Paper, 2002Beskrivning: 10 sÄmnen: Bibl.nr: VTI 2002.0071Location: Abstrakt: Porous asphalt pavement is widely used on expressways in Japan. This type of pavement offers great performance in driving safety during the rain and the reduction of traffic noise. It is also said, that the porous structure of porous asphalt pavement gives winter road surface characteristics differ from those of conventional dense-asphalt pavement. In order to quantitatively evaluate such characteristics, Japan Highway Public Corporation (hereafter called JH) conducted on-site study. As a result, it was found that there is no significant difference between porous asphalt and dense-asphalt pavement in terms of road surface characteristics, hence no major modification is required to the existing road maintenance method for winter. It was also found that porous asphalt pavement is effective in preventing freezing of road surface. This study focuses on winter road characteristics, i.e. road surface temperature, road surface conditions, effect of anti-icing chemicals and skid resistance.| Aktuellt bibliotek | Status | |
