General Information of Cutback Bitumen MC-30
Cutback MC-30 is a medium-curing cut-back asphalt, made from penetration grade asphalt cement and a medium volatility diluent. This significantly reduces viscosity, thus ensuring easier handling and application, especially in cold weather. Moreover, it ensures smoother coverage on road surfaces.
Composition
It consists of bitumen dissolved in solvents like kerosene. Consequently, these solvents effectively lower the viscosity, making it easier to use. Therefore, this mixture is known as cutback bitumen, suitable for diverse applications such as road maintenance and surface treatment.
Standards
Our MC-30 meets ASTM D2028-97 standards. Furthermore, it’s commonly used for pavement construction and maintenance, blending bitumen with solvents like kerosene, white spirit, and naphtha for optimal performance and reliability.
Uses of Cutback Bitumen MC-30
Priming and Coating
Used as a primer on road surfaces, it binds base materials to asphalt layers. Moreover, kerosene adjusts its viscosity based on project needs, enhancing adhesion. Additionally, this improves the durability of the paved surfaces significantly.
Waterproofing
It waterproofs surfaces, plugs voids, and bonds loose particles effectively. As a result, it improves surface durability and prevents water damage. Furthermore, this process extends the lifespan of the pavement considerably.
Mixing Applications
Ideal for patching and stockpile mixtures, it often contains adhesion agents for better aggregate coating. Thus, it ensures long-lasting repairs. In addition, it enhances the strength of the repaired areas remarkably.
Packing of Cutback Bitumen MC-30
Packaged in bulk tankers and thick steel drums on pallets to prevent leaks during transport and storage. Consequently, this packaging ensures product integrity. Moreover, the robust packaging facilitates easier handling and distribution.
Safety of Cutback Bitumen MC-30
Precautions
Refer to Safety Data Sheets. Store at low temperatures, away from ignition sources. Additionally, use PPE and avoid skin contact for enhanced safety. Moreover, always ensure proper ventilation during application.
Environmental Safety
Prevent product and washings from entering stormwater or sewer systems. This practice significantly reduces environmental risks. Furthermore, adopting eco-friendly disposal methods helps in maintaining environmental sustainability.
