85/25

Oxidized Bitumen 85/25, also known as Oxidized Asphalt, is a high-quality product produced by blowing hot air into penetration-grade bitumen. This process transforms the bitumen into a more rubbery and harder material than its original form. As a result, it has reduced thermal sensitivity, a higher softening point, and a penetration index (PI) greater than standard road construction bitumen (2 < PI < 8).

Supply of Oxidized Bitumen 85/25 by ROYAL GLOBAL ENERGY

At ROYAL GLOBAL ENERGY, we are committed to supplying premium-quality Oxidized Bitumen 85/25 sourced from reputable producers. We ensure that our products meet the highest industry standards, offering a consistent penetration index and optimal softening point.

The softening point of Oxidized Bitumen 85/25 is determined using the ASTM D36 Ring and Ball method, while the penetration value is measured according to IP49 or ASTM D5.

Handling and Storage Recommendations

For optimal performance and safety during the use of Oxidized Bitumen 85/25:

• Maximum Safe Heating Temperature: Do not exceed 230°C.
• Pre-Breaking: Break the bitumen into smaller pieces before heating to ensure even melting and avoid localized overheating.
• Temperature Control: Use accurate thermometers close to the heat source due to bitumen’s poor thermal conductivity
