Polished Cone Drop Test Apparatus, Color : Silver

Method to determine the resistance of geosynthetics to penetration by steel cone dropped from a fixed height, as a simulation of dropping sharp stones on their surface. Generally applicable to all geosynthetics. However, the test principle may not be applicable to some types of products. The specimen is clamped between two steel rings. A steel cone (45° tip angle, 1000 g) is dropped from a height of 500 mm onto the centre of the specimen. The degree of penetration is measured by insertion of a graduated cone into the hole.
