Hi, how can I relate a specific grade of compaction to its compressibility? For example, if soils are compacted to 80% modified proctor, how can I relate it for settlement calculations? I guess I should start looking at the void ratio for the 80% compaction. Soils are silts with high water contents. We are stabilizing them with cement for roads subgrades, but looking at the Proctor results, soils may only be compacted to ~80%. I was worried about settlement issues due to low compaction degree. I think that other issue is that the subbase/base may not be able to be compacted properly if the subgrade gets compacted only to 80%.
