HUESKER introduces ecoLine geogrids
July 23rd, 2019
HUESKER launched the world’s first geogrid made from 100% recycled polyethylene terephthalate (PET). With the introduction of the new ecoLine, the company is focusing on even more environmentally friendly solutions that conserve natural resources during production and offer the same quality as their conventional counterparts. The market launch starts with the HaTelit C asphalt reinforcement […]
HUESKER releases a video of bridging sinkholes with Fortrac geogrids
June 14th, 2019
On the LGV (Ligne à Grande Vitesse, or High-Speed Line) Sud Europe Atlantique (SEA) railway line in France, a total of 2583339 square feet (240,000 m²) of Fortrac geogrid provides protection for sections with limestone soils and a high risk of karst and sinkholes. The YouTube video shows the entire laying process in just two […]
Geogrid reinforced soil structures reach new heights
June 1st, 2019
By Sachin Mandavkar and Mehari Weldu FIGURE 1 U.S. Route 460 RSS during construction Reinforced soil structures are geotechnical systems consisting of reinforcing elements and primarily include mechanically stabilized earth (MSE) walls and reinforced soil slopes (RSS) (Figure 1). MSE walls and RSS are constructed by placing alternating layers of reinforcement and compacted soil behind […]
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. […]
Expanding a lakeside road with a reinforced soil slope
April 1st, 2019
Reconstruction of Hennepin County State Aid Highway 112 is a multi-phase project. Phase 1 was completed in fall 2018. Phase 1 included reconstruction and widening of the existing roadway as well as the construction of a bike trail between the road and the lake. The roadway/trail alignment is adjacent to the shoreline of Minnesota’s Long […]
Impact of geogrids on concrete highway pavement performance
April 1st, 2019
The benefits of using geogrids for constructing flexible pavements is well documented. Additionally, the study prepared by White and Vennapusa (2017) discusses the method for field performance verification of the geogrid mechanically stabilized layer. However, this article looks beyond using geogrid mechanically stabilized layers for asphalt pavement design and examines using multiaxial geogrids within concrete […]
The 2019 state of the geosynthetics industry
April 1st, 2019
The U.S. and Canadian geosynthetics market includes geotextiles, geomembranes, geogrids, geosynthetic clay liners, drainage materials, geocells and erosion control materials. In 2018 the U.S. and Canadian geosynthetics market grew in the low single-digit range and is expected to grow somewhat higher in 2019. Consolidation continues in geosynthetics market U.S. geosynthetic manufacturers will likely experience stiff […]
