説明

The reduction of the road traffic noise by the construction of the porous elasticity pavement was estimated theoretically. Then, the improvement of rate for meeting environmental quality standard of the road traffic noise for the Kitakyushu City was examined. The results are shown in the following. 1) The decrease of the average power level of small-sized motor vehicle and large-sized one in changing the usual pavement for the porous elasticity pavement is large. 2) On the other hand, the change of sound spectrum does not contribute much to the noise reduction. That is, the noise reduction in installing barrier on the porous elasticity pavement is equivalent to it on the usual pavement. 3) The noise reduction by the construction of the porous elasticity pavement is large. Most site of arterial road in the Kitakyushu City suits the environmental standard of road traffic noise. 4) However, the noise reduction decreases in proportion to commercial vehicles ratio. It is necessary to consider the countermeasure to the large-sized motor vehicles for the case in which there are many large-sized ones.
