1724 SF x 2/12
287 cubic feet.
Divide by 27 (cubic feet/yard)
Rounds up to 11 cubic yards.
Times 1.25
Rounds up to 14 tons.

A large tandem axle dump hauls 10-12 cubic yards. It is usually
loaded with 15 ton, at least here. Check your information on a
truck hauling 20-26 ton unless you're talking about a semi end or
belly dump. Be careful where you go with trucks this heavy.

#57 stone is close to 1 1/2" diameter down to 1/2", a blend of
ASTM #5 and #7. It is an excellent material for drainage work,
septic, etc. At 2" thick it will only be one stone thick in many
places and there will not be much interlock, a necessity if you
are paving a drive or similar. You will probably need a thicker
bed of coarse stone under the 57 and/or geotextile. It will
probably require a cap of crusher run or screenings for a good
driving surface. You've not ever said what you were planning to
do with 2" of gravel.

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
