Asphalt　rubber　pavement　can　improve　using　property　of　road,　as　well　as　reduce　traffic　noise.　To　study　the　relationship　between　traffic　noise　reduction　and　component　of　asphalt　rubber,　based　on　the　theories　of　what　creates　the　tire/pavement　noise,　this　paper　analyzes　traffic　noise　reduction　properties　of　asphalt　rubber　pavement,　and　investigates　elements　in　relation　to　traffic　noise　reduction　of　asphalt　rubber　pavement.　The　results　indicate　that　the　three　important　elements　which　influence　traffic　noise　reduction　of　asphalt　rubber　pavement　are　AC　content,　aggregate　grades　and　ratio　of　air　voids.
