BNA Bitumen 85/25

BNA Oxidized (Blown) Grade Bitumen is product by vigorous air blowing. BNA Oxidized (Blown) Bitumen 85/25 is product by either a staggered or a continuous blowing process. The heated penetration Grade Bitumen under controlled environment is blown with air which controls the oil content in the Bitumen which it is oxidized. The different grades produced for suited applications are distinguished by two numbers to indicate the mid points of their softening point and penetration ranges. They are more ‘rubber like’ and less temperature susceptible than the paving grades. Fuel oil can be added to the process to increase the penetration if required for custom applications and requirements.

RECOMMENDED APPLICATION RATE

Recommended Spraying Temperature: Blown grade bitumen shall be broken up into small pieces and heated slowly to the application temperature of ° – 230°C.
