The invention of tar roads and pavements is attributed to Scottish engineer John Loudon McAdam in the early 19th century. He developed a method known as "macadamization," which involved layering crushed stone and gravel to create a durable road surface. The use of tar as a binding agent was later popularized by Charles Macadam and others, enhancing the durability and smoothness of the roads. This innovation laid the foundation for modern road construction techniques.
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.

Around 1820 John Loudon McAdam invented a way to make roads which became known as macadamisation. When motor vehicles arrived the macadamised roads became very dusty and so they were sprayed with a layer of tar to seal the road surface. This was known as tarmac.

Tarmac, short for tarmacadam, was patented in the 19th century by Scottish engineer John Loudon McAdam. It is a road surfacing material made of crushed stone mixed with tar or bitumen, primarily used for surfacing roads and pavements.
Roman pavements and roads are made of flat stones on top of each over that slope at either side to let rain water drain off. pavements and roads were often laid on foundations like clay chalk and gravel.

yes it is. it is one of many substances in a cigarette.
In 1824, people first used tar on road construction. It was occurred in Paris, where people place tar blocks on Champs-ÌälysÌ©es of Paris. The modern tar roads are result from two Scottish engineers.
if we take one cigarette. You get this much Tar.
