Bitumen SC800 is a slow-curing cutback bitumen designed for long-lasting surface treatment and prime coat applications. It blends penetration-grade bitumen with a high-boiling petroleum solvent, which allows for controlled evaporation and strong surface bonding.
At Basekim, we produce and export premium SC800 that meets global industry standards. Because of its balanced curing time and excellent penetration, SC800 performs especially well on roads and surfaces that require a durable and moisture-resistant base layer.
Why Choose Bitumen SC800?
Unlike faster-curing grades, bitumen SC800 cures gradually. This slower process allows it to penetrate deeper into the base layer before hardening. As a result, it creates a stronger adhesive bond between the sublayer and the asphalt surface. Road construction teams choose SC800 when working on coarse or absorbent base materials.
Additionally, SC800 offers excellent workability in warmer climates. While fast-curing grades might dry too soon, SC800 gives crews more time to complete the application correctly. This leads to reduced waste and improved long-term durability.
When the solvent evaporates, the residual bitumen stays behind, creating a waterproof, high-adhesion surface. That’s why SC800 is especially effective for prime coats and tack coats on gravel and crushed stone roads.
Technical Specifications – Bitumen SC800
Each batch of bitumen SC800 produced by Basekim is tested and verified under ASTM standards. Here’s a table that summarizes the most important technical properties:
| Property | Test Method | Specification |
|---|---|---|
| Kinematic Viscosity @ 60°C | ASTM D2170 | 800–1600 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% |
Applications of SC800 in Road Construction
Because of its slow curing rate, bitumen SC800 is ideal for prime coats on granular surfaces. Engineers also use it for sealing cracks, patching damaged roads, and enhancing the bond between pavement layers.
For rural roads, highways, and industrial zones, SC800 helps create a firm foundation. By soaking into the base material slowly, it strengthens the structure and reduces the chance of future failures.
