When they went to remove the old asphalt, they discovered that
there was a second layer of asphalt underneath.

So they were really removing the *new* asphalt, not the old, right?

Had the orginal driveway settled a lot, even if it hadn't cracked? Why
was there a second layer on top, if there was nothing wrong with the
one below?

A good asphalt job will always have two layers on top of the stone base.
A coarse binder followed by a fine top layer.

But the OP didn't give any details so who knows?- Hide quoted text -

This is why I SEAL my driveway every couple years, the coating seals
the cracks and keeps water from penetrating causing more cracks.

my driveway isnt brand new but thats OK since its about 25 years old
