In my experience- roughly. I've never been shorted, but I know of 2
local vendors who measure by bucket, rather than actual weight.
Probably a better way to do it as it is the volume, not the weight
that is important for a job. and a week of rain could have you buying
water. [the biggest expense is the carting of it anyway]
no. Ask the place where you're buying for a chart of their
volume/tonnage. It will vary depending on the type of rock, so
there are no hard & fast charts. But a cubic yard=a ton will get you
in a very rough ballpark.
Buy extra and post the leftovers on craigslist if you don't have a
place to store it. I've still got 5 tons of river cobble left from
a 2008 project- but my neighbor and I keep finding uses for it.
Also, BTW- 2" stone won't compact the same, won't shed leaves the
same, and won't provide the same drainage as 3/4" stone. [and round
stone vs crushed throws a couple more variables in.]
What you're using the stone for should help determine what type and
size you want.
Also, keep in mind that you cannot shovel 2" stone, especially crushed
stone. Each time you try you will pick up one, two or three rocks and it
will take forever. You need power equipment.
Also are you talking washed stone with nothing inbetween the stones, or
crusher run/pit run which has fine material between the stones and can be
The spousal unit and I would beg to differ... It did take two weeks, a couple of
small trailer loads a day, but we just moved 13 tons of 2" crushed up a 250'
mountain driveway. Said trailer loaded/unloaded with flat shovels.
A Bobcat would have been nice, but we didn't want to tear up a 1 month old
I dont know the answer to that, BUT, let me tell you something from
past experience : If they tell you they are bringing out half a truck
load of something..*.BEFORE the guys starts pouring it out , jump up
on the truck and look inside the bin to make sure its about half
full. I got royally cheated recently when i paid for a half truck and
got no more than a quarter truck load of crushed limestone .
Gravel, sand, etc are purchased and hauled based on tonnage, not
yardage. A ten yard dump truck (large tandem) will deliver about
15 ton. Most waybills will indicate tons - some are just based on
how full the truck is, others are digital readouts. Digital lets
you pay for the water, volume makes the water less of a factor.
Calculate the cubic volume you need. Normal calculations would be
in cubic yards. Multiply the cubic yard calculation by 1.25 (this
multiplier changes slightly with different materials, but this one
will get you quite close). This will give you the required
Choice 2. Give the supplier your cubic yardage requirement and
have them calculate.

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?

Trying to keep 3/4 stone to a 2" thickness ill be tricky. Is that
compacted, or loose? What will 2" accomplish?
I'd get the full load. It is probably only #12-15 a ton- and
you'll be paying $100+ for delivery. If you can spread it thicker,
do so- but you don't want to be a ton short. That would be an
17.5 tons for 2", but maintaining a consistant 2" depth in that large
area is near impossible. 26 tons would cover it with a better depth of 3".
I'd go at least 24 tons. 26 would be even better.
57's are a great size, as it settles together very nicely just dumped &
raked, virtually no manual compaction required for most applications.
1724 SF x 2/12
287 cubic feet.
Divide by 27 (cubic feet/yard)
Rounds up to 11 cubic yards.
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.

You're right, I never said what I was trying to accomplish. Sorry. I
am building a 36 X 48 pole barn and need a level pad and also a 230'
driveway cut in. The ground slopes down from grade point to almost 3'.
I have had 3 excavators come and give me estimates and got different
opinons on what is best. 2 contractors advised building up with 304's,
then a couple inches of 57's, then 6" of concrete. The other wanted to
fill with # 2's then 304, then 57's, then concrete. All 3 agreed to
use # 2's on the drive as the base. If it makes a difference, I live
in central Ohio. Frost line at about 18-24" I will be parking a
motorhome in it and maybe rent the other side out. Anyway, I wanted to
get others opinions since I know very little, if anything, about the
best way to do this.
All 3 did agree that I needed drain tile around the perimeter to keep
water from getting under slab.
Thanks for any and all input.

I put about 2 cubic yards of gravel (about the size of Brazil nuts)
under my deck inside a frame made from 6x6s. It used to be a mound,
but after 10 years it is almost level. It gets walked on from time to
time but it did the job eliminating a messy, muddy issue.
