Durability:
It is engineered to withstand heavy traffic loads, adverse weather conditions, and UV exposure, maintaining its visibility and integrity for extended periods.
-
Reflectivity:
The material includes reflective glass beads that provide retro-reflective properties, ensuring visibility both during the day and at night, even in wet conditions.
-
Fast Drying:
The paint cools and hardens quickly after application, reducing road closure times and minimizing traffic disruption.
-
Skid Resistance:
Anti-skid properties are achieved through the inclusion of fillers and texture additives, ensuring safer road conditions for vehicles.
-
Environmentally Compliant:
Modern formulations reduce volatile organic compound (VOC) emissions and avoid hazardous substances like lead, adhering to environmental and health regulations.
