Abstract

To find an alternative method to replace the reverberation chamber method and the standing wave tube method in evaluating noise reduction effect, the damping characteristics of several low-noise asphalt pavements were studied by uniaxial unconfined dynamic repeated loading test. The correlation between damping and sound absorption coefficient was established, and the influencing factors of damping characteristics were investigated. The results revealed a good correlation between the damping and the sound absorption coefficient of bituminous mixtures. As the damping value increased, the sound absorption coefficient also increased. Bituminous mixtures exhibited preferable noise reduction performance. The noise reduction effect of bituminous mixtures can be evaluated indirectly by damping. The major factors influencing damping were the static and dynamic moduli of bituminous mixture, as well as the viscosity and porosity of bitumen. The smaller the static and dynamic moduli of bituminous mixture, the higher the viscosity and porosity of bitumen, the greater the damping value, and the more prominent the noise reduction effect.
