Cutback Bitumen RC-3000 | High-Performance Road Construction Material by Pars Bitumen
Introduction
Cutback Bitumen RC-3000 is one of the most widely used grades of rapid-curing cutback bitumen, designed specifically for road construction and maintenance applications. Manufactured and supplied by Pars Bitumen, a leading producer of premium bitumen products in Iran, RC-3000 combines superior workability with high adhesion, ensuring excellent performance even under demanding conditions.
What Is Cutback Bitumen RC-3000?
Cutback Bitumen RC-3000 is a liquid form of bitumen that has been blended with a petroleum solvent to reduce its viscosity. This modification makes it easier to apply at lower temperatures compared to pure bitumen.
The “RC” in RC-3000 stands for Rapid Curing, indicating that the solvent used in this grade evaporates quickly after application, allowing the bitumen to harden rapidly and bind effectively to aggregates.
Chemical Composition and Properties
The RC-3000 grade is formulated with high-quality bitumen base and fast-evaporating solvents such as naphtha or gasoline. Its key specifications include:
Property Specification Description
Viscosity @ 60°C (cSt) 3000 (approx.) Ensures optimal flow and coating characteristics
Flash Point (°C) Min 38 Safe for transportation and handling
Distillation Test (to 360°C) 10–75% recovered Indicates solvent volatility and curing rate
Penetration of Residue (dmm) 100–200 Balanced hardness and flexibility
Solubility in Trichloroethylene ≥ 99% High purity and homogeneity
(These values may vary slightly based on manufacturing standards and local climate requirements.)

Applications of Cutback Bitumen RC-3000
RC-3000 is primarily used in road construction, surface dressing, and repair works. Thanks to its high penetration and fluidity, it is ideal for:
Prime coating on granular bases before applying asphalt layers
Tack coating to promote adhesion between existing and new pavement layers
Surface dressing for sealing and protecting road surfaces
Cold mix asphalt production, especially in cooler regions where heating facilities are limited
Maintenance of potholes and cracks, ensuring strong bonding and waterproof sealing
At Pars Bitumen, each batch of RC-3000 undergoes strict quality control to guarantee uniformity, durability, and excellent performance in all climatic conditions.

Storage and Handling Recommendations
Store RC-3000 in a cool, dry, and well-ventilated area away from heat sources.
Avoid direct sunlight and open flames — the product is flammable due to its solvent content.
Use personal protective equipment (PPE) during handling and application.
Ensure containers are tightly sealed when not in use to prevent solvent loss.
Environmental and Safety Considerations
While Cutback Bitumen RC-3000 provides excellent performance, users should consider its environmental impact due to solvent emissions. Pars Bitumen continuously invests in research to develop eco-friendly alternatives, including bitumen emulsions that offer similar performance with reduced VOC emissions
