If doing sand replacement test, the density of standard sand need to be verify before each test and also the value of mass of sand in cone should be re-verified. 3.

What does it mean by 95% compaction? - ReadCivil

Mar 14, 2019 · 95% compaction means that the soil on the construction site has been compacted to 95% of the maximum density achieved in the lab. Remember the test in the lab uses a specific compaction effort so it is possible to achieve compaction above 100% in the field. I have seen airstrip plans that specified 105% compaction of a modified Marshal Proctor.
