Difference between cut-back bitumen and emulsion bitumen?
cut black bitumen needs a solvent to dilute it whereas emulsion doesn't.

What is difference between bituminous coal and bitumen?
Bitumen is a highly viscous product of the decomposition of algae and other organisms deep underground. Bituminous coal is the solid product of the lithification of mostly plant remains by overburden pressure.
What is cut-back bitumen?
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.
What color is bitumen compared to smaller hydrocarbons?
Bitumen is typically black or dark brown in color compared to smaller hydrocarbons, which are often colorless or light in color. This difference in color is due to the higher molecular weight and complexity of bitumen compared to smaller hydrocarbons.
What is the difference between Tar and Bitumen?
Petroleum bitumen is often confused with tar. Although bitumen and coal tar are similarly black and sticky, they are distinctly different substances in origin, chemical composition and in their properties. Coal tar is produced by heating coal to extremely high temperatures and is a by-product of gas and coke production. It was widely used as the binding agent in road asphalt in the early part of the last century, but has since been replaced by refined bitumen.
What is the difference between penetration and softening point of a bitumen?
The penetration point of Bitumens such as asphalt is the depth in tenths of millimeters a standard weighted needle will penetrate through a given sample of asphalt at a given time and temperature. The softening point of Bitumen such as asphalt is the temperature at which the Bitumen softens at standard conditions. Method of detrmination employs a ball and ring in which the ball falls through the ring after the softening has been reached.
