Paving Grade BitumenBitumen 80 / 100
Bitumen penetration grade 80/100 supplied by ZigguratOil is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by ZigguratOil is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 80/100 has penetration between 80~100 desi-millimeter and softening point between 45 ~ 52C. The penetration grade bitumen 80/100 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen has very strong viscosity compare to other grades.
Intended use
Paving Grade Bitumen 80/100 can be used to a limited extent for asphalt concrete and SMA in wearing courses, on the assumption that the mix resistance to rutting is confirmed. It can also be used for the production of asphalt emulsions.
