I didn't know there was a difference between the two!
> Asphalt is a mixture of aggregates and bitumen that needs up to two days before it completely cures. Whereas, Tarmac is a combination of crushed stone and tar that cures quickly.

- senkora 4y agoFrom your link I learned that tarmac is short for tarmacadam, named after John Macadam, who is also the name-origin for macadamia nuts. https://en.m.wikipedia.org/wiki/John_Macadam https://en.m.wikipedia.org/wiki/John_Macadam
- the_jeremy 4y agoThat is incorrect. John McAdam[0] has the name for tarmac, while John Macadam[1] has the name for macadamia nuts. 0: https://en.wikipedia.org/wiki/John_Loudon_McAdam https://en.wikipedia.org/wiki/John_Loudon_McAdam 1: https://en.m.wikipedia.org/wiki/John_Macadam https://en.m.wikipedia.org/wiki/John_Macadam
- senkora 4y agoThanks for the correction! I can no longer edit my comment but you are right.
- touisteur 4y agoAnd there's a name that became a French word there: macadam https://fr.m.wikipedia.org/wiki/Macadam_(route) https://fr.m.wikipedia.org/wiki/Macadam_(route). Thank you both parent and GP for the history/etymology lesson.
- JoeAltmaier 4y agoInteresting! I often wondered while sitting on a runway, if tarmac was so good, why don't we get any? It's just at airports!
- selectodude 4y agoStrangely, you don't sit on Tarmac, even on a runway. Airport ramps, aprons and most busier runways are paved with high strength concrete.
