Mixture Design Optimization of Low-Noise Pavements

Abstract: This paper proposes a tool to optimize the mix design of low-noise pavements. An experimental model was developed to predict the rolling noise of a reference car tire as a function of the composition and volumetric characteristics of mixes obtained from in-service pavements. The model enables an analyst to identify which composition parameters need to be altered to improve the acoustic performance of a low-noise pavement. To define the experimental model, several types of asphalt surface layers composed of hot… Show more

“…An extended literature review of several researcher outcomes [17][18][19][20][21][22] allowed for the determination of correlations between the air-void content and noise level (see Figure 1) and mean profile depth (see Figure 2). Based on other researcher's measurements, it can be seen that a low-noise-level (below 100 dB) asphalt mixture can contain 2.3%-28.5% air-voids; however, all asphalt layers with an air-void content of more than 8% assures less than 98.5 dB noise (see Figure 1).…”

“…A multi-year acoustical monitoring was carried out by means of SPB and CPX methods and results are shown in this paper, and the availability of the experimental road surfaces are a good opportunity to perform further side researches on collected data (for example, see [7][8][9][10][11][12]), including analysis on vibrations whose elaborations are still ongoing.…”

“…All installations are about 200 m long and placed on extra-urban roads not in densely urbanized areas. For more details on composition, volumetric characteristics, aggregate grading and fractal dimensions of the mixtures see [11]. It is necessary to underline that the experimental surfaces have been laid in contexts which present different local surrounding conditions (lane width, roadside ground, guard-rail, slope, exposure to sun, traffic density and typology etc.).…”

“…Airborne noise is related to the compression of the air trapped within the tread of the rolling tire [4]. Studies regarding optimal road texture and mixture design for noise abatement are widely available [5][6][7].…”
