Geosynthetics for reinforcement and stabilization

Geosynthetics are widely used for reinforcement and stabilization, particularly in transportation-related applications, including base stabilization, reinforced soil slopes (RSS) and mechanically stabilized earth (MSE) walls.

This issue of Geosynthetics considers many such applications from multiple viewpoints. Sachin Mandavkar and Mehari Weldu look at very tall MSE walls and RSS through several case studies in “Geogrid reinforced soil structures reach new heights.” Benjamin Mahaffay, Jeremy Robinson, Jeffrey Gagnon and Gregory Norwood outline groundbreaking research into geogrids in runways with “Using geosynthetics in flexible airport pavements.” And Jeffery T. Hoilman and Stanley M. Miller present a case study of streambank stabilization with the assistance of elementary school students in “Streambank restoration using engineered bank stabilization.”

In addition, E. Silva and T. D. Stark clarify considerable confusion about various terminology for Elvaloy-based geomembranes in this issue’s Update section. Robert M. Koerner, George R. Koerner and Y. “Grace” Hsuan respond to a wide variety of geosynthetics questions in the column “The GMA Techline Answers All.” The IGS North America’s new president, John McCartney, discusses his vision for the organization in the “IGS-NA News” column. And Jonathan Curry highlights Geosynthetic Materials Association (GMA) happenings in the “GMA News” column.

From geogrids to geomembranes to geotextiles, geosynthetics of many types in innovative applications are featured in this issue.
