What is the difference between Bitumen and Tar?
There are some differences between Bitumen and Tar. They include the following.
Bitumen is primarily composed of aromatic hydrocarbons associated with oil deposits. Tar, on the other hand, can form in association with oil or it can be formed from wood.
Bitumen can occur in solid form or as a dark viscous liquid whereas Tar is chemically distinct and occurs primarily as a viscous liquid.
Bitumen occurs naturally and can be prospected from the ground whereas tar is usually produced through distillation.
