TEAR UP THE OLD DRIVEWAY! The 700 buck job is just a waste of money

Assuming no major water problem fill is done settling after 7 years.
How old is your current driveway?

Laying new asphalt on old thats unstable will just fail again in a year
or two.

a good friend tried the cheap way and regretted it the next year when
it failed again, plus tearing out a double layer drivway will cost
more.

if you want to throw away 700 bucks please toss it my way

the key to a good long lived ashalt driveway is a good well drained
gravel base.
