Description

Originally a mixture of Slag, Tar, Asphalt, and other materials used in construction of road beds, parking lots, and runways. Tarmac was invented by E. Purnell Hooley in 1901 when he saw a barrel of tar spill on a Macadam roadway. He patented the idea and began selling the product as Tar Macadam. The term 'tarmac' is now commonly used for all asphalt-type roadways.
