How to Calculate Void Ratio - ProjectEngineer

Dec 16, 2013 · The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids.. Where: e = Void Ratio V v = Volume of voids (m 3 or ft 3) V s = Volume of solids (m 3 or ft 3) V g = Volume of air (m 3 or ft 3) V w = Volume of water (m 3 or ft 3) The void ratio is thus a ratio which can be greater than 1. It can also be expressed as a fraction.

How much volume is lost after compacting 3/4" crushed stone?

With a more properly graded 3/4" washed stone (such as a good filter stone ranging between the 3/8" and 1" diameter), you will have a loose drop of more like 75%, but you will also actually be able to get closer to 100% without talking about your subgrade. If the subgrade is sandy, it will not invade such a well graded gravel as much.
