  • This word seems very American to me. I was fascinated by a film called Two-Lane Blacktop - yes, I'm the kind of person who'll spend 2 hours trying to pin down the meaning of a word - because I have categorically never heard this word in use in Australia.

  • Me neither. I'd probably call the material bitumen. Not sure if there's a one-word equivalent for the verb form, perhaps tar?

  • Also known as asphalt in the U.S., though some asphalt is grayer than blacktop.

  • Tarmac, anyone?

    May 11, 2008

  • Asphalt is used in Australia, but not so much in connection with roads or highways - it's a surface I strongly associate with school playgrounds.

    Tarmac, at least for this Aussie, is exclusively an aviation/airport term, referring to the runway, as in "we hit the tarmac at about 9.30". Oh, I can see, over on tarmac, that resetee has identified tarmac=runway as a British usage dating from 1919.

  • I never knew about the runway usage. Tarmac was what roads were made of where I were brung up.

  • We call it macadam where I grew up, because a man named Macadam supposedly invented it. I remember discussing this previously on Wordie, in the long ago time. (See macadam.)
