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 […]

GWFV walls and slopes
October 1st, 2017
New patented technology is available to construct geosynthetic wrap-face vegetated (GWFV) retaining walls and reinforced soil slopes using a pyramidal-woven, high-performance turf reinforcement mat (HPTRM) in conjunction with fiber-composite internal braces. This wrap-face system eliminates the need for temporary external bracing (formwork) or for facing elements comprised of metallic wire-frame units, which traditionally have served […]
