Summary:
This article aims to show the steps followed in the solution of a noise pollution problem in an urban area. The actions which have been carried out not only aim the reduction of the noise level but also reduce the number of people affected. The methodology followed starts with the initial study of the strategic noise maps of the affected area with the acoustic problem (in this case, the area of the autonomous road A-376 at the height of Montequinto has been analyzed). It is important to show that the models currently used in the preparation of the strategic maps assume very basic calculation hypotheses, which do not allow us to faithfully represent the real situation, so it is very complex to make decisions in order to establish action plans only from them. In order to solve this problem and after analyzing the maps of the area, an experimental diagnosis of the area was made. The main objective of this second step was to bear out if the road noise was one of the dominant sources in the studied area.\nOnce verified that the origin of the problem was the road noise, we proceeded to the design of the bituminous mixtures incorporating special additives to increase the sound reduction. An experimental design was made with more than 20 different formulas where different parameters that influence the noise produced by the rolling of the vehicles were evaluated as output variables. Subsequently, the paving and subsequent acoustic evaluation of the levels and people affected in the area was carried out.\nThis example has been developed within the LIFE-SOUNDLESS demonstration project co-financed by the European Union and whose main objective is the mitigation of noise pollution in urban agglomerations using sound-reducing bituminous mixtures that generate less sound emission levels.
