- Bitumen: Petroleum product obtained by distillation of petroleum crude.
- Cut Back Bitumen: Viscosity reduced by volatile dilutant after cutback is mixed with other aggregates, the volatile gets evaporated and cutback develops binding properties.
- Emulsion: Liquid product in which a substantial amount of bitumen is suspended in the finely divided condition in an aqueous medium. Function of the emulsifier is to protective coatings around the globules of the binder.
- Tar:Obtained when natural organic materials such as wood and coal destructively distilled in the absence of air. Coal tar is superior to wood tar.

Introduction:
Bitumen is a black, sticky and highly viscous material that is used as a binder in road construction and waterproofing applications. It is derived from petroleum and has a wide range of viscosities depending on its application. In order to reduce the viscosity of bitumen and make it more workable, a volatile dilutant can be added. This process is known as cutback bitumen.
Cutback Bitumen:
Cutback bitumen refers to bitumen that has been diluted with a volatile solvent or dilutant. This process is used to decrease the viscosity of bitumen and make it easier to handle and apply. The dilutant used can be a wide range of volatile solvents, such as gasoline, kerosene, or naphtha.
Cutback bitumen is commonly used in road construction for applications such as prime coats, tack coats, and seal coats. It offers several advantages over neat bitumen, including improved workability, easier mixing and application, and faster curing times.
Types of Cutback Bitumen:
There are different types of cutback bitumen based on the volatility of the dilutant used. The specific type of cutback bitumen is designated by a code, which indicates the viscosity and volatility of the cutback.
One common classification system for cutback bitumen is based on the rate at which the dilutant evaporates. The different types of cutback bitumen based on volatility are:
1. Rapid-Curing (RC): Rapid-curing cutback bitumen has a high volatility dilutant, which evaporates quickly after application. It is used for surface treatments and cold weather applications where quick curing is important.
2. Medium-Curing (MC): Medium-curing cutback bitumen has a moderate volatility dilutant. It is used for prime coats, tack coats, and seal coats in moderate weather conditions.
3. Slow-Curing (SC): Slow-curing cutback bitumen has a low volatility dilutant, which evaporates slowly after application. It is used for prime coats, tack coats, and seal coats in hot weather conditions.
Conclusion:
Cutback bitumen is a type of bitumen that has been diluted with a volatile dilutant to decrease its viscosity. It offers improved workability and easier application compared to neat bitumen. The specific type of cutback bitumen is determined by the volatility of the dilutant used, with rapid-curing, medium-curing, and slow-curing being common classifications. Cutback bitumen is widely used in road construction for various applications such as prime coats, tack coats, and seal coats.
