Difference between asphalt, bitumen, and tar./What is asphalt, bitumen, and tar?

   Asphalt, bitumen, and tar are defined below.

Asphalt road


It has two basic ingredients. Stone aggregates, sand, and gravel form the first part with a 95% share and 5% of bitumen as the other part. Here, bitumen is the binder material, which holds together all the ingredients. 
The primary use of asphalt is in road construction. They are manufactured in hot mix plants at a specific temperature. In America, & some parts of Europe, asphalt also refers to bitumen.



It is a black viscous liquid, which is used as a binder material in making asphalt. It is a hydrocarbon, obtained naturally or as a residue in the distillation of petroleum.
 Bitumen is used in making paints, roofing materials, etc. other than road works.


Coal tar

 It is the thick black liquid produced by the destructive distillation of coal. In the process of manufacturing coke and coal gas from coal, tar is produced as a by-product.
 Used in making paints, synthetic dyes, and in manufacturing medicines related to skin symptoms. Since it is carcinogenic in nature, its usage is limited in making tar roads.
