Manufacture of Bitumen grade 40/50

General definition of Bitumen 40/50

Bitumen penetration grade 40/50 is a semi-hard penetration grade bitumen used in road construction and repair. Its unique temperature-viscosity relationship is crucial for determining performance parameters like adhesion, rheology, durability, and application temperatures. This standard Penetration Grade of Bitumen ASTM D946M is suitable for road construction and producing superior asphalt pavements, particularly in road and airport constructions.

Blown Asphalt 40/50 has a penetration between 40-50 desi-millimeters and a softening point between 52-60C. It has a thermoplastic property similar to synthetic resin material, which softens with heating and hardens when cooled. This grade has a strong viscosity compared to other grades. It is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. The production process is automated, resulting in a constant and homogeneous finished product quality. Penetration Grade Bitumen can be used in various applications. supplied in any grade and are designated by two numbers to indicate the mid-points of their penetration ranges.

How is 40/50 Bitumen Produced?

40/50 bitumen is produced by refining crude oil through fractional distillation, heating and separating it into different fractions based on boiling points. The heaviest fraction is obtained, which is then processed to meet specific specifications.

To produce penetration bitumen 40/50, it undergoes tests to determine its penetration value, which indicates its hardness. The penetration value ranges between 40 and 50 Deci millimeters, and Asphalt Cement has a penetration value between 40 and 50 Deci millimeters, hence its name.

Application of Bitumen grade 40/50

This grade of bitumen is also mainly used in the manufacture of hot mix asphalt. also, Bitumen is suitable for road construction and repair for asphalt pavements with superior properties. Bitumen is used for hot mixed asphalt because of the properties of very strong viscosity compared to other grades. Also used in specialized applications like airport runways and also in very heavy traffic volume roads in coastal cities in the country.

Bitumen 40/50 Advantages

Bitumen Penetration 40/50 is a thermoplastic material, which means that when it is subjected to high temperatures, it will become more flexible, and when it is exposed to cold temperatures, it will become more rigid. The kind of crude oil that is refined into bitumen as well as the refining process itself are both potential factors that might have an effect on the manner in which bitumen behaves in terms of temperature and stiffness. Maintaining equilibrium in the surrounding environment. A lifespan that is much longer than the typical one for the product. Extraordinarily strong adhesion to the great majority of different kinds of materials in their diverse forms.

Handling and Storage

Handling: Skin contact with the product should be avoided. Inhalation of fumes should be avoided as far as is
reasonably practicable.

If the formation of vapors is a risk, then additional ventilation should be provided. Handle away from
sources of ignition and heat. Do not smoke, eat or drink during use.

Storage: No special requirements. Asphalt is normally used upon receipt.
Refer to the relevant Technical Data Sheet for the specific product.

Guaranty of bitumen 40/50

Quality of bitumen penetration grade with the arrangement of the international inspector to check the quality and quantity of the bitumen penetration grade during the loading to the vessel and control the production by QC by batch test report before shipping.

Packing

Bitumen grade is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and Jumbo Bags or Bitubag and 10 & 20kg Tubular cartons.
