Used this stuff on my driveway when I first built the house (15 years now ) ands it’s still fine , no touch ups required as yet ... Driveway was river sand base (dredged from the Miss. river , 2 blocks away , but not by me of course... 
) , highway mat ( heavy woven plastic), and washout over that ... The neighbors used limestone and no mat (prettier) , but theirs has to be re-done most every years .... about 4-5 times as much $ as this stuff 
... I never was much one for “appearance” , just what worked ... 
Not trying to impress anyone in the woods with my driveway . 
It was my slab contractor that put me on to this , taking me to his house , showing me his 25 year old driveway .... still solid ... no ruts ... so I did the same ...
So Glad i did ... 
Going to get a shower , lay down on the reclining platform that faces the constellation Andromeda , and have a few Cold ones ... 
... 
That part elevated above ground level so water quickly runs off ... no mosquito pools underneath .. The only thing wer have to worry about now is those darn mud daubers, who insist on making mud nests on the bottom of the floor ..... we’ll see how they like the black nasty stuff there now ...
