Experimental Investigation of Transparent Glazed Noise Reducing Traffic Barrier against Impact of Flying Stones

Abstract:

Number of experimental tests was carried out to simulate a flying stone at road noise barriers under laboratory conditions in the Klokner Institute laboratory. Prefabricated modules made in the Czech Republic were used for these experiments. It was designed testing system consisting of a toughened steel pin, the guiding device and the supporting scaffolding. This system allows to simulate the impact of the steel hammer with kinetic energy of 30 Nm in accordance with the requirements of the standard ČSN EN 1974-1 [.
