shrink/swell potential of shales

[civilmg]

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?

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.
