what is the void ratio of gravel? | Yahoo Answers· It is the ratio of Void Volume / Total Volume of gravel. It can be calculated by taking the gravel in a known volume (a cubic box for example). After filling the box level with gravel, start adding water gradually using a graduated jar and stop when theChat Online
Crushed stone: rock crushed and graded by screens and then mixed to a blend of stones and fines. It is widely used as a surfacing for roads and driveways, sometimes with tar applied over it. Crushed stone may be made from granite, limestone, dolomite, and other rocks.
crushed stone is a function of the void ratio, since as stated in the previous section, the shear stress-void ratio function is parallel to the consolidation pressure-void ratio function. Therefore, the calcula-tion of the parameters c ' and ~ ' is possible by a least squares fit r r

Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of
Determining What Size Crushed Stone You Need Crushed stone is used for a wide variety of projects, from building roads to providing suitable drainage and from laying a base for pavers to enhancing the look of landscaping projects. There are so many uses for this versatile material, yet many people are unsure of what size they need when it comes to selecting the proper material for their project.
How to Calculate Void Ratio - ProjectEngineerThe 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.

void ratio, this means the entire water column in the well must infiltrate into the soil within 48 hours with an assumed infiltration rate of 0.5 inches per hour. Therefore, maximum Dry Well storage depth at void ratio is: 0.5 inches per hour X 48 hours = 24 inches or 2 feet For a stone filled facility, use a void ratio of 40%.
