Bitumen 60/70 seller in drum and jumbo bag SGS approved

Bitumen 60/70

Bitumen 60/70 means penetration of bitumen is between 60 to 70 and compare bitumen 80/100 which means penetration is between 80 to 100 is harder since needle penetrating less.This grade of bitumen is made by blowing of hot air to vacuum bottom and as much as heating the raw material bitumen will get hard and penetration will decrease.It is mostly using in road constrution, paving and waterproofing also coating.

How you buy high quality bitumen 60/70?

Quality of bitumen has many items to check but after passing the penetration and you make sure it is in order with very simple test you can recognize the quality is good or bad:

  • Less smell means low sulphor(somebody adding sulphur to bitumen to get weight)
  • Viscosity in range(Somebody useing vaccum resin instead of vaccum bottom and harm quality)
  • Spot test must be negative( Simple factories heating by direct fire and buring the bitumen)

From which factory you have to buy bitumen 60/70

There are four types of bitumen factories and price also different caus of investment and outcome capacity  

1. If factory produce bitumen continusly the price is higher and quality is the best and TFOT and againg test of bitumen also will pass (Our factory is producing base on continuse technology) 

bitumen factory continuous production

2. Batching production unit and using hot oil cyrculating technology in the blowning tower to prevent buring bitumen and just one point heating.

3. Batching producting with direct heating but there is chace to burn the bitumen

Blening production which is last option for the buyer since it has alwayse problem on viscosity

What is bitumen 60/70?

Bitumen 60/70 has the highest-boiling point, heaviest and most polar fraction from the vacuum distillation of crude oil. Bitumen 60 70 is composed of asphaltene and maltene. The heavy insoluble asphaltene molecules give 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 bitumen 60/70

Penetration grade bitumen supplied by ATDM is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by ATDM is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 60/70 has penetration between 60~70 desi-millimeter and softening point between 48 ~ 52C. The material 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.

Guaranty/warranty of bitumen 60/70

ATDM guaranty the quality of bitumen 60/70 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. ATDM guaranty the quality to meet with ASTM/EN 12591.
