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.
if we take one cigarette. You get this much Tar.
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.
