Bitumen SC 800 is a premium slow-curing cutback bitumen specifically engineered for road construction and maintenance projects that demand superior penetration, adhesion, and durability. Designed to perform efficiently in a wide range of climates, SC 800 is widely used in prime coats, surface treatments, and cold mix asphalt applications. Its controlled curing rate and optimal viscosity make it a preferred choice for contractors seeking reliability, workability, and long-term pavement performance.
As infrastructure development continues to grow globally, the demand for high-quality cutback bitumen grades like SC-800 has significantly increased. Whether for highways, rural roads, airport runways, or municipal streets, Bitumen SC 800 provides consistent results that meet international standards.
Bitumen SC 800 belongs to the family of slow-curing (SC) cutback bitumen. It is produced by blending penetration grade bitumen with a controlled amount of petroleum solvent (typically gas oil or diesel range cutter stock). This blending process reduces the viscosity of the base bitumen, making it easier to apply at lower temperatures without the need for excessive heating.

ToggleThe “800” in SC 800 refers to its kinematic viscosity range, which provides a balanced flow rate and penetration capability. Compared to other cutback grades such as SC 250 or SC 70, SC 800 offers thicker consistency and slower evaporation, making it suitable for specific applications where deeper penetration and stronger bonding are required.
Slow curing rate
Excellent adhesion to aggregates
High penetration capability
Suitable viscosity for prime coat applications
Reliable performance in moderate to warm climates
Easy application without excessive heating
Bitumen SC 800 is widely used in road construction and pavement maintenance. Its properties make it highly versatile and dependable in both new construction and rehabilitation projects.
One of the most common uses of Bitumen SC 800 is as a prime coat on prepared granular base layers before asphalt paving. The slow-curing nature allows the bitumen to penetrate deeply into the base material, creating a strong bond between the base and the asphalt overlay.
This ensures:
Reduced dusting
Improved waterproofing
Stronger structural bonding
Enhanced pavement lifespan
SC 800 is frequently used in cold mix asphalt, especially in areas where hot mix plants are unavailable. Its workable viscosity enables easy mixing with aggregates at ambient temperatures, making it ideal for rural and remote road projects.
For surface treatments and patching work, Bitumen SC 800 provides excellent aggregate coating and long-lasting adhesion. It is especially useful in preventive maintenance strategies aimed at extending pavement service life.
In road repair operations, SC 800 is used to ensure proper bonding between old and new asphalt layers. Its penetration capability enhances cohesion, reducing the risk of delamination.
Thanks to its slow-curing formulation, SC 800 penetrates deeper into granular surfaces compared to faster-curing grades. This improves bonding and enhances structural integrity.
Since it can be applied at lower temperatures, Bitumen SC 800 reduces energy consumption and heating costs. Contractors benefit from operational efficiency and lower overall project expenses.
The strong adhesive properties of SC 800 result in improved resistance to moisture damage, stripping, and cracking.
The viscosity range of SC 800 allows smooth spraying and uniform coverage, ensuring consistent application quality.
Bitumen SC 800 performs particularly well in moderate to warm climates, where controlled curing is necessary for optimal pavement bonding.
While exact specifications may vary depending on manufacturing standards and regional regulations, typical properties include:
Kinematic viscosity at 60°C: Approximately 800 cSt
Flash point: High enough to ensure safe handling
Distillation residue: High-quality base bitumen
Penetration of residue: Within specified range
Solubility in trichloroethylene: ≥ 99%
These properties ensure compliance with international road construction standards and guarantee consistent performance.
To maintain the quality of Bitumen SC 800:
Store in clean, dry tanks away from moisture contamination
Maintain recommended storage temperatures
Avoid overheating to prevent solvent loss
Use appropriate safety measures during handling
Because SC 800 contains petroleum solvents, proper ventilation and safety precautions are essential during storage and application.
Many contractors ask: What is the difference between SC 800 and SC 250?
The primary difference lies in viscosity and curing time.
SC 250 has lower viscosity and faster curing
SC 800 has higher viscosity and slower curing
SC 800 is preferred when deeper penetration and stronger bonding are required, especially for prime coat applications. Its slower evaporation allows more time for absorption into the base layer.
Not all cutback bitumen products offer the same performance. The quality of the base bitumen and the blending process directly impact durability and application efficiency.
