RES2020-10: Guidelines for the Use of Expanded- Polystyrene (EPS) Block Geofoam as Lightweight Backfill Behind Retaining Walls

项目名称：	RES2020-10: Guidelines for the Use of Expanded- Polystyrene (EPS) Block Geofoam as Lightweight Backfill Behind Retaining Walls
摘要：	Geofoam has successfully been used in numerous projects predominantly in Europe, Japan, and the U.S. as lightweight fill to support roadway embankments. However, geofoam has not been used extensively in Tennessee because the Tennessee Department of Transportation (TDOT) does not currently have a geofoam design guideline and material special provision for the use of geofoam. Although studies have been performed by other state DOTs on use of geofoam as lightweight fill in embankments over soft ground and two National Cooperative Highway Research Program studies have been completed that focused on use of geofoam as lightweight fill in embankments over soft ground and in stabilization of slopes, none of these studies have focused on the use of geofoam as lightweight backfill material behind retaining walls or bridge abutments. This research addresses this need of developing a design guideline for the use of geofoam as lightweight backfill material behind retaining walls and abutments over soft ground.
