All good advice so far but there are more good options.
Definition of terms:
Many folks call crushed limestone gravel. Natural gravel has smooth edges from previous water tumbling action and is NOT the best choice for a firm weatherproof driveway.
Crusher run is crushed rock and contains all sizes down to dust from the size specified on down. It has been screened to remove larger chunks than specified.
Do not use washed (septic) gravel as there are no fines and it is a waste of $.
Shale is a good alternative to crushed limestone. It typically is delivered in larger pieces but even light traffic quickly breaks it down. It ends up looking like blacktop consistency wise but in an attractive blue-grey color. It has less of a dust problem than crusher run limestone. It is lighter per volume so cheaper to haul. I use both but prefer shale, especially near the house.
Recycled asphalt is what is on the drive now. It has broken down over the years and I was a bit muddy last spring......so, I am looking to bring it up to grade and add a mild slope for better run-off.
The other thing is I am not looking to do my entire driveway at this point. Just a couple of sections that "need" to be done.
Will 1" gravel get me through winter and spring.??
We use something similar to "crusher run" here in Connecticut for driveways. It is called process gravel. The most common being 3/4 process which has crushed rocks from 3/4 inches down to dust mixed together. It locks together well after grading it and then driving over it to pack it down.
