OGFC can reduce traffic noise which has very high air-void contents to absorb tire-pavement noise. This paper proposes maximum aggregate size and aggregate gradation of OGFC with the objective void of 20%. Performance of modified asphalt and best asphalt-aggregate ratio are also proposed with four kinds of modifiers, including SBS, rubber, EVA and PVC. The absorption coefficients of the four kinds of OGFC and the dense-graded Marshall specimens were tested with standing wave tube. Then their sound absorption performances were compared.
