By pavement do you mean concrete, asphalt, or something else?

Concrete on the road does sit for a long period of time before they allow traffic on it, same as your driveway. Concrete is the main structural part, sitting on top of the aggregate, and must be sufficiently cured before it can handle weight. Your driveway is far thinner than the road and needs to be cured completely before heavy weight can sit in place for hours to avoid cracking, and it doesn’t cost the company that poured it more to let it sit without being used so they are going to error on the side of longer. A road tends to have pressures from traffic needs that will lead to it being on the shorter end of the time estimates.

Asphalt (aka blacktop) only takes a day or two because it doesn’t require as long to cure and it is a lot more flexible than concrete so it isn’t as in danger of cracking right away.
