The intent of this work is to present an international overview of advances in geotechnical engineering referring to design and construction of road pavements and rail tracks for high-speed trains. It seeks to influence the international pavement and railway engineering community to move away from merely empirical procedures towards a sophisticated approach based primarily on proven theoretical concepts.;The volume covers compaction technology in construction, properties of geomaterials relevant for design and construction, effects of grain crushing, freezing-thawing problems, and embankments for highways and high-speed trains (in-situ tests, modelling, design, monitoring and specifications). It contains 16 contributions including two special lectures: one about high embankments instead of bridges and bridge foundations in embankments, and a second one about impacts on geotechnical engineering from findings of laboratory stress-strain tests on geomaterials. - from Amzon
