Cut-back bitumen is a type of bitumen (asphalt) that has been diluted or cut back with a volatile solvent or oil, making it easier to work with at lower temperatures. The solvent evaporates after application, leaving behind a solid bituminous material. Cut-back bitumen is commonly used in road construction and maintenance for surface treatments and prime coating.
Typically, bitumen and "asphalt" are interchangeable.
'asphalt' refers to a mixture of mineral aggregate and bitumen (bitumen)is the black liquid which is extracted from the crude oil....
Straight run bitumen is a bitumen obtained by the fractional distillation of crude oil without undergoing further modifications. It is typically used as a binder in road construction and waterproofing applications. Straight run bitumen has higher viscosity and lower penetration compared to other types of bitumen.
Bitumen is a petroleum tar, known as asphalt, pitch, or blacktop.
Bitumen grade is a classification system based on the viscosity of the bitumen. A higher bitumen grade indicates a lower viscosity, meaning it is more viscous and suitable for higher temperature environments or heavy-duty applications.
Cut-back bitumen uses solvent as the mixing medium where in Emulsion uses water to dilute bitumen for the purpose of tack-coating / road works
The density of cutback bitumen MC 30 at 20 degrees Celsius is typically around 1.0 grams per cubic centimeter. This may vary slightly depending on the specific formulation and manufacturer of the bitumen.
Cutback Bitumen : Normal practice is to heat bitumen to reduce its viscosity. In some situations preference is given to use liquid binders such as cutback bitumen. In cutback bitumen suitable solvent is used to lower the viscosity of the bitumen. From the environmental point of view also cutback bitumen is preferred. The solvent from the bituminous material will evaporate and the bitumen will bind the aggregate. Cutback bitumen is used for cold weather bituminous road construction and maintenance. The distillates used for preparation of cutback bitumen are naphtha, kerosene, diesel oil, and furnace oil. There are different types of cutback bitumen like rapid curing (RC), medium curing (MC), and slow curing (SC). RC is recommended for surface dressing and patchwork. MC is recommended for premix with less quantity of fine aggregates. SC is used for premix with appreciable quantity of fine aggregates.Bitumen Emulsion : Bitumen emulsion is a liquid product in which bitumen is suspended in a finely divided condition in an aqueous medium and stabilized by suitable material. Normally cationic type emulsions are used in India. The bitumen content in the emulsion is around 60% and the remaining is water. When the emulsion is applied on the road it breaks down resulting in release of water and the mix starts to set. The time of setting depends upon the grade of bitumen. The viscosity of bituminous emulsions can be measured as per IS: 8887-1995. Three types of bituminous emulsions are available, which are Rapid setting (RS), Medium setting (MS), and Slow setting (SC). Bitumen emulsions are ideal binders for hill road construction. Where heating of bitumen or aggregates are difficult. Rapid setting emulsions are used for surface dressing work. Medium setting emulsions are preferred for premix jobs and patch repairs work. Slow setting emulsions are preferred in rainy season.

why bitumen is used
Mustek manufactures a variety of packed bitumen products. Their bitumen products are produced at the Europoort refinery in Rotterdam, Germany. They produce 3 types of bitumen: penetration bitumen,oxidized bitumen, and hard bitumen.
Bitumen is use as fuel.
Typically, bitumen and "asphalt" are interchangeable.
