I'm overseeing the construction of a road which has required a 2' undercut of the in situ soil. The 2' undercut is being replaced with engineered fill which is a gravelly clay and is being placed in 8" lifts.
The proctor that was performed on this engineered fill indicated that optimum moisture content is ~24%. My crews have been watering the material as they roll it to keep close to this OMC. When we had a nuclear density guage test performed the compaction was adequate at just over 99%, however the moisture content was only 11%. My spec states that the moisture content must be much closer to the OMC.
My question is, if you get the proper compaction in place, how important is it that the OMC is reached?
Thanks!
