Proceedings of Geo-Frontiers 2011, held in Dallas, Texas, March 13-16, 2011. Sponsored by Geo-Institute of ASCE; Industrial Fabrics Association International; North American Geosynthetics Society; Geosynthetics Materials Association. This collection contains 496 peer-reviewed papers that describe advances in research and the practical application of geotechnologies, especially including geosynthetics. Papers from a memorial session to honor Bernard Myles for his contributions to the geosynthetics industry are also collected in this volume. Topics include: foundations and ground improvement; geoenvironmental engineering; geohazards (earthquakes, landslides, erosion); geosynthetics; geotechnical testing and site characterization; slopes, embankments, and earth-retaining structures; soil rock mechanics and modeling; and transportation materials and pavements. These papers will be of interest to geotechnical researchers and practicing engineers, especially those working with geosynthetic materials
