Cutback Bitumen MC-30 is a medium-curing (MC) asphalt product produced by dissolving penetration grade bitumen in a petroleum solvent such as kerosene. The addition of the solvent temporarily reduces the viscosity of the bitumen, allowing easy handling, spraying, and application at ambient temperatures.

After application, the solvent gradually evaporates, leaving a durable bituminous residue that effectively binds aggregates and seals surfaces.

What Is Cutback Bitumen MC-30?

MC-30 is a medium-curing cutback asphalt designed primarily for road construction and maintenance applications. It consists of asphalt cement blended with a medium-volatility diluent, enabling deep penetration into granular surfaces before curing.

This controlled curing behavior makes MC-30 particularly suitable for prime coating and cold application processes.

Main Applications

Cutback Bitumen MC-30 is commonly used for:

• Prime coat on granular base courses

• Road maintenance and rehabilitation works

• Penetrating treatments prior to asphalt surfacing

• Cold-applied waterproofing applications

• Sealing capillary voids in mineral surfaces

• Bonding loose aggregates and surface particles

Application is typically performed by spray distributors, ensuring uniform coverage and effective penetration.

Key Advantages

• Medium curing rate for controlled penetration

• Excellent adhesion to mineral aggregates

• Easy application without heating or thinning

• Suitable for cold weather conditions

• Effective binding between base course and asphalt layers

• Reduces dust and surface permeability

Handling & Storage

• Store and transport at the lowest practical temperature

• Keep containers tightly sealed

• Store away from direct heat and ignition sources

• Drums should be placed on pallets to prevent leakage

Packaging Options

• Bulk supply via tanker trucks

• New steel drums with secure sealing

• Palletized packaging for safe transport and storage

Safety Precautions

• Refer to Safety Data Sheet (SDS) before use

• Avoid inhalation of vapors

• Prevent skin contact

• Eliminate all ignition sources during application

• Use appropriate personal protective equipment (PPE)

• Do not discharge product or residues into sewer or stormwater systems

Compliance & Standard

Cutback Bitumen MC-30 is manufactured in compliance with ASTM D2028-97 (Reapproved 2004) for medium-curing cutback asphalts used in pavement construction and treatment.
