Road bitumen 60/70 and 80/100
Road bitumen penetration grade 60/70 and 80/100 is semi solid bitumen grade for Road construction using as paving grade in roads and suitable for road paving and repair also for the production of asphalt pavements with below technical specification. This grade of road bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Road bitumen 60/70 or 80/100 is most used as raw material to make other grades of bitumen and called basic material for all other bituminous products.
What is Road bitumen 60/70 & 80/100?
Road bitumen 60/70 has the highest-boiling point, heaviest and most polar fraction from the vacuum distillation of crude oil. Road bitumen 80/100 is composed of Asphaltens and molten. The heavy insoluble asphaltene molecules give Road bitumen 60/70 its body and softening point while the maltenes are oily and make asphalt flexible. Asphaltene molecules are soluble in aromatic solvents like toluene but insoluble in heptane. The maltenes are heptane-soluble molecules and less aromatic.
Softening point and penetration of Road bitumen 60/70
Penetration grade Road bitumen supplied by is pure petroleum grade road bitumen, manufactured from vacuum bottom by passing hot air. The Road bitumen supplied by is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade Road bitumen 60/70 has penetration between 60~70 desi-millimeter and softening point between 48 ~ 52C. The penetration grade Road bitumen 60/70 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of Road bitumen 60/70 has very strong viscosity compare to other grades.
Quality of road bitumen
Guaranty the quality of road bitumen with arrangement of international inspector to check quality and quantity of the road bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. guaranty the quality to meet with ASTM/EN 12591.
Packing of Road bitumen
It is 180 (+/-2.5) Kg New Steel Drum, Original Package, 0.6 mm thickness of Drum // Each 20” FCL: 110 Drums

Road bitumen packing
Road bitumen bag should be easily dissolved at 160C and start to melt from 110C.this type of Road bitumen bag is normally using for penetration grade of Road bitumen like Road bitumen 60/70 and Road bitumen 80/100.
In summer time outside temperature in port of loading is very hot and should be taken more care on compress of bag since it is liquid at more than 60C.So it should be protected by bracket or case.
Road bitumen bag 50kg
Road bitumen in 50Kg bag is different that 25kg and protected by different layer and composited with yarn and craft. This type of bag is possible to fill it and stuff in container without pallet.
Road bitumen in 300Kg polycube bag
Polycube is just useful for export and in case you load in truck will leak and damage. Even at destination should be delivered to final destination and then discharge to prevent damage. It is designed as per of dimension of container and container protecting the bags and outside of container if you carry will damage!
Road bitumen in 800Kg and 1000Kg 1MT jumbo bag
Road bitumen in jumbo bag is most safe and east handling from loading to destination. Jumbo bag should be designed for Road bitumen and if you buy from market and fill Road bitumen will become fat or collapse. Normally design of road bitumen in jumbo bag is in the bottom the size is bigger than top and should have angle to become stable.
Density of Road bitumen
Density is between 1.01 to 1.06 (Kg/dm3)
It means that 1.010kg to 1.060kg is one desi cubic meter.
Each tons of asphalt needed 70Kg Road bitumen and the rest is aggregates.
Supply capacity of Road bitumen
Able to supply 30000MT monthly packed in drum, bag and bulk.
The volume quantity is exporting by since we are in contact with seven refineries of in North, East, West and South so Turkey ,UAE and other neighbor country can purchase with less transport cost.
Road bitumen refineries
Most famous road bitumen refineries is Tupras and Socar. Apart from these which selling road bitumen, there are some other private factories that making road bitumen with VB (Vacuum bottom) of refineries. The Road bitumen quality is Ok if they use pure VB and price compatible since their cost is much less.
Company selling road bitumen 60/70 packed in steel drum and bag also supplying the material in bulk vessel which public refineries unable to arrange such service in the same time.
