Estimating gallons of H20 per cubic yard
Estimating gallons of H20 per cubic yard
(OP)
Is there a table or formula available to better estimate how many gallons of water it may take to raise the moisture content of existing soils during compaction?

Say optimim moisture content is 12% and soils are at 8%, and maximum dry unit weight is 110 lbs/cufic foot. You need to increase moisture by (12%-8%)x110 or 4.4 lbs/cubic foot. Since there are about 8.34 lbs/gallon, you need 4.4/8.34=0.53 gallons/cf. This is per cubic foot at 100% compaction; you would need to factor lower by in place density divided by max dry density.

I guess what I am saying is that adding the water is not a precise science, therefore you may be expending a whole lot of time in determining this calculation when in reality, it will be about as useful to the contractor as knowing the actual number of 3/4" rock in a 4-20 sample. The importance is the application and satisfaction of the specification, or the end result. I suppose it makes for an interesting exercise in theory.
