• Description:
  Compaction of granular base materials at sites with fine grained native soils often causes unwanted material loss due to penetration. In 2007, ODOT began placing geofabrics in the undercut of MSE walls at the soil/ granular material interface to facilitate construction. It is probable that the sliding resistances of the retaining walls are affected by this practice. To address this issue, a systematic investigation of the frictional resistance between soil/geofabric interface and soil/stone interface was conducted by Large Scale Direct Shear (LSDS) test. The research involved Type C granular material, textured geofabrics and fine-grained soils.
