General definition of bitumen 35/50
Bitumen Grade 35/50 is a type of penetration grade bitumen that is produced by the non-destructive refining of crude oil during petroleum refining. exporting bitumen is penetration hard grade and softening between 35 to 50. bitumen is hard penetration grade bitumen used as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with the below technical specification. Bitumen is heavy traffic grade which ensures long-term savings as it allows for a thinner pavement design, which uses up to 30% less asphalt than traditional designs while ensuring extended pavement life. Its penetration grade is between 35 to 50 and its softening point is between 58 to 66°C. Bitumen is a premium brand that is dark brown or black in color similar to cement-shape semi-solid or viscous liquid form produced by the non-destructive refining of crude oil during petroleum refining.

Application of Bitumen 35/50
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.
Guaranty of Bitumen grade 35/50
The 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 of Bitumen 35/50
Bitumen Penetration Grade 35/50 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and Jumbo Bags or Bitubag and 10 & 20kg Tubular cartons.
