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.

What is BNA Cold Mix ? (BCM)

BNA Cold Mix (BCM) Comes in polymer modified cold bitumen or standard bitumen from, guaranteed to permanently repair potholes, utility cuts, overlays, and edge repairs in bitumen / asphalt or concrete. BNA cold mix (BCM) is currently being used by many state and privet organizations, construction companies and contractors across the country in the bulk from. BNA international has now introduced an all new high quality Bagged Cold Mix (BCM) that works in ALL weather conditions, it even works in water....

BNA Concrete Expansion Joint sealant (BNA CEJS) is composed of a mixture of materials, including Oxidized Bitumen that will form a resilient and adhesive compound capable of affectively sealing joints in concrete against the infiltration of moisture and foreign material throughout repeated cycles of expansion and contraction with temperature changes.

BNA Cutback Grade Bitumen is normally used in spraying and in some mixing application. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline and naphtha controlling the curing time. Cutbacks are divided into 2 types, Rapid Curing (RC) and Medium Curing (MC) depending on the solve used. Commonly used for road and pavement construction and maintenance. Cutback MC 30 is blended with a solvent such as Kerosene, a medium curing petroleum cutter.
