A new approach to the topic of numerical description of void characteristics of noncohesive soils and similar granular materials is presented. Based upon a simple stochastic model of the void structure and void sizes, theoretical equations are derived by means of which the void ratio of a soil can be calculated from its grain‐size distribution.

Stormwater detention systems often include a large portion of the storage volume within the voids of the backfill material. Depending on the underground structure design and size, allocated storage within the stone voids can vary between 25-60% of the overall storage for the project. The generally accepted number has been 40% stone void space.

⇒Volume of void cannot be zero for soil as it is at least two phase system,however it can be zero for rock. e = Vv / Vs . Add 1 both sides. e+1 = Vv/Vs +1. e+1 = (Vv+Vs)/Vs. We know that Vv+Vs= V (total volume of soil). ... hence void ratio & water content of fine grained soil is more than coarse grained soil . ( For compare make sure volume ...

It depends upon the specific gravity of the stone as well as the gradation. I use a dry rodded unit weight of 1630 kg/m3 and a specific gravity of 2.68 for the gravels in my location. That would equate to a void ratio of about 0.62 ignoring the pores on …
