how many cubic yards would result from 20 tons of gravel

Postby Dip Stick » Fri Dec 15, 2006 5:08 am

For example: A standard tandem axel dump truck can carry approximately 16 cubic yards or approximately 22 tons tons of stone or gravel. Therefore, you can safely assume 16 +/- cubic yards.

From Clayton Masonry Centers (further info)
One Ton of stone/gravel will cover:
220 SqFt at 1 inch deep
115 SqFt at 2 inch deep
75 SqFt at 3 inch deep
60 SqFt at 4 inch deep

Hope the info helps - Dip

So then if I have 180yards of stone, how many tons do I have?

Sized from 1/4" to 2", an approximate weight per loose cubic yard of gravel (as loaded in a dump truck) is 3400 pounds wet, 2850 pounds dry, anywhere in between and can be somewhat outside those weight boundaries.

That's a long answer for an approximation but weight to volume factors differ because of different rock densities, moisture content, velocities, etc.. An individual gravel pit will have a more accurate volume to weight factor for the product they produce but even that will change slightly from run to run.

Why add water? Dust control is the main reason. Few pits have "dry" gravel. Even expensive, oven treated material has some moisture content. The higher the moisture content, the higher the weight.

If you use a weight of 3125 pounds per loose cubic yard of gravel, you'll be close. That gives you a cubic yard to ton weight factor of 1.5625.

1.5625 tons/yd^3 * 180 loose cubic yards of gravel will weigh approximately 281 tons, plus or minus.

16*4*2 = 128 ft^3,
128 ft^3 / 27 ft^3 = 4.74 yd^3
4.74 yd^3 * 1.5625 tons/yd^3 = 7.4 tons approximately.
