David Arellano, University of Memphis, presiding
Sponsored by Standing Committee on Geosynthetics (Changed to AKG80 on 4/15/2020); and Standing Committee on Transportation Earthworks (Changed AKG50 on 4/15/2020)

The objective of this workshop is to provide participants with an overview of expanded polystyrene-block geofoam applications such as embankments over soft ground, slope stabilization, bridge abutments and approaches, temporary and permanent bridge support, retaining wall systems, culverts and utilities, rail systems, and airport applications. The workshop will cover key material properties and general considerations, design overview, construction aspects, performance monitoring, and cost.
