Selecting reinforced fill soil for MSE retaining walls
June 1st, 2006
A full-scale field test is currently being conducted to establish properties for “high fines” reinforced soils and associated design controls that give acceptable MSE wall performance. By Richard P. Stulgis Mechanically Stabilized Earth (MSE) retaining walls on public sector transportation projects are generally conservatively designed with “low fines” reinforced soils. Private MSE walls are less […]
