Estimating DGA

[coatsandrew]

I was asked by a contractor how much area would a ton of DGA cover at a 4" depth? I don't have any experience with DGA, but to me it's more of a mathematical question regarding densities and volumes. It is that simple, or are there formulas for these characteristics associated with DGA?

What is DGA??

 

[coatsandrew]

Dense Grade Aggregate.

You have to look at the gradation of the aggregate and the volume of voids which makes it a simple volume calc.

Area = Volume/depth
Volume=weight/density
Density is approximately 145 lbs/cf (dry weight, compacted)


A=2000 lb / (0.33' x 145 pcf) = 40 SF
