In case the compaction test results indicate values exceeding 100%, it only means that the in-situ compaction is more than that being carried out in laboratories which is treated as the basic criterion for satisfactory degree of soil compaction. Therefore, the soil results are acceptable in case compaction test results are over 100%.

Proctor compaction test - Wikipedia

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.The test is named in honor of Ralph R. Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil compaction.

Fundamentals of Soil Compaction

SOIL COMPACTION Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. 3.1 Purpose of Compaction • The principal reason for compacting soil is to reduce subsequent settlement under working loads. • Compaction increases the shear strength of the soil.

Do soil compaction test results over 100% mean over ...

Soils can experience over-compaction if the compactor makes too many passes over it. In fact, relative soil compaction test results over 100% do not necessarily mean over-compaction because the relative compaction is based on the maximum dry density of the soil obtained by the Proctor test and this does not necessarily refer to absolute maximum dry density.
