Okay, as Larry has seen, I have a 150 foot gravel driveway, with a 25 X 75 foot parking pad at the end of it. It's gravel - a mix of 'pea' stone and 1/2~3/4 crushed. Right now, it needs 'topped up' with about five yards of fresh pea stone.
My real problem, though is frost heave. With last week's thaw, I have about a 4" high heave, and it's so soft that the cars sink in about 4" just driving over it. Heck, I sink in almost to my shoe tops in places.
It froze again over night, and hasn't thawed enough today to be able to work with it. I had planned on using the lawn tractor and roller to press it back down (I do this three or four times every Spring.), but will have to wait until the next thaw cycle for that.
My main problem here is that the underlying soil is nasty yellow clay that holds the water and make a sticky, glue-like mess under the gravel, and that's what is causing the heave.
I think the only way I'd be able to successfully pave mine (asphalt, BTW) would be to excavate about 1½~2 feet and backfill with decreasingly sized stone - like 2~4" goonies, then 1~2 crush, then 3/4" crush - before topping it with several inches of asphalt. All that seems very labor intensive, and also very expensive.
So, any advice or suggestions?
