Great choice ninetofive!
Even a small movement at the base of a pre-engineered metal building can result in high stresses at the ridgeline of the building.
I'd be very leery of adding moisture into the clays to 'pre-swell' them then building on top of them, Especially in SE Arizona. What...
I've been in Geotech for a few years and have found "The Geoscience Handbook" by the American Geological Institute a helpful book at my fingertips. County Soil Surveys are also helpful.
I'm doing research into soils with LL = 400+, PL = 200+, and free swells on the order of 70% plus. These are obviously extreme results (they caught me by a bit of surprise!) Anyone out there have thoughts, ideas or responses?
What is the application of the project? What is the swell percent and swell stress ?
If it is for a roadway application (I'm presuming this since you mentioned CBR) would replacement of the expansive soil be an option? Or, would soil modification with lime stabilize it sufficiently? Does your...
