Author Description

Residual soils generally are derived, in place, as a result of long term weathering processes of the underlying bedrock formations. Between the surface soils and unweathered bedrock are varying stages of decomposed rock. The nature of this subsurface profile is highly variable, both horizontally and vertically. The papers discuss state-of-the-art approaches to the characterization of residual soils by use of field tests (STP, Pressuremeter, and Dilatometer) and laboratory testing and present case studies.
