Book excerpt: Compaction curves from 16 coarse- and 9 fine-grained soils, which cover all soil types classified by the Unified Soil Classification System are analyzed to develop the Modified Ohio's curves. For all soils, the relationships between water content and degree of saturation on both the dry and the wet sides of optimum are represented by power functions. Their compaction curves under standard Proctor energy follow the Ohio's curves. Optimum degree of saturation, ODS, of coarse-grained soils is lower than that of fine-grained soils. However, for a given soil, the ODS is practically the same for different compaction energies, E. Even though compaction characteristics (optimum water content, OWC, and maximum dry unit weight, ?d max) are different for different soils, their relationship between normalized OWC/OWCst and E is practically the same, where OWCst is the OWC at standard Proctor energy. Based on this finding, the Modified Ohio's curves are introduced under compaction energy levels of the half standard, half modified, and modified Proctor energies. The verification of the Modified Ohio's curve is also illustrated in this paper. These curves are useful in rapid estimation of laboratory compaction curves from a single set data of dry unit weight and water content.

Available in PDF, EPUB and Kindle. Book excerpt: A complete compaction curve for fine-grained soil and its characteristics are discussed. The formulation of the relationship to model the curve is introduced. The equation is versatile in its ability to quantify the shape, size and position of compaction curves. It is capable of describing the compaction curve from the dry to very wet condition and can be used to predict a family of compaction curves for a given soil for different input of compaction energies. All parameters in the equation have specific physical definitions. Simple procedures to obtain all parameters directly from a standard compaction curve are developed and described in detail. The examples show that the proposed equation is good at representing the soil compaction curve and demonstrates excellent agreement between laboratory test data and the predicted curves. The family of curves predicted by the equation would improve the practice of the one-point method in the field.

Book excerpt: Curves of dry density versus moisture content, as yielded by the standard ASTM compaction tests, usually show a single maximum, but some soils exhibit compaction curves with irregular shapes. This study examines some of the influences of soil preparation on these irregular compaction curves. When a surface tension reducing agent, such as aerosol-AY, is added to the water in soil specimen preparation, the shape of the irregular compaction curve will be altered. This effect is regarded as a verification of the effects of negative pore water pressure on the irregular compaction curve. In repeated compaction tests, it is economical and convenient to reuse the soil specimens. The results of liquid and plastic limit tests reveal approximately the same values in new and reused specimens. However, the reused soil specimens reveal a predominantly higher density in the zone of lower water content in an irregular compaction curve.
