In this study, coconut shells were used as aggregate replacement in porous asphalt to observe its effect on sound absorption through Impedance Tube test. For coconut shells aggregate porous asphalt to be used in realistic situations it is essential to ensure its mix integrity, resistance to oxidatio...
