Bitumen SC250 is a slow-curing cutback bitumen created by blending penetration-grade bitumen with a slower-evaporating solvent. Thanks to this unique composition, SC250 works best for road projects that need deeper penetration and longer working times.
At Basekim, we manufacture and export premium SC250 with consistent quality and reliable performance. Our products meet international standards and help engineers and contractors build stronger, longer-lasting roads.
What Makes Bitumen SC250 Effective?
Bitumen SC250 slowly releases its solvent, allowing it to penetrate deep into unbound base layers. Because of this, it forms a strong bond between the base and the surface asphalt. The slow evaporation process ensures uniform coating and full absorption into granular or dusty surfaces.
This grade is especially useful when temperatures are high or when the project surface is very porous. In both cases, the longer setting time ensures better coverage. As a result, the road base gets stronger, more stable, and more resistant to water damage.
In surface dressing and patching, SC250 adds flexibility and reduces cracks. That’s why road repair crews prefer this product when they need quality results and minimal rework.
Technical Specifications – Bitumen SC250
Basekim performs strict quality control on every batch of bituminous SC250 to meet industry standards. The table below outlines the essential properties of this grade:
| 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 order includes a Certificate of Analysis and Safety Data Sheet. These documents help engineers and project managers ensure product compliance on site.
Applications of Bitumen SC250
Because SC250 cures slowly, it is widely used for prime coating, especially over gravel or crushed rock. It soaks into the base and binds loose particles together. After curing, it leaves behind a waterproof and adhesive layer.
SC250 also performs well in surface treatment, cold mix production, and sealing. Whether you’re building a new road or repairing an old one, SC250 strengthens the surface and extends pavement life.
Road agencies and contractors value SC250 for its workability, even in tough conditions. It stays fluid long enough for proper application while drying just fast enough to avoid project delays.
