Papers on compaction practices

This publication comprises the following two papers: compaction practices and equipment, by ladner, pa; and compaction and moisture control, by cocks, gc. It has been compiled to enable a wide distribution of these technical papers outlining the principles of compaction, the effective use of plant and also the importance of moisture in the compaction process. For each combination of soil and equipment type there is an optimum moisture content at which compaction can be most efficiently achieved. It should be recognised that control of soil moisture content can often be a more important factor in achieving the specified density than the selection of compaction equipment.
