1. How Do Geopier Rammed Aggregate Piers work in slope stability applications?
For applications where increased shear resistance is required — for example, global stability of MSE walls or embankments and stabilization of landslides — RAP elements can increase the composite shear resistance. With measured friction angles of the constructed element ranging between 48 and 52 degrees, RAP elements provide significant increases in shear resistance and afford increases in the factors of safety for stability. For more information, please see Technical Bulletin No. 5 on RAP Systems, Shear Reinforcement for Global Stability.
