Empirical Rolling Noise Prediction Models Based on Pavement Surface Characteristics

Abstract

ABSTRACT Tyre/road noise is a complex phenomenon which is function of tyre, surface properties and speed. This study aims to define a rolling noise prediction model for a reference tyre, as a function of speed, on dense asphalt surfaces with medium-low macrotexture levels. The model was defined by relating texture levels of pavement profiles and rolling noise levels recorded at different speeds. The study also defines an extension of the model valuable for semi-porous surfaces, as a function of only surface characteristics. Both of the models serve as a support tool for mix design of low noise asphalt pavement surfaces. KEYWORDS: Rolling NoiseTexture LevelsAcoustic AbsorptionModelingPavement Profile
