Bitumen, also known as asphalt, is a black, sticky, and viscous semi-solid or liquid form oil based substance. It is a semi-solid substance and is stable at ambient temperatures. There are six major kinds of bitumen according to their applications: paving grade bitumen, cutback bitumen, bitumen emulsions, modified bitumen, polymer modified binders and multi-grade bitumen.
The major use of bitumen is in construction industry as a binder involving roofing and paving applications and around 85% of bitumen produced in the world is used for road construction, car parks, airport runways and footways. It is also used as a binding agent to mix sand, gravel and crushed rock. It can also be used for bituminous waterproofing products. Asphalt or Bitumen also is used in paint and marker inks to increase the weather resistance and permanence of the paint and ink, and to make the color much darker.
