Abstract
As for the rubber elastic pavement, a high noise reduction effect is provided than conventional porous pavement, and what can largely reduce the tire/road noise at the time of a low speed run and the shopping cart noise is found. It is thought that noise reduction effect of rubber elastic pavement is affected by noise absorption characteristics, thickness, the elasticity, impulsive relaxation characteristics of a pavement. In this study, it was examined the influence that the static spring constant as the elastic softness and the impulsive acceleration as impulsive relaxation characteristics of rubber elastic pavement gave to the vehicle tire/road noise and the shopping cart noise. As a results, it was found that the static spring constant and the impulsive acceleration of rubber elastic pavement were related to influence on reduction characteristics of the vehicle tire/road noise and the shopping cart noise.
