Energy in compaction tests
Energy in compaction tests
(OP)
Dear all,
Does anybody know how to calculate energy per unit volume of soil induced in standard proctor compaction test. I know the amount of the energy but could not find out how to get that number. I need this information as I am compacting my soils using different number of blows, number of layers and different hammers. I would be glad if anybody can help me. Thanks a lot.

RE: Energy in compaction tests
E=n*h*P/V (kgm/m3) (1 j=0.1 kgm)
here
n=# of blows
h=Falling height
P=hammer weight
V=volume of sample
take care
bye

In practice you measure the optimum compaction as determined by a proctor test versus the actual compaction as measured in the field.
Usually there is a specification or code requirement for the actual dry density to be a percentage of the proctor.
