Frequently Asked Questions
What is the Optimum Moisture Content (OMC)?
The Optimum Moisture Content is the water content at which soil achieves its maximum dry density for a given compaction effort. At this moisture level, water lubricates soil particles allowing them to pack more tightly, while not so much water fills the voids and prevents densification. The OMC is determined from the peak of the compaction curve, which plots dry density against water content. Typical OMC values range from 8-15% for granular soils and 15-30% for fine-grained soils.
Why is 95% compaction typically specified?
A 95% relative compaction requirement means the field dry density must be at least 95% of the maximum dry density from the laboratory Proctor test. This standard is widely used in construction specifications because it provides adequate density for structural support while being achievable with standard field compaction equipment. For critical structures like dams or heavy buildings, 98% or even 100% compaction may be required, while for less critical fills 90% may suffice.
