Investigation of microstructure characteristics of porous asphalt with relevance to acoustic pavement performance
Both spatial characteristics and the structure of air voids have certain impacts on the acoustic properties of porous asphalt, with regard to sound absorption behavior. Aside from global parameters of the microstructure, like porosity, certain geometrical characteristics of air voids also have an ef...
