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 Grading:

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 100 g 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 Softening point and penetration:

Penetration grade bitumen supplied by PUBLTD 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. Penetration grade bitumen 60-70 has penetration between 60~70 desi-millimeter also softening point between 48 ~ 52C. 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.

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 46~58 Deg.C.

Upgrading Bitumen:

Bitumen upgrading is the chemical treatment of bitumen that uses to increase its value by creating a high quality crude oil substitute known as a synthetic crude oil. Generally this involves reducing the viscosity of bitumen to allow for shipment. So bitumen processed into fuels at existing refineries.


Through a series of different chemical processes it is possible to make low-quality, thick bitumen into a higher quality synthetic crude oil. The first step is the removal of naturally occurring light components while also recovering the diluent used to transport the bitumen. This procedure occurs in diluent recovery unit. These operate similarly to a fractional distillation tower in the way they separate these components out.

Removed light gas oils sent to hydrotreaters and the diluent is recycled. The next step involves the vacuum distillation of the leftover bitumen component in a vacuum distillation unit. This unit removes the rest of the gas oils and sends them to the hydrotreaters. Heavy components remains from vacuum distillation unit, sending to conversion units. Then, bitumen travels to a conversion unit.

Residue is The processes are performed on large molecules. Fluid cokers break up long chain bitumen molecules into more valuable short chain molecules through a thermal conversion. These short chain molecules can include heavy gas oil, light gas oil, and naphtha. Breaking complex hydrocarbon chains is known as coking. Hydrocracker uses a catalyst and hydrogen to convert bitumen into more useful gas oils and naphtha.

This hydrotreating removes sulfur and nitrogen, replacing it with hydrogen. Naphtha and gas oil products are pumped to hydrotreater units. These use catalytic reactors to remove the impurities, resulting in a crude oil blend of naphtha, light gas oil, and heavy gas oil
