Salt on gravel driveway

I've got a long, steep, gravel driveway leading up to my house.

Over the last few weeks we've had a small amount of snow each day and we've been driving up and down the driveway. Occasionally, I'll throw down some gravel near the top to help with traction on my wife's front wheel drive car. With a small amount of snow falling each day, and us driving up and down the driveway, it slowly compacts but still is quite drivable.

When I get it plowed, my plow guy throws down a mix of salt and aggregate. The problem is that the salt turns the whole driveway into mush afterwards. Even though it's just an inch or so of mush, it's quite hard to drive on and the tires leave ruts that eventually freeze.

The other problem is that my propane delivery truck basically refuses to drive on anything other than bare gravel, which seems a fairly unrealistic standard for VT winters.

Alaskans and Scandinavians basically just use gravel and it seems to work fine there. It seems that unless I have a truck putting down salt every day, the driveway is going to have a layer of compacted snow on it.

What are your thoughts on skipping the salt portion and just using gravel after a plow?
