MC 250

Cutback Medium Curing 250 (MC250) is a highly versatile liquid bitumen, widely used in road construction and maintenance projects. It is a medium-curing cutback bitumen formulated by blending standard penetration-grade bitumen with a petroleum solvent. This process ensures optimal fluidity, making MC250 a preferred choice for various applications, especially in regions requiring cost-effective and efficient road solutions.

What is Cutback Medium Curing 250?

The term Cutback Medium Curing 250 refers to a type of bitumen designed to provide enhanced fluidity and workability. The “250” indicates the kinematic viscosity, which ensures its suitability for applications like prime coating, surface dressing, and tack coats.

Key Features of Cutback MC250

1. Medium-Curing Solvent:

   • The petroleum solvent evaporates at a moderate rate, allowing sufficient time for application and penetration.

2. High Fluidity:

   • MC250 is easy to handle and apply, even at ambient temperatures, reducing the need for extensive heating equipment.

3. Superior Bonding:

   • It creates a strong bond between the base layer and asphalt, ensuring durability and stability in road construction.

Common Applications of MC250

1. Prime Coat:

   • Prepares granular bases for asphalt overlays by enhancing adhesion and stabilizing the surface.

2. Tack Coat:

   • Acts as an adhesive layer between existing asphalt surfaces and new overlays.

3. Surface Dressing:

   • Protects roads from water infiltration and improves resistance to wear and tear.

Advantages of Using Cutback MC250

• Energy Efficient:

  • Minimal heating is required, saving costs and reducing carbon footprint.

• Enhanced Penetration:

  • The medium-curing properties allow deep penetration into the substrate, ensuring strong bonding.

• Versatile Usage:

  • Suitable for a wide range of road construction and maintenance activities.

Environmental Considerations

While MC250 offers many benefits, it contains petroleum solvents that release volatile organic compounds (VOCs). Proper storage, handling, and application are essential to minimize environmental impact.
