Zusammenfassung:In this paper, the authors mainly describe a method inferring void structure and the functions of the drainage asphalt pavement, analyzing sound absorption spectrum using the standing wave method. The void content and the tortuosity are estimated from the peak sound absorption coefficient and the peak sound absorption frequency. In addition, the permeability is presumed from the shape of sound absorption spectrum.
