DOI: 10.1080/14680629.2017.1303393
Abstract: Sound absorption coefficients of bituminous mixtures are predicted owing to image analysis. A three-parameter semi-phenomenological model, well adapted to porous road materials, is used. Three geometrical parameters: porosity, resistivity and tortuosity, are estimated. Image analysis… read more here.
