An Introduction to Stabilization of Subgrade Soils J. Paul Guyer

This publication will introduce you to methods, materials and equipment for stabilization of subgrade soils. The depth of stabilization generally must be sufficient to absorb most of the foundation pressure bulb. The relative benefits of vibrocompaction, vibrodisplacement compaction, and precompression are discussed. Soft, cohesive soils treated in place are generally suitable only for low-intensity loadings. Soil stabilization of wet, soft soils may be accomplished by addition of lime; grout to control water flow into excavations to reduce lateral support requirements or to reduce liquefaction or settlement caused by adjacent pile driving; seepage control by electroosmosis; and temporary stabilization by freezing.
