🛣️ Use of Thermoplastic in Road Marking – Explained!
In modern road construction and maintenance, thermoplastic road marking has become a preferred choice due to its durability, visibility, and long-term cost efficiency. Let’s understand what thermoplastic is and why it’s widely used on highways and roads.
✅ What is Thermoplastic?
Thermoplastic road marking paint is a type of material that is heated to around 200°C and applied hot to the road surface. As it cools down, it hardens and forms a durable and reflective coating. It often contains glass beads and titanium dioxide for visibility and brightness.
🚧 Why is Thermoplastic Used in Road Markings?
Here are the top reasons:
1️⃣ High Durability
Thermoplastic markings can withstand heavy traffic, rain, heat, and dust. Unlike normal paint, they do not fade or wear off easily, making them ideal for high-traffic roads and highways.
2️⃣ Reflectivity at Night
It includes retro-reflective glass beads that reflect headlights, making the road markings visible even at night or in low light conditions.
3️⃣ Quick Setting Time
Once applied, thermoplastic hardens in a few minutes, reducing the time needed to block roads for maintenance.
4️⃣ Anti-Skid Properties
Additives can be mixed to make the surface non-slippery, improving safety for vehicles and pedestrians.
5️⃣ Weather Resistance
Whether it’s intense heat or monsoon, thermoplastic stays intact for longer, reducing the need for frequent re-application.
6️⃣ Eco-Friendly & Low Maintenance
It is free of harmful solvents and requires minimal maintenance once applied properly.
📍 Where is Thermoplastic Used?
-
Center lines and lane dividers
-
Zebra crossings and stop lines
-
Arrows and directional signs
-
Speed breakers and school zones
-
Symbols for cycling lanes and parking areas
🔧 How is it Applied?
-
Road surface is cleaned and primed.
-
Thermoplastic is heated to 180–200°C in a special machine.
-
It is poured or sprayed in required shapes.
-
Glass beads are sprinkled or pre-mixed for reflectivity.
-
It hardens quickly upon cooling.
