Hi all,
I may be involved in a project of a pretty large industrial building. An issue which I'm not familiar with is going to be design of base/subbase and improvement of subgrade, which is several meters of clayey soil which shrinks and expands with variations in moisture. Basic practical points: Replace or not replace with engineered subgrade, thickness of replacement, replace or stabilize chemically, tests to carry out on natural subgrade, how to avoid shrinkage and expansion issues. Any reference practical material and codes on such subjects? I'm asking this before spending hours in searching the whole eng-tips forum!
