Noise Reduction Performance of Double-Layered Porous Pavement

Cylinder specimens with 100mm diameter were molded in the lab, and absorption coefficient was measured by standing wave tube. Effects between the thicknesses, voids and grades of the up and down layers and the noise reduction performance was analyzed by orthogonal test method. Finally, the noise reduction performances of double-layered pavement was predicted.
