This volume includes a collection of technical papers on an important topic in geotechnical engineering; the behavior and treatment of expansive soils. The research studies include investigations into novel stabilization techniques for expansive soils using different admixtures or mechanical consolidation techniques, as well as new experimental approaches to evaluate the behavior of expansive soils. They also include an evaluation of wetting boundary conditions on the volume change of expansive soils, as well as the role of hydrologic boundary conditions in arid climates. The volume is based on the best contributions to the 2nd GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2018 The official international congress of the Soil-Structure Interaction Group in Egypt (SSIGE).

Highlights the recent advances in admixture effects on the behavior of expansive soils Includes investigations into novel stabilization techniques for expansive soils using different admixtures or mechanical consolidation techniques Discusses the use of image analysis to evaluate expansive soil volume change
