I will address your question on a base.
We very recently put in a new drive on sandy loam. We had seen previous posts on this forum suggesting "Milage" or "Millage" (not sure of the spelling) for use under an RV port. We suggested using this with the excavator. It was not a hard sell because he used it for his roadways of a campgrounds he owns. He excavated approx 6" down, put down the millage and then rolled it. It came our beautifully. No dust, no ruts, an no need to seal it.
Millage or milage is a recycled blacktop from road reconstruction that has been ground up. It is pea stone with asphalt as opposed to asphalt covering limestone. It has similar texture to limestone gravel, but is obviously black. The cost was slightly more expensive than quarry gravel (because of trucking distance), but much cheaper than asphalt or concrete. Several guys on the crew have used it on their own properties and raved about it. The new drive abuts a concrete drive and there is no black tracking marks onto the concrete. For those of you that mentioned it previously, a sincere thanks.
