Manufacturer of Rapid Curing Cutback Bitumen RC-70 in UAE and Turkey

Cutback Bitumen RC-70 Description

Cutback Bitumen RC-70 is an asphalt cement that has a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha added to make the asphalt liquid at ambient temperatures and improve its ability to coat aggregates. Two letters followed by a numerical digit designate or name a cutback asphalt.
Cutback asphalt can contain between 12 and 40 percent distillate. The high demand for the distillates to be used in energy applications and ever-increasing air quality regulations have caused a steady decline in the use of cutback asphalt.
When gasoline or naphtha is used to flux asphalt cement, the final product is called “rapid curing” (RC) cutback asphalt. Specifications permit up to 45 percent distillate in manufacturing an RC-70 cutback asphalt.

Our Cutback Bitumen RC-70 complies with cutback petroleum asphalts of the rapid-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 bitumen’s are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumen’s 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 Co are blended from petroleum grade bitumen as stated herein.

Cutback Bitumen RC-70 Applications

Cutback Bitumen RC-70 is commonly used in road construction and maintenance for various purposes such as:

• Prime Coating: It can be used as a prime coat to prepare the surface before applying asphalt layers, promoting adhesion between the surface and the subsequent asphalt layers.
• Tack Coat: RC-70 can also serve as a tack coat to ensure proper bonding between pavement layers, preventing slippage and increasing the structural integrity of the road.
• Surface Dressing: It is used in surface dressing applications to waterproof and protect the road surface from water infiltration and weathering, extending the lifespan of the pavement.
• Patching and Repair: RC-70 can be used for patching and repair work on roads, providing a durable and reliable solution for filling potholes and cracks.
• Dust Control: It can be applied to unpaved roads to control dust emissions, improving road safety and reducing environmental impacts.

Why should we choose bitumen RC-70?

Choosing Bitumen RC-70 offers several advantages:

• Versatility: Bitumen RC-70 can be used in various road construction and maintenance applications, including prime coating, tack coat, surface dressing, patching, and dust control, providing flexibility and versatility in project implementation.
• Rapid Curing: The solvent in Bitumen RC-70 evaporates quickly, leading to rapid curing and faster construction times, reducing project durations and minimizing traffic disruptions.
• Cost-Effectiveness: The faster curing time and reduced construction durations associated with Bitumen RC-70 can result in cost savings by lowering labor and equipment expenses and minimizing project delays.
• Enhanced Performance: Bitumen RC-70 promotes better adhesion between pavement layers, leading to improved structural integrity, durability, and longevity of road surfaces, reducing the need for frequent repairs and maintenance.
• Environmental Benefits: Bitumen RC-70 can help mitigate dust emissions on unpaved roads, improving air quality and reducing environmental impacts, while its rapid curing properties contribute to lower greenhouse gas emissions during construction.

The main advantage of Cutback Bitumen RC-70

The main advantage of Cutback Bitumen RC-70 is its rapid curing capability combined with enhanced fluidity at lower temperatures. This makes it ideal for applications in colder climates or where heating equipment may not be available, as it can be applied directly without pre-heating. The rapid evaporation of solvents ensures that RC-70 sets quickly, enabling fast bonding with aggregates and reducing downtime in road construction projects. Additionally, its high penetration capability allows it to bond effectively with base layers, enhancing durability and adhesion for long-lasting road surfaces.

The difference between Cutback Bitumen RC-70 and RC-30

1. Viscosity
   RC-70 has a higher viscosity (70–140 cSt at 60°C) compared to RC-30 (30–60 cSt at 60°C).
   This means RC-70 is thicker and more resistant to flow than RC-30, making it better suited for applications requiring a more stable binder.
2. Bitumen Content
   RC-70 typically contains around 65% bitumen, while RC-30 contains around 55% bitumen.
   The higher bitumen content in RC-70 makes it a stronger binder, providing greater durability and adhesion in applications where a more robust material is needed.
3. Evaporation Rate
   RC-30 has a faster evaporation rate than RC-70 due to its lower viscosity and higher proportion of volatile solvents.
   This makes RC-30 more suitable for surface treatments where quick setting is needed, while RC-70 is better for applications that require a slightly longer curing time for increased penetration and stability.
4. Applications
   RC-30: Primarily used for prime coating and surface dressing, especially in cases where rapid setting and a thin application layer are preferred.
   RC-70: Ideal for cold weather applications, patching, and repairs. Its higher viscosity makes it suitable for heavier surface treatments and projects requiring a thicker layer of binder.
5. Strength and Durability
   Due to its higher bitumen content and viscosity, RC-70 provides greater strength and durability than RC-30, making it better suited for applications with higher traffic loads or those requiring enhanced stability.

Packing of Bitumen RC70

Packing of cutback bitumen RC-250 is in new thick steel drum on the pallet to prevent any leak inside of the container, IBC Tank, and also bulk in bitutainer.

Guaranty and Safety of Bitumen RC-70

The guarantee and safety of Bitumen RC-70 depend on several factors:

1. Quality Assurance: Purchasing Bitumen RC-70 from reputable suppliers who adhere to industry standards and regulations ensures product quality and consistency.
2. Compliance: Ensuring that the Bitumen RC-70 meets relevant specifications and standards set by regulatory authorities guarantees its suitability for intended applications.
3. Proper Handling: Following recommended handling procedures and safety precautions during storage, transportation, and application minimizes the risk of accidents and ensures worker safety.
4. Environmental Considerations: Adhering to environmental regulations and best practices for the disposal of Bitumen RC-70 and its by-products reduces environmental impact and promotes sustainability.
5. Performance Testing: Conducting performance tests, such as viscosity, penetration, and softening point tests, verifies the quality and suitability of Bitumen RC-70 for specific applications, providing assurance of its performance.
