Abstract:

Soil is man's cheapest and most abundant construction material, and compaction is the most widely used method of strengthening soils and making them suitable for construction uses. The technology of compaction, while improving, remains largely in a trial and error state, emphasizing the basic moisture-density relationships discovered by R.R. Proctor. In recent years, the trial-and-error approach has led to the introduction of proprietary trace chemical additives that are said to increase soil densification and ease of compaction, and that improve strength and stability qualities, particularly of fine-grained soils. The report contained herein (Volume I of a two-volume report) includes the principal objectives of Phase I of the total project, i.e., an extensive review of appropriate subject literature and a pilot laboratory moisture-density-strength study of twenty chemicals with eight soils of varying origin and mineralogy. Also included in this report are a theoretical discussion of possible mechanisms of chemical compaction aids, properties of the twenty-six soils used in the total investigation (Phase I and Phase II), and data from supplemental tests designed to improve our understanding of the influences of the chemicals on fine-grained soils.
