Geosynthetics. Determination of the protection efficiency of a geosynthetic against impact damage Ingestion-build-100998 42:1989 supersedes BS 684-21 Scope This International Standard describes an index test for the determination of the protection efficiency of a geosynthetic on a hard surface, exposed to the impact load of a hemispherical object. The index test measures the change in thickness of a thin lead plate lying between the geosynthetic and a rigid support. It can also be used as a performance test, by using the real rigid surface to protect and the real sequence of geosynthetics. The
