When ordering road gravel for paver & wall base, what is the weight per cu. yd? I need 8.6 yards but I don't know what weight that is.

On the other hand, what coverage does 1 ton of road gravel give you?

Thanks.

I've always found a cubic yard to weigh approx. 1.2 tons. It depends, obviously on the density, and size of the material.

We usually figure yd3x1.5, plus x 1.5 for compaction

yd3 = cubic yard
x 1.5 = 1.5 tons per cubic yard
1.5 for compaction = the number of yards you come up with for the job multiplied by 1.5 to get the total amount you will need after compaction.

DUH!

Does about 10 ton seem right for 350sf of pavers & wall base? I'm assuming 4" depth

I'd figure more then that. Up in toronto i'd want atleast 6-8 inches of base material. I normally do a minimum of 6 here in nj.

I also go about 6-8" for walk/patio.

You should really learn to do the math on your own.

350ft2 * .5 (6" base) = 175/27(1yd3)= 6.48yd3 * 1.5 = 9.72 *1.5 (for compaction) = 14.58 ton

be sure you're adding in the required sq ftg for your 4-6" shoulder around the flatwork.
