one interesting observation from the tables you have referenced is the significant reduction in cohesion on saturation. I presume these relationships were generated by sampling the compacted lift and lab testing in the compacted state and also after soaking of a lift sample in the laboratory...
Many engineers compact a sample of fill in the laboratory using one of the standard tests, extrude the sample from the mould and then subject it to a second laboratory test to determine a relevant engineering property such as strength. this approach needs to recognize that the compaction...
No it is not correct to say that 95% compaction corresponds to 5% air content. It depends on the moisture content at which the 95% relative compaction is achieved. Typically for a medium plasticity clay compacted at the standard Proctor effort such that the lab test's optimum point is...
Many engineers consider that for cohesive fills if they achieve a certain relative compaction based on one of the standard laboratory compaction tests they will achieve a certain minimum shear strength and hence bearing capacity or slip resistance. This assessment of shear strength is largely...
