Viscosity Grades

Bitumen for producing high-quality asphalt mixes

Viscosity grade bitumen, which is categorized based on its viscosity at a specific temperature, offers improved performance and durability in various climates and traffic conditions. It provides better resistance to rutting, cracking, and deformation, making it ideal for use in highways, urban roads, airports, and other infrastructure projects where durable pavement is essential.

What is Viscosity Grade Bitumen?

Viscosity grade bitumen is a type of bitumen that is categorized based on its viscosity at a specific temperature. Viscosity is a measure of a fluid's resistance to flow, and in the case of bitumen, it is crucial for determining its performance in various applications, particularly in road construction.

Viscosity grade bitumen is commonly classified using two systems: the penetration grading system and the viscosity grading system. While the penetration grading system measures the hardness or softness of bitumen based on its penetration depth under specified conditions, the viscosity grading system assesses bitumen's flow characteristics at a specific temperature.

Which common grades Viscosity Bitumen has?

Common viscosity grades of bitumen include VG-10, VG-20, VG-30, VG-40, and VG-50, where the number indicates the average kinematic viscosity in centistokes at 60°C. Higher viscosity grades such as VG-40 and VG-50 are typically used in regions with high temperatures, heavy traffic loads, or where higher resistance to rutting and deformation is required. Lower viscosity grades like VG-10 and VG-20 are suitable for colder climates or applications where improved workability and compaction are necessary.

What are the advantages of Viscosity grade Bitumen?

Viscosity grade bitumen offers several advantages in road construction, including better resistance to rutting, cracking, and deformation, enhanced durability, improved adhesion to aggregates, and reduced susceptibility to temperature-related damage. These properties make viscosity grade bitumen an essential material for producing high-quality asphalt mixes that can withstand the rigors of traffic and environmental conditions.

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.
