Unsaturated soil mechanics is now increasingly recognized as an integral part of mainstream soil mechanics, and the importance and relevance of this area for the broad field of geotechnical engineering no longer needs to be emphasized.
This book contains contributions which describe field and laboratory studies in unsaturated soils and expansive soils and includes papers from the 4th Asia Pacific Conference on Unsaturated Soils, held in Newcastle, NSW, Australia, 23-25 November 2009.
