Compactability
Compactability
(OP)
Hello,
say, I have fine material of which strength is very stiff clay to extremely weak rock (S5-R0). I would like to build a soil structure, by compacting it. Is any method available to figure out how easy/difficult the compaction would be ? Do you think I can say something from Standard/Modified compaction test ?
Thank you in advance !!

I am talking about a site in tropical region. I see thin overburden of laterite and thick completely to highly weathered bedrock underneath. I would like to use the weathered part to build embankment. Thus I have to know how compaction would be and how much material we can borrow. It depends on our specs and compactor we gonna utilize after all, if there is no popular way. I better talk to manufactuerer of compactors ??
Cheers,

Of course, if you can't seem to get your desired compaction with an 825, it's probably time to check your data.

Not real worried about the mudstone at my site doing much more over time. They got it pretty well broken down with the 825 (low measured K in falling-head test), and it was silty-clayey sedimentary rock so I don't think it will undergo much change in minerology in human time. Once it's compacted in the core, it probably wouldn't matter anyway. Or was your question about long-term effects referring to Tatsu's laterites? (I know very little about them.)
RE: Compactability
My comments about continual breakdown was a general one that one should think about. If you have considered it and made a conclusion, then fine!

Test fill has to be done prior to construction for sure. It is at pre feasibility stage at this moment. I guess best I can do now is to make sure the material can be densified well by proctor test, and get basic properties such as shear strength, k, wopt.. those kind of things.
