On-board microphones capture the noise differential as a vehicle transitions from an asphalt rubber surface (ARFC) to a portland cement concrete pavement (PCCP) and then back to smooth and quiet asphalt.

When it comes down to it, drivability is what makes the road the one you want to take. Asphalt pavements are the best solution when you want high performance. They are smooth, quiet, and safe. They can reduce noise at the point where the tire meets the road, and they are quick and easy to construct and maintain over time. That's drivability.
