You can make runways out of concrete.

But then you have to close the runway for extended periods for repair. The beauty of tarmac is that it cures quickly.

Most runways, at least at busier airports, are already concrete.

I'm not sure that's true? Maybe it depends on the location but LHR is asphalt, CDG is asphalt, AMS is asphalt, YYZ is asphalt... Only when you look at hotter climates do concrete runways appear common.

I think only in moderate climates. Concrete tends to crack when it gets really cold and then warm.

We've got concrete runways here at MSP (Minneapolis/St. Paul). A lot of the highways are concrete as well.
