Why Does Pavement Need to Be Flexible?

You'd think that pavement would need to be very strong and sturdy to withstand everything it goes through. It does have to be strong and sturdy, but it does not have to be rigid and unmoving, as "strong" and "sturdy" often imply. Pavement fares better when it's flexible, as asphalt often is. Bitumen is a component of asphalt, and a newer process known as foamed bitumen stabilisation appears to hold the answer to the question of how to make pavement very strong without compromising on its flexibility.
