Air Drying of Soils

[mmdbos]

I am curious as to whether anyone has seen any documentation or testing which indicates what temperature soil can be air-dried prior to placing and recompacting. In my experience in New England, it can only be done in Summer months (> 60 deg. F). I know there are lots of other factors (i.e., rainfall, humidity, % of fines, etc.), but I wonder if there is any documentation of what people have seen.

Unfrozen with low humidity. It just slows down the cooler and more humid it is.

It also depends on how much the contractor wants to work the material, as well. Keep turning it over, and it will help it dry.
