Mar 18, 2019 This gravel packs more tightly and wont drain as well. If you order just plain ol gravel, theres no real telling what you will get but it will probably have some crushed component and some rounded. For the best drainage, specify exactly what you want (rounded stones), and that is river stone. 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.

The crushed stone has a void ratio of approximately 33%, so the storage capacity under the panel drains is approximately 11,880 cf 200 wide x 360 long x 6 depth stone x 0.33 . This storage capacity allows for the majority of stormwater to infiltrate into the underlying soils . Void ratio of brick aggregate was much higher than that of stone aggregate. ASTM C127 standard procedure was used to measure the bulk specific gravity and absorption of aggregates.
