Special Issues: Characterization and Engineering Properties of Natural Soils used for geotesting

In 1995, a geotechnical experimentation site was established in rural Lee County, Alabama near the area often referred to as Spring Villa. The Auburn University National Geotechnical Experimentation Site (AUNGES) site is situated near the southern terminus of the Appalachian Piedmont Physiographic province. The site consists of two sub sites, one that is a thick profile of residual soil and the other is an outcrop of fractured weathered quartzite. Extensive site investigation has been conducted at the site by many agencies and researchers using a wide array of in-situ soil tests. Foundations, excavations, and retaining structures have been constructed and load tested at the AUNGES. This paper summarizes all the work conducted at the site since its inception. Maps that detail the location of all in-situ tests and structures tested were generated. Representative profiles are included that relate early site investigation, between 1995 and 2005, and contemporary work done after 2010 are generated based on the results of piezocone, dilatometer, standard penetration, and shear wave velocity tests.
