Bitumen MC250 is a medium-curing cutback bitumen widely used in road construction, particularly in warm and moderate climates. Because it combines penetration-grade bitumen with a controlled percentage of petroleum solvent, it offers a balanced mix of fluidity and binding strength. This makes it ideal for surface dressing, prime coats, patchwork, and large-area applications that require uniform coverage. Many contractors rely on Bitumen MC250 from Basekim because we provide consistent quality, strong technical support, and reliable global logistics.
Bitumen MC250 flows easily at normal temperatures, allowing workers to apply it without the need for excessive heating. After application, the solvent begins to evaporate gradually. As the curing process continues, the remaining bitumen forms a sticky, water-resistant film that bonds strongly with aggregates or the base surface.
This steady curing rate provides several advantages:
Longer working time, ensuring smooth and uniform application
Reduced runoff, which minimizes material waste
Consistent penetration, preventing over-absorption in weaker bases
Improved adhesion, supporting long-term asphalt stability
Because of these characteristics, MC250 is especially useful for large road areas, rural highways, and repair works in warm regions where rapid-curing grades may evaporate too quickly.
In warm climates, rapid-curing grades can dry before workers finish spreading them. However, MC250 cures at a moderate pace, allowing better control during application. As a result:
Coverage improves
Asphalt layers adhere more effectively
Waste decreases
Work crews maintain productivity
This makes Bitumen MC250 highly efficient for climates such as the Middle East, Africa, South Asia, and hot coastal regions.
Every batch of Bitumen MC250 supplied by Basekim is tested in our certified laboratory to ensure full compliance with ASTM standards. Below are the key technical specifications:
| Property | Test Method | Specification |
|---|---|---|
| Kinematic Viscosity @ 60°C | ASTM D2170 | 250–500 cSt |
| Flash Point (Tag Open Cup) | ASTM D3143 | Min 38°C |
| Distillation Residue | ASTM D402 | Min 55% by volume |
| Penetration of Residue | ASTM D5 | 100–250 dmm |
| Ductility of Residue | ASTM D113 | Min 100 cm |
| Solubility in TCE | ASTM D2042 | Min 99% |
Each shipment includes a Certificate of Analysis (COA) and Safety Data Sheet (SDS) to support compliance with regional and international project requirements.
Because of its balanced curing rate and strong bonding capability, Bitumen MC250 is widely used in:
1. Prime Coats
It penetrates granular bases effectively, creating a strong platform for asphalt layers.
2. Surface Dressing
Its adhesive qualities help bind aggregates during sealing and maintenance operations.
3. Road Repair and Patching
MC250 works well for repairing cracks, potholes, and localized failures.
4. Joint Sealing
It improves flexibility and prevents water intrusion into pavement joints.
5. Bonding Layers in Multi-Layer Pavements
Its flowability ensures uniform coverage and enhances cohesion between old and new asphalt layers.
Because MC250 improves durability and water resistance, it plays a critical role in extending pavement lifespan.

Bitumen MC250 is a medium curing cutback bitumen used in road construction for prime coats, surface treatments, and cold mix asphalt production. Its balanced curing rate allows effective penetration into base layers while providing strong adhesion for asphalt applications.
Bitumen MC250 has a higher viscosity and slower curing rate than MC70, making it suitable for projects that need longer working time. This property ensures better coating of aggregates and improved bonding in heavy-duty road bases.
Bitumen MC250 has a kinematic viscosity range of 250–500 cSt at 60°C, a flash point above 38°C, and a minimum residue by distillation of 55%. These specifications provide stability, durability, and reliable performance in road construction (See full specifications).
