This paper provides a review of soil compaction principles and practice. The nonlinear relation of compaction energy to resulting density is shown. The need to consider the effect of change in moisture from the as-compacted state is pointed out. Factors that influence the reference test for specifying compaction are discussed to show the uncertainty in the resulting maximum dry density and optimum moisture content. Factors that influence field compaction are also described, and the possibility of a large variation in compaction results with field conditions is demonstrated. The need for more awareness of the effects of methods of preparation and uniformity of procedures is indicated. Limitations of density as a method of specifying compaction are pointed out. The type and magnitude of compaction measurement errors are defined and implications for compaction control are discussed. Finally, because knowledge of compactor performance in combination with observation of field procedures is a meaningful basis on which to judge compaction, some basic principles of compactor performance evaluation are described.
