Abstract
In Japan, there have been growing demands for the protection and improvement of roadside living environment. One of the environmental problems is traffic noises. Porous asphalt has such functions as permeability and tire noise reduction, therefore has rapidly spread due to contribution to safe driving and improvement of environment around roads. Its annual achievement area in Japan estimated at more than 30 million square meters. Furthermore some types of low noise pavements such as porous cement concrete, thin layer overlay, SMA and porous elastic road surface are developed in Japan. This paper provides an overview of Japanese developments and experiences about construction and performance of low noise pavements.
