The fire characteristics of the Municipal noise absorbing screen

Abstract

This article deals with the fire resistance of an innovative noise protection – so called the Municipal noise absorbing screen and its resistance in other dangerous situations with the occurrence of fire. The article briefly describes the characteristics of the noise absorbing screen’s element which is made mostly of the cemented rubber granulate. Due to its geometrical, spatial and material solution the Municipal noise absorbing screen innovatively extends technical opportunities in the field of noise reduction from the rail transport, especially in the urbanized areas. This article also covers the problems of possible causes of fire considering the real installation of the element into the tramway track. The main focus of the article lies in the selection of possible dangerous fire situations. In connection with this, within the experimental part there were carried out reaction to fire tests according to the arranged fire scenarios. There were realized three basic tests in total and their several modifications. In order to that the article describes the effects of the flame on the noise absorbing screen’s element and its damage. Final part is dedicated to the summary of all results from the previous experiments and their comparison. Last but not least there are designed future construction improvements of the element.
