Stabilization and reinforcement of wind farm access roads with geosynthetics
October 1st, 2019
This project is the construction of the first commercial-scale wind farm in North Carolina. It was for a renewable power generation facility providing clean energy. Constructing the wind farm required subgrade stabilization and reinforcement for more than 60 miles (97 km) of access roads that needed to be built in order to erect 104 turbines […]
Geosynthetics for reinforcement and stabilization
June 1st, 2019
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 […]
Using geosynthetics in flexible airport pavements
June 1st, 2019
By Benjamin Mahaffay, Jeremy Robinson, Jeffrey Gagnon and Gregory Norwood FIGURE 1 Post-test excavated cross section In recent years, there has been an increasing interest to improve pavement structures through mechanical stabilization by incorporating geosynthetic products within the structure. The Geosynthetic Materials Association (GMA) has identified eight categories of commercially available geosynthetics: geotextiles, geogrids, geonets, […]
Los Angeles Museum of the Holocaust foundation improvement
June 1st, 2019
The Los Angeles Museum of the Holocaust. Photograph courtesy Belzberg Architects The Los Angeles Museum of the Holocaust needed a foundation improvement solution for its new and innovative earth-sheltered facility. Jon Irvine, the project engineer, of Irvine Geotechnical Inc., suggested using a mechanically stabilized earth (MSE) mattress as an affordable alternative to overexcavation and replacement. […]
