Why do we still use concrete and asphalt for our roadways? Why have we not found a better material that is less prone to potholes and always feels smooth to drive on?

An asphalt roadway can be immune to potholes and last a very long time. Look at the Autobahn. It is 29 inches thick. In the US they normally only do 8 inches to save cost in the short term.(i think that measurement included the base)
