Abstract:
The core-cutter method can disturb a sensitive municipal solid waste (MSW) sample when
measuring dry density of the soil. A mechanism has been developed to reduce this disturbance significantly,
thus trying to obtain an accurate value for the dry density. The “resistance to the penetration” parameter of the
soil was used as the theoretical background to develop graphical solution. An instrument was developed to
measure penetration per blow value and it was calibrated with actual dry densities using Proctor compaction
test. This mechanism was used to measure the compaction effect of heavy dynamic compaction, used in a predetermined
grid pattern on a prepared MSW sample.
