Several studies demonstrated that road roughness plays an important role in the generation of tire vibration and radiated noise. One of these studies theoretically predicted the relationship between road roughness parameters and tire vibration and radiated noise. In this paper, the relationship is discussed in order to propose a method of designing a quiet pavement. The prediction is examined by two sets of measurements on actual road surfaces. First, the tire tread vibration was measured on three types of road surface. Second, tire/road noise was measured on 13 samples of road surface. The results show a tendency that supports the prediction which indicates that the spacing and height unevenness of pavement asperities should be small to abate tire vibration and radiated noise
