Why are most runways made of asphalt and not concrete?

The runways at Frankfurt Airport are asphalt (old satellite imagery shows that they were concrete before), and the airport handles plenty of Superjumbos, the Airbus A380, so it's not a matter of handling heavy planes. All runways in big airports, even those covered in asphalt, have reinforced concrete foundations that vary in depth.

What Are The Differences Between Concrete And Asphalt Runways?

Similarly, other runways have concrete installed on top of asphalt as the latter functions as a strong base that minimizes concrete's cracking risk. These are deepest in areas that are subjected to more pressure, such as the ends of runways where …

Also from the pilots perspective, not thinking about the calculations, it is not a real difference. Maybe asphalt runways are a little more prone to have standing water on it if they are not groved then concrete runways and also tend more to get cracks. Airports will have their reasons why they decide for one of these types of runway.
