John Loudon McAdam, a Scottish road building expert, is credited with being the first to build tar surfaced roads. That is why they are called macadam roads.
Road tar is made from coal. Asphalt is a heavy fraction of petroleum.

Tar and sand are applied to a road to create a seal coat that helps protect the road surface from moisture, UV rays, and traffic wear. The tar acts as a binder to hold the sand in place and improve traction for vehicles. This treatment helps extend the life of the road and improve safety for drivers.

Yes, road tar can dissolve in gasoline. Gasoline is a powerful solvent that can break down and dissolve various substances, including tar. This property can be useful for removing tar stains or residue from surfaces using gasoline as a solvent.
Tar has been used by humans for thousands of years, with evidence of its use dating back to ancient civilizations. It is derived from the distillation of organic materials like wood or coal. However, the exact date of when tar was first invented is not clearly documented.
