Using bitumen 10/20 in modern asphalt

Bitumen 10/20 ensures long-term savings because it allows for a thinner pavement design, which uses up to 30% less asphalt than traditional designs, while ensuring extended pavement life.iranrequest exporting bitumen 10/20 its penetration hard grade and softening between 10 to 20.iranrequest bitumen 10/20 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

Softening point and penetration of bitumen 10/20

Penetration grade bitumen supplied by iranrequest is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by iranrequest is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 10/20 has penetration between 10~20 desi-millimeter and softening point between 58 ~ 66 c. The penetration grade bitumen 10/20 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 10/20 has very strong viscosity compare to other grades.

Guaranty|warranty of bitumen 10/20

iranrequest guaranty the quality of bitumen 10/20 with arrangement of international inspector to check quality and quantity of the bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. iranrequest guaranty the quality to meet with ASTM/EN 12591.
