Abstract

Proceedings of 2009 GeoHunan International Conference, Challenges and Recent Advances in Pavement Technologies and Transportation Geotechnics, held in Changsha, Hunan, China, August 3-6, 2009. Hosted by Changsha University of Science and Technology, China. Sponsored by Geo-Institute of ASCE, USA; Asphalt Institute, USA; Central South University, China; Chinese Society of Pavement Engineering, Taiwan; Chongqing Jiaotong University, China; Deep Foundation Institute, USA; Federal Highway Administration, USA; Hunan University, China; International Society for Asphalt Pavements, USA; Jiangsu Transportation Research Institute, China; Korean Institute of Construction Technology, Korea; Korean Society of Road Engineers, Korea; Texas Department of Transportation, USA; Texas Transportation Institute, USA; and Transportation Research Board, USA. This Geotechnical Special Publication contains 44 peer-reviewed papers showcasing recent developments and advancements in geotechnical and pavement engineering and offering insights into future directions for geoengineering in the 21st century. Natural soil deposits exhibit a high degree of nonhomogeneity, and their geotechnical properties can change unexpectedly because of varying stress conditions. This makes soil behavior a multidimensional and multifaceted phenomenon. These papers examine the current technological advances in geotechnical engineering, specifically with regard to soil behavior and testing methods. These papers underscore the significance and validity of in situ and laboratory testing in the design of foundations, tunneling, and soil structures. Topics include: soil behavior and laboratory testing; in situ test methods for site characterization, design, and quality control of earth structures and subgrades; pile foundations in subgrade; tunnel engineering.
