Bitumen 40-50 Supplier and Exporter
Iran bitumen penetration grade 40/50 is semi 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.Bitumen 40/50 is most used bitumen grade and basic material for all other bituminous products.
Softening point and penetration of bitumen 40-50
Penetration grade bitumen supplied by Iran Bitumen Co. is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by Iran Bitumen Co. is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 40/50 has penetration between 40~50 desi-millimeter and softening point between 52 ~ 60C. The penetration grade bitumen 40/50 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 60/70 has very strong viscosity compare to other grades.
