My (US) state DOT paved over the concrete highways with rubberized asphalt for similar reasons. The asphalt doesn’t last as long, but it’s quieter and cheaper than concrete repairs. It’s also something that uses up old tires.

Yeah, rubberized asphalt is pretty much standard in Europe, and it's awesome :) The stuff in Germany parent mentioned is next gen even quieter.

It releases nano particles, not great for breathing.
