MC250 Bitumen
MC250 is a slow-setting cutback bitumen widely used in road construction and civil engineering.1 Composed of 55% bitumen and 45% solvent, it’s an ideal choice for various applications due to its unique properties.
Benefits of MC250:
- Ease of Application: Its liquid form makes it easy to apply and spread, requiring minimal specialized equipment.
- Strong Adhesion: MC250 adheres exceptionally well to various surfaces like aggregates, asphalt, and metals.
- Durability: It’s resistant to weather elements and wear, ensuring the longevity of construction projects.
- Rapid Drying: The solvent content allows MC250 to dry quickly, enabling traffic to resume soon after application.
- Crack Resistance: Its flexibility prevents asphalt from cracking due to temperature fluctuations and stress.
- Cost-Effective: Its affordable price and ease of application make it a cost-effective option.
Applications of MC250:
- Base Course: Used as a binder between base and surface courses in road construction, preventing material slippage.
- Prime Coat: Applied to prepare surfaces before paving and as a sealant for various surfaces, including roofs and tanks.
- Bituminous Macadam: Used in bituminous macadam mixes for roadways, sidewalks, and parking areas.
- Sealing: Used to fill gaps and cracks between blocks and asphalt, preventing water penetration.
- Waterproofing: Applied as a moisture barrier under tiles, mosaics, and bricks to prevent water ingress.

Key Considerations:
- Storage: Store in sealed containers away from direct sunlight and heat sources.
- Safety: Wear protective gear, including gloves, masks, and goggles.2
- Compatibility: Choose the appropriate solvent based on the surface and weather conditions.
- Selection: Select MC250 based on the application and climate. Petroleum solvents are suitable for hot, dry climates, while emulsified solvents are better for humid conditions.
Conclusion: MC250 is a versatile bitumen with numerous applications in the construction industry.3 Its ease of use, durability, and cost-effectiveness make it a popular choice. For optimal results, consider the specific application and environmental factors when selecting and using MC250.
