Design and validation of a new asphalt mixture to reduce road traffic noise pollution in urban areas
The aim of this paper is to design a novel asphalt mixture capable of reducing tyre/pavement interaction noise for urban roads at speeds around 50 km/h. To this end, various mechanical and functional tests were carried out both in the laboratory and on a real road in the city of Florence. The asphal...

| Resumo: | The aim of this paper is to design a novel asphalt mixture capable of reducing tyre/pavement interaction noise for urban roads at speeds around 50 km/h. To this end, various mechanical and functional tests were carried out both in the laboratory and on a real road in the city of Florence. The asphalt mixture developed improves the noise reduction properties without compromising its mechanical performance or neglecting its rolling and skid resistance. To this end, various mechanical tests were carried out in the laboratory, including water sensitivity or wheel tracking tests, as well as functional tests relating to texture, flow resistance and sound absorption. Fullscale measurements were carried out using the CPX method. The result of the study was a novel asphalt mixture that reduced noise by 3 dB compared to a conventional road |
