Environmental noise is one of the problems modern societies face today. Traffic noise,\nespecially the noise produced from tire/pavement interaction, plays a main role in environmental\nnoise. Pavement rehabilitation with new bituminous mixtures is a good option for combatting\nnoise pollution in urban areas. This paper studies the functional performance of two bituminous\nmixtures of stone mastic asphalt (SMA), fabricated with the same polymer modified binder, but\nwith different maximum aggregate size (MAS) (SMA11 and SMA16). The acoustic absorption, the\ndynamic stiffness, the surface texture and the tire/pavement noise were assessed. The bituminous\nmixture type SMA16 has higher texture levels at nearly every depicted wavelength of the texture\nspectra. This characteristic may lead to its higher average tire/pavement sound level compared to\nthe mixture SMA11. The influence of each texture wavelength on the different frequency bands of the\ntire/pavement noise spectrum was studied, however, this relation is not a simple matter. This paper\nalso presents low-noise pavement labeling methodology (LNP labelingLA2IC). The mixtures SMA11\nand SMA16 are labeled at 50 and 80 km/h. An acoustic label is a valuable tool for construction\ncompanies and urban planners to use in order to define the best option against noise when pavement\nrehabilitation must be carried out.
