This report describes the development of a standalone engineering soil database that may be used with the design, evaluation, maintenance, and repair of airfields around the world. The soil database was developed using data from different sources. The soil data are divided into three tiers Tier 1, Tier 2, and Tier 3. Tier 1 Data are soil data that have been measured, collected, and reported by verified U.S. Army Corps of Engineers USACE reports based on measurements and testing including the Unified Soil Classification System USCS. Tier 2 includes data that reports USCS classification, but the data have been collected from non-verified sources such as other non-USACE reports, web sites, and published articles. Tier 3 Data includes data with alternative soil classification systems such as agricultural and geological soil classifications and soil parameters. Tier 3 Data were converted into equivalent USCS classification system. The standalone database described in this report is being converted to a web-based tool for technology transfer. At the time of publication, the database includes Tier 1 Data for 53 countries, Tier 2 data for 16 countries, and Tier 3 Data for 31 countries. The database will be updated periodically as additional data sources are identified and verified.
