  • Aggregate Base Density Data Earth/grading

    Jun 09, 2005· My many years estimating on the con's side give me confidence using a factor of about 150 lbs/cu ft (or about 2.03 tons per cubic yard) -- this is higher than a soil engineer will tell you (that is, a this same aggregate soil compaction at 100% proctor may be about 128-130 pcf dry density; and 138-145 pcf wet density).

I agree with you.

  • The Density of Common Rocks and Minerals

    Jan 23, 2020· The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

  • What is the Density of crushed stone Answers

    2.7T/m3 (+/- 10%). The above answer is for solid rock, generally not crushed stone. Crushed stone of uniform size has a nominal density of 100 pounds per cubic foot (1.6 Metric Tons per cubic Meter).

  • How Much Crushed Stone Do You Need A Sure-Fire Formula

    If your patio is 20 feet long and 10 feet wide, and you need 6 inches of crushed stone for the base, you would plug those numbers into formula, like this: (20'x10'x0.5') / 27 = 3.7 cubic yards When using this equation, make sure all of your measurements are in feet. Since we needed 6 inches of crushed stone, we used 0.5 feet for the height
