The gravel clay mix forms a base for the crushed limestone [ we call it Afton stone up here ]. The layer of Afton does not let any water get down into the clay mix. But it generally does not develop pot holes in a light driveway use.
JerryK,
Seems like every region of the country has different "names" for the same stuff. Around here they have what they call "screenings". Looks like it might be your "crushed limestone-Afton". It's about 1/8th inch or less in diameter. Could be mistaken for "pee gravel" if not for the limestone color. Does that sound like your Afton stone?
I have 1/4 mile access road to cover. Already has a good clay & gravel base. Looking for a top dressing to reduce the dust, and add to the stability.
Thanx!
