Bitumen RC30

Bitumen Cutback RC30

Meaning of Cutback Bitumen RC30

Cutback bitumen RC30 is a type of asphalt cement mixed with a solvent or distillate to make it liquid at ambient temperatures, enhancing its coating properties on aggregates.

Properties of Cutback Bitumen RC-30

RC-30 exhibits specific properties crucial for construction projects.

Distillate Content and Types

It can contain between 12 and 40 percent distillate, with various types of solvents such as kerosene, white spirit, gasoline, and naphtha used in its composition.

Environmental Impact

The high demand for distillates in energy applications and air quality regulations have led to a decline in the use of cutback asphalt, including RC-30, in construction.

Rapid Curing (RC) Asphalt

When gasoline or naphtha is used to flux asphalt cement, it results in rapid curing (RC) cutback asphalt like RC-30, which permits up to 45 percent distillate in manufacturing.

Uses of Cutback Bitumen RC-30

It has various applications in construction projects.

Penetrating Prime Coats

It is used for penetrating prime coats on surfaces, enhancing adhesion and durability.

Production of Patching Mixtures

It is utilized in producing patching or stockpile mixtures for repairing asphalt surfaces.

Packing and Safety Measures

Details regarding the packaging of RC-30 and essential safety precautions are outlined.

Packaging Details

RC-30 is packaged in bulk tankers, new steel drums on pallets, to prevent leaks and ensure safe transportation.

Safety Precautions

Safety data sheets should be consulted before use, and precautions such as eliminating ignition sources, wearing appropriate PPE, and avoiding skin contact or breathing vapors must be followed.
