Disposal of waste in municipal solid waste landfills is the only way of waste
disposal in Serbia, with daily compaction and covering with soil material. Due
to less space for the construction of new landfills, it is necessary to use their
maximum capacity. Well-compacted municipal solid waste takes up less volume
and enables safer storage, so it is useful to previously determine the compaction
parameters in the laboratory: maximum dry unit weight (γdmax) and optimal
water content (wopt). In the practice so far, the standard method has been used
to obtain these parameters (Proctor compaction test) which is common in soil
mechanics. However, although this methodology has been adopted, different
treatments of municipal solid waste at the landfill (including pre-treatment)
indicate the need to change this classical approach. Therefore, during the research, various innovative solutions are introduced, such as the change of the
classic flat Proctor hammer, by adding spikes, whose function, in addition to
compaction, is partial destruction and shredding of municipal waste. In this
way, the operation of compactors (hedgehogs) in the field is simulated. The
paper presents the behaviour of four artificially prepared samples of municipal solid waste of different composition. The samples were tested in the standard
Proctor apparatus at the same compaction energy, using different hammers, a standard flat hammer, and an innovative hammer with spikes. After that,
the geotechnical effects of compaction depending on the applied approach were analyzed.
