The main aim of this book is provide some general information about the different types of soil stabilization methods. Readers can use references for more information about those methods. Also in this book tried to describe the new method of using waste material in soil stabilization such as glass as an inexpensive material by laboratory tests. I do hope that information in this book will help readers develop their knowledge and career in the discipline of geotechnical engineering. Certainly the contents of this book miss many important issues. Ehsan Haghshenas March, 2013
