Latest developments in Japan regarding improved porous elastic road surface

The Public Works Research Institute (PWRI) has, since 1993, been developing a new low noise pavement named "Porous Elastic Road Surface" (PERS). This new pavement has a porous structure composed of granulate rubber made from old used tires as its aggregate and urethane resin as its binder. The author estimates that the potential noise reduction levels in Leq exceed 10 dB(A). More than 90 per cent of highways in urban areas would meet the standard if this noise reduction level were achieved. This paper summarizes the results of recent research done to further improve the noise reduction levels of PERS and the first test construction using PERS in Japan.
