FAQ: What is Oxidized Bitumen 110/30?

❓ What is Oxidized Bitumen 110/30?

🧪 Blown Asphalt 110/30 is a hard bitumen grade with a softening point of 110°C and a penetration value of 30. Manufacturers create it by blowing air through hot penetration bitumen, which changes its molecular structure. As a result, it becomes more thermally stable and rigid, making it ideal for demanding industrial use.

❓ Where is Blown Asphalt 110/30 commonly used?

🏗️ This grade is widely used in roofing materials, cable sheathing, pipe coatings, and waterproofing membranes. Because it holds its form under heat and load, it performs well in hot climates and static applications. Engineers choose it when reliability and structural stability are key.

❓ How does 110/30 compare to softer bitumen grades?

🔍 Compared to grades like 90/40 or 85/25, 110/30 is much harder and more heat-resistant. While softer grades allow for movement and flexibility, 110/30 remains firm and stable. This makes it ideal for high-load, high-temperature applications where dimensional integrity matters.

❓ Can Oxidized Bitumen 110/30 handle extreme heat conditions?

🌡️ Yes, it performs exceptionally well in high-temperature environments. It resists softening, deformation, and sagging, even during continuous thermal exposure. That’s why it’s trusted in industries requiring long-lasting protection under heat stress.

❓ How is the quality of Oxidized Bitumen 110/30 tested?

📊 Laboratories test it using industry standards like ASTM D5 for penetration, ASTM D36 for softening point, and ASTM D113 for ductility. These tests verify its durability and suitability for industrial applications, ensuring consistency across batches.
