Some Effects of Rubberized Asphalt on Decreasing the Phonic Pollution

Abstract:

An important contribution to the noise generated by the road transportation means in the environment has the noise produced by the tire-road contact. This paper is concerned with the investigation of the noise produced by the contact between the tire and the rolling surface covered by rubberized asphalt. Initial test performed in the past were performed again in identical conditions in order to assess the durability and absorbent properties of the rubberized asphalt over time in the climate specific to Timisoara. It was found that the rubberized asphalt has not changed its acoustical properties over time, since practically the same values were obtained for the equivalent noise level as well as for the spectral distribution of the noise, which confirm the efficiency of rubberized asphalt to decreasing phonic pollution in urban areas.
