Bitumen MC3000 – Heavy-Duty Cutback Bitumen from Basekim
Bitumen MC3000, also known as MC-3000 medium curing cutback bitumen, is a high viscosity binder designed for heavy duty road construction that demands deep base penetration, slow curing, and a strong, durable bituminous film. It is widely used as a prime coat on granular and stabilized road bases, ensuring a long lasting bond between the base and asphalt layers. Because of its controlled curing behavior and strong adhesive properties, bitumen MC3000 delivers exceptional performance in highways, runways, industrial pavements, and regions with hot climates. At Basekim, we manufacture and supply premium MC3000 cutback bitumen that meets strict ASTM standards, guaranteeing consistent quality for large scale infrastructure projects worldwide.
What Makes Bitumen MC3000 Unique?
Bitumen MC3000 is specifically engineered for applications where both strength and controlled curing are essential. Unlike lighter cutback grades, MC3000 contains a higher proportion of heavy solvents, allowing it to remain fluid longer and penetrate deeply into dense surfaces. This results in a strong, cohesive bond that stabilizes the foundation and prevents premature road failure.
Because of its high viscosity, MC3000 forms a thick bituminous film after curing. This film improves:
Adhesion between base and asphalt
Moisture resistance
Load distribution
Surface durability under dynamic traffic loads
These properties make MC3000 one of the most reliable choices for heavy duty construction, offering a level of performance that lighter grades cannot match.
Why Engineers Prefer Bitumen Medium Curing 3000
Choosing bitumen MC3000 offers several advantages that align with modern infrastructure needs.
1. Deep Penetration for Strong Foundations
Engineering teams require bitumen that can seep into the granular base before curing. MC3000 cutback bitumen stays workable long enough to achieve deeper penetration, which strengthens the road’s structure and extends its lifespan.
2. Slow Curing for Better Workability
In warm climates, lighter cutback grades cure too fast, leaving uneven films. MC3000 cures slowly, giving more working time and ensuring uniform coverage across wide areas.
3. Excellent Performance on Sloped Surfaces
Because MC3000 is dense and thick, it does not run off quickly when applied on inclined roads or mountain routes. It maintains a stable layer that adheres strongly and evenly.
4. Ambient-Temperature Application
MC3000 can often be applied without heating, reducing fuel costs, equipment needs, and safety risks at the job site.
5. Long-Lasting Binding Strength
Once the solvent evaporates, MC3000 leaves behind a durable bitumen film that enhances structural integrity and prevents asphalt-base separation.

Applications of Bitumen MC3000
Bitumen MC3000 is designed for heavy duty and long term pavement systems, making it suitable for the following applications:
Prime Coating (MC3000 Prime Coat)
MC3000 is ideal for prime coating because it penetrates the base and provides a strong bonding surface for subsequent asphalt layers.
High-Traffic Road Construction
Highways, expressways, and heavy-load routes benefit from MC3000 due to its strong adhesive performance.
Airport Runways & Taxiways
Runways require binders that withstand extreme pressure and continuous load variations. MC3000 meets these demands perfectly.
Industrial Pavements
Factories, ports, and logistics centers rely on MC3000 for shock-resistant and durable surfacing.
Hot-Climate Road Projects
In hot regions, rapid solvent evaporation can ruin lighter grades. MC3000 remains stable and predictable.
Sloped or Irregular Surfaces
MC3000’s viscosity prevents sagging or runoff, making it suitable for mountain roads and inclined terrains.
How Bitumen MC3000 Works in the Field
When applied to a prepared base layer, Medium Curing 3000 bitumen penetrates into the granular structure. Over time, the solvent evaporates, leaving behind a thick, sticky bitumen coating that:
Strengthens the base
Prevents dusting
Improves adhesion
Enhances pavement durability
Reduces risk of layer separation
This process results in a highly stable foundation capable of supporting heavy asphalt layers and long-term traffic loads.

Q1:What is bitumen MC3000 used for?
Bitumen MC3000 is a medium-curing cutback bitumen with very high viscosity, commonly used in heavy-duty road construction such as highways, airport runways, and industrial pavements. Its slow curing time ensures deep penetration and a thick, adhesive bituminous film between base layers and asphalt coatings.
Q2:How does bitumen MC3000 differ from lighter cutback grades like MC250 or MC800?
Bitumen MC3000 has significantly higher viscosity (3000–6000 cSt) than MC250 (250–500 cSt) or MC800 (800–1600 cSt), yielding stronger bonding and longer working time. This thicker consistency makes it ideal for challenging applications with coarse or absorbent base layers.
Q3:What are the main technical properties of bitumen MC3000?
Bitumen MC3000 exhibits a kinematic viscosity of 3000–6000 cSt at 60 °C, a minimum flash point of around 38–66 °C, at least 55 % residue by distillation, penetration between 100–250 dmm, ductility of at least 100 cm, and solubility above 99 % in TCE.
