MC30 Cutback Bitumen
MC30 Cutback Bitumen is a medium-curing cutback bitumen designed to improve workability and ease of application on roads and asphalt surfaces. By blending bitumen with suitable solvents, MC30 achieves lower viscosity, allowing it to spread and penetrate aggregates efficiently without the need for high temperatures. This makes it especially suitable for areas where heating equipment is limited or for applications in cooler conditions.
After the solvent evaporates, MC30 Cutback Bitumen restores its natural properties, providing excellent adhesion and durability. It is commonly used for surface treatments, connecting asphalt layers, and protective road coatings. With balanced viscosity and good ductility, MC30 ensures a uniform distribution of bitumen while maintaining resistance to cracking and environmental effects, making it an ideal choice for medium-duty paving projects.
