Ok, to clarify what I am doing. I need to put what is called 57's ( I
think it is 3/4" limestone) over a 1724 square foot area at least 2"
thick. How much would I need? Approx 15 ton? 20 ton?

I am thinking of ordering a full truck load that holds approx. 20-26
tons of weight. If I have extra, I guess I could use it somewhere on
the gravel drive. right? Or do I need more?

TIA

Hank
