Explanations about Cutback Bitumen MC800

Cutback bitumen MC-800 is a type of bitumen that has been liquefied by blending it with a solvent, typically a high-flash point petroleum distillate. The “MC” designation indicates that it is a medium-curing cutback bitumen. Here are some key explanations about MC-800:

• Viscosity: MC-800 has a relatively high viscosity compared to other cutback bitumen grades, typically around 800 centistokes at 60°C. This viscosity influences its flow characteristics and application methods.
• Medium Curing Rate: Similar to other MC grades, MC-800 has a medium curing rate. This means that it penetrates and bonds with the underlying surface at a moderate rate, providing adequate time for application and achieving proper adhesion.
• Application Temperature: Due to its higher viscosity, MC-800 may require higher application temperatures compared to lower viscosity cutback bitumen grades. It is typically applied at elevated temperatures to ensure proper flow and coverage.
• Uses and Applications: MC-800 is commonly used in road construction and maintenance for various applications, including prime coating, tack coating, dust control, patch repair, seal coating, and grouting. Its higher viscosity makes it suitable for specific requirements where increased adhesion or durability is needed.
• Environmental Considerations: Like other cutback bitumen grades, MC-800 contains volatile solvents, which can pose environmental and health risks if not handled properly. Proper storage, handling, and disposal procedures are necessary to minimize these risks and ensure environmental safety.

Understanding the properties and characteristics of MC-800 is essential for selecting the appropriate application methods and ensuring the desired performance in road construction and maintenance projects. Additionally, adherence to safety regulations and guidelines for handling and application is crucial to ensure the safe and effective use of MC-800.

In many places, Cutback Bitumen MC-800 use is restricted to patching materials for use in cold weather cutback MC-800 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. Cutback MC-800 use in the road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface course. Its purpose is to bind the granular material of the base course to the asphalt layer. Usual application is by spray using a distributor.

Cutback bitumen MC-800 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.

Our MC-800 Cutback Bitumen complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97 reapproved in 2004. Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by ZUMRUT Company are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by ZUMRUT Company is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. The cutback bitumen (Asphalts) supplied by ZUMRUT are blended from petroleum grade bitumen as stated herein

Cutback Bitumen MC-800 Applications

Cutback bitumen MC-800 is typically used in road construction and maintenance for various applications that require a higher viscosity and stronger adhesion. Here are some common applications:

1. Prime Coating: MC-800 can be applied as a prime coat to prepare the base surface before laying asphalt. Its higher viscosity ensures better penetration and bonding with the underlying surface, enhancing the effectiveness of subsequent asphalt layers.
2. Tack Coat: It serves as a tack coat to promote adhesion between asphalt layers during pavement construction or rehabilitation. The higher viscosity of MC-800 provides stronger bonding between the layers, improving the overall durability and performance of the pavement.
3. Patch Repair: MC-800 is used for patching and repairing damaged areas on asphalt pavements, such as potholes and cracks. Its higher viscosity ensures better adhesion and durability of the repair, extending the lifespan of the pavement.
4. Seal Coating: MC-800 can be employed in seal coating applications to protect asphalt surfaces from moisture, oxidation, and wear. Its higher viscosity allows for better coverage and adhesion, resulting in a more durable and long-lasting protective coating.
5. Grouting: In some cases, MC-800 is used as a grout for filling voids and cracks in concrete structures. Its higher viscosity ensures better penetration and sealing, providing improved waterproofing and structural integrity.

Uses of Cutback Bitumen MC-800

Cutback bitumen MC-800, with its higher viscosity, finds specific uses in road construction and maintenance where increased adhesion and durability are required. Here are some common uses:

• Heavy-Duty Prime Coating: MC-800 is utilized as a prime coat in road construction projects where a stronger bond between the base surface and subsequent asphalt layers is necessary. Its higher viscosity ensures better penetration and adhesion, particularly on rough or porous surfaces.
• Tack Coat for High-Stress Areas: In areas subjected to heavy traffic loads or frequent turning movements, MC-800 serves as a tack coat to enhance the bond between asphalt layers. Its superior adhesion properties help prevent delamination and increase the structural integrity of the pavement.
• Patch Repair in High-Traffic Zones: When repairing potholes, cracks, or other surface defects in high-traffic areas, MC-800 is preferred due to its stronger bonding capability and durability. It ensures long-lasting repairs that withstand heavy traffic loads and harsh environmental conditions.
• Seal Coating on Highways and High-Volume Roads: MC-800 is used in seal coating applications on highways and high-volume roads to provide a durable protective layer against moisture, oxidation, and wear. Its higher viscosity allows for better coverage and adhesion, resulting in superior performance and longevity.
• Grouting for Critical Infrastructure: In critical infrastructure projects such as bridges, tunnels, and airport runways, MC-800 serves as a grouting material for filling voids, gaps, and cracks. Its high viscosity ensures thorough penetration and sealing, providing enhanced waterproofing and structural stability.
