Bitumen and Its Different Grades
What is Bitumen?
Bitumen is a viscous, black, and sticky petroleum-based material primarily used in road construction, waterproofing, and industrial applications. It is produced through the distillation of crude oil and is known for its waterproofing, adhesive, and durability properties.
Different Grades of Bitumen
Bitumen is classified based on its penetration value, viscosity, or performance under specific conditions. The most common types include:
- Penetration Grade Bitumen (Most Common for Roads)
Classified by penetration value (hardness level) measured in 0.1 mm units.
The lower the penetration number, the harder and more durable the bitumen.
Common grades & uses:
– Bitumen 40/50 → Heavy-duty roads, airport runways
– Bitumen 60/70 → Highways, expressways (best for tropical climates)
– Bitumen 80/100 → Provincial & city roads, waterproofing - Viscosity Grade Bitumen (VG)
Classified by viscosity at 60°C (better for temperature variations).
Used in hotter climates and industrial applications.
Common grades:
– VG-10 → Low-traffic roads, spraying applications
– VG-30 → Highways & urban roads (widely used in India & hot climates)
– VG-40 → Heavy-duty pavements & industrial use - Performance Grade (PG) Bitumen
Designed to withstand specific temperature ranges.
Used in regions with extreme temperature fluctuations.
Example: PG 64-22 (can handle +64°C max and -22°C min temperatures). - Oxidized (Blown) Bitumen
Produced by blowing air into hot bitumen, making it harder & more resistant to aging.
Used for roofing, waterproofing, and industrial coatings.
Grades: Ranging from Bitumen 85/25 to 115/15. - Cutback Bitumen
Bitumen mixed with solvents (kerosene, diesel) for cold weather applications.
Used for road repair & spray sealing. - Emulsified Bitumen
Bitumen mixed with water & emulsifiers for cold applications.
Used in pothole repairs, surface treatments, and rural roads.
Choosing the Right Bitumen Grade
- Highways & heavy traffic roads → 60/70 or VG-30
- Urban roads & general paving → 80/100 or VG-10
- Roofing & waterproofing → Oxidized bitumen
- Cold weather construction → Cutback or Emulsified bitumen

Which grade of bitumen is most important in Togo
In Togo, 60/70 penetration grade bitumen is the most common type of bitumen used for road construction. This semi-hard bitumen is well suited to the country’s hot climate and is widely used in the production of hot mix asphalt for subgrades and wearing courses. Its balance of flexibility and durability makes it ideal for roads that experience medium to heavy traffic loads.
For infrastructure that is under greater stress, such as airport runways and heavily trafficked urban roads, polymer modified bitumen (PMB) is increasingly being used. PMB increases elasticity and resistance to deformation, offering a sustainable solution to rutting problems on roads. In Togo, PMB products such as PG76-22 are widely used.
Additionally, VG-30 viscosity grade bitumen is used in areas with higher temperatures and heavy traffic. VG-30 offers excellent resistance to deformation and cracking, making it suitable for heavy pavements.
In summary, while 60/70 penetration grade remains the primary choice for public road construction in Togo, PMB and VG-30 are preferred for projects requiring improved performance due to stress conditions or higher temperatures.

Key Ports for Bitumen Grades Togo Discharge
- Port of Lomé – Oil Jetty & Mineral Quay
Oil Jetty: Designed for efficient unloading of petroleum products, including bitumen. The jetty operates 24/7 and has no reported berthing delays, ensuring timely discharge operations.
Mineral Quay: Equipped to handle bulk commodities such as bitumen. However, this quay has experienced berthing delays ranging from 20 to 30 days due to congestion.
Storage Facilities: The port offers extensive storage options, including 115,000 m² of sheltered space and large tanks managed by the Togolese Storage Company for hydrocarbons. - Adétikopé Dry Port (PIA)
Function: Acts as an inland extension of the Port of Lomé, facilitating the handling and transit of goods, including bitumen, to landlocked neighboring countries such as Burkina Faso, Niger, and Mali.
Capacity: Spanning over 20 hectares, the facility can accommodate up to 12,500 containers and is connected to major transport corridors, enhancing the distribution efficiency of bitumen inland.
