Tarnafta

Tarnafta is a term that refers to a type of tar used in the production of asphalt and road surfacing. It is derived from the distillation of coal tar, a byproduct of the coal industry. The term "tarnafta" is often used interchangeably with "coal tar pitch," although the specific composition and properties can vary depending on the source and processing methods.

The primary component of tarnafta is bitumen, a highly viscous, black, and sticky substance. This bitumen is extracted through a process that involves heating coal tar to high temperatures, which separates the bitumen from other components. The resulting tarnafta is then used in various applications, including the production of asphalt for roads, roofs, and other construction purposes.

One of the key advantages of tarnafta is its durability and resistance to weathering. When used in road surfacing, tarnafta-based asphalt can withstand heavy traffic and harsh environmental conditions, making it a popular choice for infrastructure projects. Additionally, tarnafta is relatively inexpensive compared to other types of asphalt, which contributes to its widespread use.

However, the production and use of tarnafta are not without environmental and health concerns. The distillation process can release harmful pollutants into the air, and the use of coal tar in construction materials can contribute to soil and water contamination. As a result, there is ongoing research and development focused on finding more sustainable alternatives to traditional tarnafta-based products.
