BNA Bitumen Emulsion made up of three basic ingredients which include Bitumen, an emulsifying agent and water. It is a well-known fact that asphalt and water will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. Emulsions which have positively charged ions may be used at ambient temperatures with aggregates, which do not have to be completely dry. Emulsions are less hazardous to use and can be applied in the wider range of conditions and used for many applications including road surfacing.

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.

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.
