CutBack Bitumen
Performance Grade Bitumen
Cutback Bitumen is a type of asphalt binder produced by blending conventional bitumen with selected petroleum solvents to reduce its viscosity and improve handling and application at lower temperatures. This characteristic makes cutback grades suitable for specific road construction, maintenance, and asphalt applications where conventional hot-applied bitumen may not be the preferred option. This allows the bitumen to be used without heating in certain construction conditions.
It is commonly used for surface dressing, prime coating, and cold weather road applications. Cutback bitumen grades such as RC, MC, and SC are manufactured in accordance with ASTM D2027, ensuring reliable performance and proper curing through solvent evaporation.
What Is Cutback Bitumen?
This binder is manufactured by adding a petroleum-based solvent to penetration grade bitumen. The solvent temporarily reduces the viscosity of the binder, allowing it to be applied more easily at relatively lower temperatures.
Cutback Bitumen Grades
Products are generally classified according to their curing rate and viscosity. The main categories include:
Rapid Curing (RC)
Rapid-curing grades use relatively volatile solvents and are designed to cure quickly after application. They may be used in specific surface treatment and road maintenance applications.
Medium Curing (MC)
Medium Curing Cutback Bitumen uses solvents with a slower evaporation rate than RC grades. MC grades are commonly considered for applications where controlled curing and workability are required.
Slow Curing (SC)
Slow-curing grades use less volatile oils and solvents, resulting in a slower curing process. Their use depends on project requirements, climate, and the specified application method.
Bitumen CutBack MC30
A low viscosity cutback grade designed for excellent penetration and surface preparation in roadworks. Bitumen cutback MC30 is widely used for prime coating, helping improve adhesion between granular bases and asphalt layers.
Bitumen CutBack MC70
A medium curing cutback grade offering balanced penetration and binding performance for road applications. Bitumen cutback MC70 is commonly used for prime coating, surface treatment and pavement works requiring controlled curing characteristics.
Bitumen CutBack MC250
A higher viscosity cutback grade providing strong binding and coating performance for demanding road applications. Bitumen cutback MC250 is commonly used for surface treatments, patching and asphalt works requiring greater residual binder strength.
Applications of Cutback Bitumen
Depending on the grade and project requirements, cutback asphalt binders can be used in several road construction and maintenance applications, including:
- Road surface treatment
- Prime coating
- Tack coating
- Asphalt pavement maintenance
- Surface dressing
- Road repairs and maintenance
- Waterproofing applications
- Certain cold-mix asphalt applications
The appropriate grade should be selected according to the climate, pavement design, traffic conditions, application method, and applicable technical specifications.
Cutback Bitumen vs. Penetration Grade Bitumen
The main difference is viscosity and application method. Penetration Grade Bitumen is generally heated before application to achieve the required working viscosity, while cutback products contain a solvent that temporarily reduces viscosity.
Once applied, the solvent evaporates and the remaining binder develops its intended properties.
Therefore, choosing between penetration grade and cutback products depends on the project specifications, application temperature, equipment, environmental requirements, and local standards.

What is Cutback Bitumen?
This products is an asphalt binder produced by blending conventional bitumen with selected petroleum-based solvents. The solvent temporarily reduces viscosity, making the material easier to handle and apply at lower temperatures.
What are the main types of this product?
The main categories are Rapid Curing (RC), Medium Curing (MC), and Slow Curing (SC). They are classified according to the type of solvent used and the rate at which it evaporates after application.
What is MC grade used for?
Medium Curing (MC) grades are commonly used in road construction and maintenance applications where good workability and controlled curing are required. The appropriate grade depends on the project specifications and application method.
What is the difference between RC, MC, and SC grades?
The main difference is their curing rate. RC grades cure relatively quickly, MC grades have a medium curing rate, while SC grades cure more slowly. Selection depends on the application, climate, and technical requirements.
