Bitumen penetration grade 85/100 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. This penetration grade bitumen is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. Bitumen 85/100 is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 85/100 has penetration between 85~100 desi-millimeter and softening point between 41~ 49C. The penetration grade bitumen 85/100 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 85/100 has very strong viscosity compare to other grades.
