Introduction to Bitumen MC70

Cutback Bitumen MC70 is a highly effective and versatile material widely used in construction and industrial applications. Its detailed specifications, beneficial properties, and diverse applications make it a preferred choice for many professionals.

What is Bitumen MC70?

 Medium-Curing Cutback Bitumen 70, is a type of bitumen that is diluted with a solvent to reduce its viscosity, making it easier to work with at lower temperatures. The “70” in MC70 refers to the viscosity of the bitumen. This product is primarily used for priming and tack coating in road construction.

Key Specifications of Bitumen MC70

Understanding the specifications of  Cutback Bitumen MC70 is crucial for its effective application. Here are the primary specifications:

1. Viscosity: Bitumen MC70 has a viscosity of 70 centistokes at 60°C, ensuring it flows well and can be easily applied.
2. Flash Point: The flash point of MC70 is generally around 38°C, indicating the temperature at which it can vaporize to form an ignitable mixture in air.
3. Distillation: During the distillation process, a specific percentage of the solvent is expected to evaporate at designated temperatures. This ensures the bitumen achieves the desired consistency for application.
4. Penetration: The penetration value indicates the hardness of the bitumen. For MC70, the penetration ranges typically between 120-150 dmm at 25°C.
5. Solubility: Bitumen MC70 should be highly soluble in trichloroethylene, with a minimum solubility of 99%.

Composition of Cutback Bitumen MC70

It is composed of bitumen and a medium-curing solvent, usually kerosene or a similar petroleum distillate. The composition allows for easy application and adequate curing time, which is essential for roadworks and industrial applications. The solvent evaporates after application, leaving behind a viscous bitumen residue that binds materials together.

Properties of Bitumen MC70

Understanding the properties of  MC70 helps in selecting it for appropriate applications. Here are the key properties:

1. Adhesiveness: Bitumen MC70 has excellent adhesive properties, ensuring it binds well with aggregates and other materials.
2. Flexibility: It remains flexible under various temperature conditions, preventing cracks in road surfaces.
3. Durability: The residual bitumen left after the solvent evaporates provides long-lasting durability to the surfaces treated with MC70.
4. Water Resistance: Bitumen MC70 offers good water resistance, making it suitable for use in areas prone to water exposure.

Application of Bitumen MC70

It is versatile and used in several applications:

1. Priming: It is used as a primer on granular surfaces to prepare them for subsequent layers of asphalt.
2. Tack Coating: Bitumen MC70 serves as a tack coat between old and new asphalt layers to ensure proper bonding.
3. Road Construction: Its excellent adhesive properties make it ideal for various road construction projects, including surface dressing and pavement construction.
4. Industrial Uses: It is used in waterproofing and protective coatings in industrial settings.

Advantages of Using Bitumen MC70

• Ease of Application: The reduced viscosity allows for easy application even at lower temperatures.
• Cost-Effective: The use of a solvent makes it more economical for large-scale projects.
• Versatility: Suitable for a range of applications, from road construction to industrial uses.
• Enhanced Performance: Provides excellent adhesion, durability, and water resistance, enhancing the lifespan of treated surface
