Cutback Bitumen

Quick Answer

Cutback Bitumen is a petroleum-based bituminous binder produced by blending penetration-grade bitumen with volatile petroleum solvents such as kerosene, diesel, or naphtha to temporarily reduce its viscosity. This allows the bitumen to be applied at lower temperatures without extensive heating, making it ideal for road construction, prime coats, surface dressing, road maintenance, cold weather paving, and asphalt repair projects.

As a leading Cutback Bitumen supplier in Pakistan, SHM TRADE GLOBAL supplies premium-quality SC (Slow Curing), MC (Medium Curing), and RC (Rapid Curing) Cutback Bitumen grades for contractors, infrastructure developers, government projects, and international buyers.

What Is Cutback Bitumen?

Cutback Bitumen is a specially formulated asphalt binder in which petroleum solvents are added to penetration-grade bitumen to reduce its viscosity. Unlike conventional hot bitumen, Cutback Bitumen can be sprayed or applied at significantly lower temperatures, improving handling and simplifying construction in cooler climates or locations where heating equipment is limited.

Once applied, the solvent gradually evaporates, leaving behind a durable bitumen film that provides strong adhesion, waterproofing, and long-lasting pavement protection.

Because of its ease of application and excellent bonding characteristics, Cutback Bitumen is widely used in road construction, pavement preservation, asphalt repair, and infrastructure maintenance projects.

How Is Cutback Bitumen Manufactured?

The manufacturing process begins with high-quality penetration-grade bitumen. Carefully selected petroleum solvents are blended into the hot bitumen under controlled conditions to temporarily reduce viscosity without compromising the final performance of the binder.

After application, the solvent evaporates at a controlled rate depending on the curing grade, leaving a durable bitumen layer that bonds effectively with aggregates and pavement surfaces.

This controlled curing process makes Cutback Bitumen highly effective for projects requiring excellent penetration, surface bonding, and waterproof protection.

Types of Cutback Bitumen

Cutback Bitumen is classified according to the rate at which the solvent evaporates.

Rapid Curing (RC) Cutback Bitumen

Rapid Curing Bitumen contains highly volatile solvents that evaporate quickly after application, allowing the bitumen to harden rapidly.

Available Grades

• RC-30
• RC-70
• RC-250
• RC-800
• RC-3000

Common Applications

• Surface dressing
• Spray sealing
• Chip sealing
• Road patching
• Emergency pavement repairs

Medium Curing (MC) Cutback Bitumen

Medium Curing Bitumen uses medium-volatility solvents that provide additional working time before curing.

Available Grades

• MC-30
• MC-70
• MC-250
• MC-800
• MC-3000

Common Applications

• Prime coats
• Cold mix asphalt
• Pavement rehabilitation
• Road maintenance
• Base stabilization

Slow Curing (SC) Cutback Bitumen

Slow Curing Bitumen contains lower-volatility oils that evaporate gradually, allowing deeper penetration into pavement surfaces.

Available Grades

• SC-30
• SC-70
• SC-250
• SC-800
• SC-3000

Common Applications

• Prime coating
• Soil stabilization
• Dust control
• Surface penetration
• Low-temperature paving
