IMPACT WEAR EFFECT ON SOUND ABSORBING PANELS

Elena Adelina CHIRIAC, Carmen BUJOREANU, Marcelin BENCHEA

Abstract


Noise pollution has been increasing in the last years which leads to significant interest in the technical solutions used to reduce it. This paper aims to realize the comparative analysis between two prototypes of sound-absorbing panels (one made from a raw material and the other one having a coating of epoxy resin) used in road traffic, subjected to an impact wear. Taking into account that the proposed sound-absorbing panels will be placed along roadways, we took into consideration the possibility that vehicles traveling on the road may throw stones onto the surface of the panels. Regarding the conducted experiment, its purpose was to demonstrate that the layer poured over the raw material provides it greater resistance to impact wear.
