Product Description Product
AASHTO American standard hot melt paint is a type of hot - melt coating that complies with the standards set by the American Association of State Highway and Transportation Officials (AASHTO). It is typically a solid at room temperature and can be melted by heating for application. Once applied to the surface and cooled, it forms a durable layer, commonly used in road marking applications to ensure clear and long - lasting markings for traffic guidance.
AASHTO standard hot melt paint offers several advantages, which include:
1. Durability:
- High resistance to wear and tear: It can withstand the continuous abrasion from vehicle tires, heavy traffic, and various weather conditions, maintaining the integrity and clarity of the markings for a long time. This is crucial for ensuring the safety of road users as clear markings are essential for guiding traffic.
- Resistance to fading: The pigments used in AASHTO standard hot melt paint are of high quality and have excellent lightfastness, which means the color of the markings remains vivid and does not fade easily over time, even when exposed to sunlight, rain, and other environmental factors.
2. Visibility:
- Good reflectivity: The paint contains glass beads or other reflective materials that enhance its reflectivity at night or in low-light conditions. This allows drivers to clearly see the road markings, improving driving safety and reducing the risk of accidents.
- Quick drying and clear markings: After application, the hot melt paint dries quickly, ensuring that the markings are sharp, clean, and well-defined. This helps drivers to accurately identify the road markings and follow the correct driving directions.
3. Adhesion:
- Strong adhesion to the road surface: The AASHTO standard requires that the hot melt paint has good adhesion to various types of road surfaces, such as asphalt and concrete. This ensures that the markings stay firmly attached to the road, even in the face of heavy traffic, rain, snow, and other adverse conditions, reducing the risk of the markings peeling off or becoming damaged.
- Compatibility with different road materials: It can be used on different types of road surfaces, making it a versatile choice for road marking applications.
4. Cost-effectiveness:
- Long service life: Due to its high durability and resistance to wear and tear, the hot melt paint requires less frequent maintenance and replacement, resulting in lower long-term costs. Although the initial cost of hot melt paint may be higher than some other types of road marking materials, its long lifespan makes it a cost-effective option in the long run.
- Efficient application: The application process of hot melt paint is relatively efficient, and a large area can be marked in a short time. This reduces labor costs and minimizes the impact on traffic during the construction process.
5. Environmental adaptability:
- Resistance to temperature changes: It can perform well in a wide range of temperatures, from high temperatures in summer to low temperatures in winter. It does not soften at high temperatures or become brittle at low temperatures, ensuring the stability and durability of the markings.
- Waterproof and moisture-resistant: The hot melt paint forms a waterproof and moisture-resistant coating after application, which can prevent water from infiltrating into the markings and affecting their performance. This is particularly important in areas with high rainfall or humid climates.
Applications Range of Hot Melt Line Paint
Application of thermoplastic road marking paint
1. Industrial Areas:
Thermoplastic road markings are used in industrial zones for safety and traffic management purposes.
Parking spaces, directional arrows, and pedestrian crossings in parking lots are often marked using thermoplastic paint.
Thermoplastic markings are used for lane demarcation, edge lines, and center lines on roads and highways.
Airports use thermoplastic markings for runway and taxiway guidance due to the material’s durability and reflective properties.
