Abstract

Pavements that produce less noise at the tire/pavement interface represent an important strategic solution necessary to minimize traffic acoustic impact. Several international studies showed encouraging results in traffic noise reduction using Asphalt Rubber (AR) mixtures. The Authors present results of an Italian experience that investigates the acoustic properties of AR mixtures, paved on existing roads as wearing course, by means of in situ noise measurements carried out at different stages. These materials were studied through laboratory tests for sound absorption evaluation. Results also evaluate the properties of AR mixtures in limiting traffic noise comparing them with other typical asphalt concretes.
