This paper shows frequency characteristic about tire/road noise of five kinds pavement for the purpose of acquiring the data which contributed to a problem in the maintenance repair and applicable examination in the concrete pavement. The measurement was used by a passenger car being driven at a speed of 50km/h and wearing measuring tires. As a result, in the band of 500Hz ～ 2,500Hz, remarkable differences were observed. In the frequency band, tire/road noise of Concrete pavement (consecutive reinforcing rod Co) was most highest, followed by Composite pavement (Change pressure Co + Po), Composite pavement (Normal Co + Po), Asphalt pavement and Normal Co pavement in this order.
