Bitumen-Penetration

Penetration Grades

Bitumen for Road Construction and Waterproofing Applications

Bitumen penetration grades typically range from 10 to 400, with lower numbers indicating harder consistency and higher numbers indicating softer consistency. The most common penetration grades include10/20, 30/40, 40/50, 60/70, 80/100, 85/100 and 120/150.

What is Penetration Grade Bitumen?

Penetration grade bitumen is one of the most common types of bitumen used in road construction. It is a petroleum-grade bitumen that is manufactured at different viscosities through fractional or vacuum distillation of crude oil.

Its distinctive temperature-viscosity relationship is essential in determining various performance parameters, such as the following:

–

–

Rheology
–

Adhesion
–

Durability
–

Application temperatures

What is 60/70 Bitumen used for?

–

Penetration grade bitumen is commonly used in road surfacing and industrial projects. It is one of the standard bitumen that is used as a paving grade bitumen and is essential in the production of high-quality asphalt pavements. This type of bitumen is also important because it bounds the aggregates and helps the bituminous mix become more stable and cohesive
–

Among all the subgrades of penetration grade bitumen, the 60/70 is one of the most commonly used in road construction projects. It is usually mixed with aggregates to form hot mix asphalt and pave roads. Since it provides additional strength when mixed with the aggregates, the 60/70 bitumen is ideal for paving high-traffic roads. Additionally, this bitumen has excellent workability and cures quickly, meaning that roads can be paved faster and open to motorists sooner.

What is 85/100 Bitumen?

–

Another commonly used bitumen subgrade is the 85/100. It is a type of penetration grade bitumen with high heat-retention properties. Because the 85/100 bitumen holds heat longer, it allows the asphalt to be easily molded on the road. Its heat-retention properties also allow the asphalt not to crack even in low temperatures. This makes the 85/100 bitumen the perfect choice for constructing sturdy and long-lasting roads in high-altitude and cold climate areas.

Packing and Delivery

New Steel Drum

This method of bitumen packaging is the most regular used method. The Drums are made of cold-rolled steel in order to protect them against corrosion and are coated with rust-proof black painting.

Drum types:

There are two types of steel drums; Normal steel drums with the capacity of 180 kg net bitumen and short drums which is loaded by 150 kg.

Container loading:

Drums are mostly suitable for container loading. Every 20’ container can get 110 pcs of normal drums.

Jumbo Bags

Jumbo bags request in Bitumen industry is increasing due to their environmental and operation advantages. Each jumbo bag contains 1 metric ton of bitumen loadable to 20’ containers in 20 bags.

Bitu Bags

Bitu bags of 300 kg are another alternatives to jumbo bags for easier transportation and their potential in maximizing the container space usage.

Bulk in Vessel

In this method, the bitumen is transported by heated tankers to the port to be loaded into the special bulk vessels of bitumen. Mostly in 5000 metric ton vessels are used but also other capacities can be alternated.

Packing :	150 or 180 kg new steel drums, 300 kg Bitu Bags, 1 ton Jumbo bag, Bulk in vessel
Delivery terms:	FOB Jebel Ali Dubai, CFR and CIF every port on the world.
Samples:	Can be sent . Shipping cost to be coverd by the customer.
