This book is based on the study that was carried out to get information about the soil stabilization and modern developments used in bitumen usage. The basic aim was to provide a comprehensive literature on different techniques of soil stabilization and modern advancements in Bitumen usage. In this view detailed methods for soil stabilization are discussed .Detailed studies on Bitumen usage and their application have also been carried out and different laboratory and field tests that are required to ensure the strength and other geotechnical properties of soils using bitumen have been discussed. Also the usage related to the properties of bitumen like in buildings, hydraulic structures and pavement construction have been studied .Information regarding the uses of soil stabilization in Pakistan have also been carried out. Soil stabilization techniques are discussed in detail, which includes simple stabilization methods to newly developed concept i.e. by using admixtures. At the end, book is concluded with some conclusions derived in the light of the study and some recommendations have also been given.
