Bitumen 60/70

About Bitumen 60-70

Penetration Grade Bitumen ( like Bitumen 60-70) is classified using penetration property. It is a kind of bitumen, which is provided during the process of oxidation of vacuum bottom (the bitumen Definition: production feed-stock that derives from distillation tower residue in vacuum oil refineries) at bitumen production units in a manner that its penetration point (kind of test to indicate the hardness of bitumen) becomes between 60/70.

Derivatives formed of hydrocarbons in a complex colloidal system compose to bitumen structure. In addition, its low-grade of crude oil composed of complex, heavy hydrocarbons. In an oil reservoir, bitumen is a thick, viscous fluid. Bitumen extract from the ground.
Bitumen extracting is hard but it can bubble naturally to surface in petroleum seeps. Seeps are places where fossil fuels and petroleum products leak out of the Earth instead of being trapped deep below the ground. In these seeps, bitumen, asphalt, and tar bubble up into pools.
In addition, bitumen is the main fossil fuel component of oil sands. Bitumen combination with asphalt is solid, uses in paving.

Penetration Grade

This system developed in 1900s to characterize the register of semi-solid asphalts. Penetration grading quantifies the following asphalt concrete specs:

Penetration depth of a 100g needle 25°C.
Flash point temperature
Ductility at 25°C.
Solubility in trichloroethylene
Thin film oven test(effects of short-term aging that occurs during mixing with hot aggregate)
Retained penetration
Ductility at 25°C.
Less viscous asphalt = deeper needle will penetrate.
Also penetration depth is empirically correlated with asphalt binder performance. Furthermore, high penetration asphalt binders “soft” used for cold climates and low penetration asphalt binders “hard” used for warm climates.

Bitumen 60/70 Applications

Bitumen 60/70 mainly uses in construction. Furthermore, it serves in paving and roofing apples.

85% of bitumen uses in asphalt industry.

10% used in roofing, because it`s waterproofing qualities help make roofs function well.

5% using for sealing and insulating purposes in building materials such as carpet tile.

In addition, it uses in soundproofing, explosives, fence post coating, mildew protection, a binder in briquettes, a backing to mirrors, shoe solesand soil stabilization

The exact chemical composition of bitumen 60/70 is dependent on the chemical complexity of original crude oil also manufacturing process. Penetration bitumen grade 60/70 has properties of 60~70 desi-milimeter and softening point 46~58oC.

Bitumen 60-70 Softening Point and Penetration

Penetration grade bitumen supplied by PUB-LTD is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. In addition, it`s produced from remain of crude oil after cracking and removing hydrocarbon. Also Penetration grade bitumen 60-70 has penetration between 60~70 desi-millimeter also softening point between 48 ~ 52oC. The penetration grade 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 bitumen 60/70 has very strong viscosity compare to other grades.


PUB-LTD guaranty the quality of Bitumen 60-70 with arrangement of international inspector. Actually For checking the quality and quantity of the bitumen during the loading to vessel and also controlling the production by QC by batch test report before shipping. PUB-LTD guaranty the quality to meet with ASTM/EN 12591.

Drumming facilities majorly located in the Middle East and manufacture high quality new steel drums produced by companies all in conformity to EN DIN standards or ASTM Standards.
