shrink/swell potential of shales

shrink/swell potential of shales

(OP)
Does anyone have any literature, of knowledge of, the shrink/swell potential of shales?  

We are looking to use New Albany shale as a structural fill on a particular site.  Is there a criteria for determining if this material has excessive sulfide content?

RE: shrink/swell potential of shales

A engineering type lab may be able to determine sulfides in a specific lab test.  Shale can be used as a fill layer, but, should be choked with a sandy layer. It is more preferable to mix the shale with sand, to get a good fill.  Your engineer assigned to the sight could approve the use and specify how to use it.
