Why is tarmac called tarmac?
The “tar-“ part of tarmac comes from the extra layer that a businessman named Edgar Purnell Hooley chose to add to McAdam’s macadamized pavement. As the story goes, Hooley passed a tar factory where he noticed a barrel of the gooey black stuff had tipped over and spilled across the macadamized road. To prevent shoes from sticking in it, the factory had spread gravel on top. This layering of tar and gravel created a sturdy, durable and dust-free roadway. Hooley patented and trademarked “Tarmac” in 1901.
What is tarmac short for?
Tarmac, short for tarmacadam, gets its name from John Loudon McAdam, who first introduced his unique “macadamizing” method in 1820. Macadamizing is a process in which a layer of gravel is adhered to the top of normal pavement, but that isn’t exactly what makes tarmac tarmac.
What is the difference between bitumen and tar?
Tar is a naturally found substance created from natural resources like wood, peat or coal. Bitumen, on the other hand, is formed from petroleum. Asphalt is made when a blend of small pebbles, stones, sand and other filler are mixed with bitumen as a binding agent. The difference between bitmac and the asphalt you know is simply a matter of the amount of sand and filling agents used in the mixture.
When was tarmac invented?
Hooley patented and trademarked “Tarmac” in 1901. Unfortunately, tarmac is easily damaged by gasoline and diesel fuel, so much of the tar in tarmac today has been replaced with a more resistant material called bitumen, thus creating “bitmac.”.

You get tarmacadam when you coat and mix crushed stones with tar. Tar is a dark-brown or black viscous liquid we get from organic materials through a chemical process called destructive distillation.
And What Makes an Asphalt Driveway?
Asphalt is actually another name for bitumen, a highly viscous form of petroleum. When you mix asphalt with crushed stones similar to the ones used in tarmacadam, you get asphalt concrete ‒ a material used to lay large roads, parking lots, and driveways. In day-to-day conversation, we often simplify asphalt concrete to just asphalt.
