As to periodic sealing, though, recall highway departments have the
constraint of needing to accomodate traffic nearly constantly whatever
they do (aside from a totally new road). So what they do or do not do
may be quite different from what a homeowner does or does not do with
his driveway.

Traffic interruption is not a factor. They just know that benefits are
minimal to non-existent, and costs are significant.

Commercial parking lots are coated to keep them pretty, not make them last
longer. All those oil stains don't impress the customers well.

You're not in the northeast, are you.
