You will only get dry densities close to the zero air void line if you can pack all the voids, however if as described you have a fine sand, there may be insufficient fines to achieve this. If field compaction percentages are too low or seem too high, there are some things to consider: The compaction energy from heavy equipment dissipates as the depth of the loose soil layers increases. Remember that the values of water content, wet . Successful IT departments are defined not only by the technology they deploy and manage, but by the skills and capabilities of their people.
