Steady State Overtop Testing – Intentional Damage

This test was designed to evaluate the performance of the HydroTurf® Revetment System in a damaged state. A pickaxe was intentionally driven through the HydroTurf™ System and into the underlying sandy-loam subgrade. Testing was performed at the 3-ft and 5-ft overtop depths.

No instability or discernible erosion was observed. After removal of the HydroTurf System, the subgrade was inspected. There was no erosion and the initial hole closed. Also, the subgrade along the entire embankment showed no signs of erosion.
