Energy in compaction tests

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.

Regards
Agus

RE: Energy in compaction tests

Dear agus,

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

RE: Energy in compaction tests

How do folks get compaction energy from a roller pass in order to compare it to the Proctor-type energies?

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.
