tarmac

Tarmac is a special kind of pavement made from tar and other materials. It's often used for building runways at airports.

You might have heard of tarmacs before - they're those smooth black surfaces that airplanes land on when you arrive at an airport. Tarmacs are really important because they help planes take off and land safely, even in bad weather. Some people think of the word "tarmac" as just another name for asphalt, but technically it's a bit different - tarmac is made from a mixture of tar, stones, and other materials that gives it a special texture and durability. You can also see tarmacs at other places like parking lots or highway shoulders, where they help keep cars safe on the road.
