Application of permeable pavement in urban roads as an alternative flooding reduction in Jakarta.

Over decades, urban roads in Jakarta have been suffering from flooding due to excessive surface runoff. A majority of existing urban road pavement installation in Jakarta has been utilizing the conventional pavement type. A typical conventional pavement is ineffective in reducing the surface runoff volume, particularly during high precipitation events. All stormwater has to flow onto the drainage with extreme discharge. As a consequence, the urban roads are full of puddles of various heights and lengths of time. To reflect on this issue, the authors conducted a review paper, to sum up, the extensive but dispersed literature on commonly permeable pavements. This study reviewed porous asphalt, pervious concrete, and interlocking concrete pavers. In addition, four crucial points are highlighted as consideration: (1) the structural capability, (2) permeability, (3) water quality and (4) economic risk. This research review concluded that permeable pavement is more effective in reducing flooding compared to conventional pavement. Among those three pavement types, porous asphalt pavement is the most possible to be implemented for urban roads in Jakarta, especially for light traffic. Since this pavement meets the Indonesian national standard requirements for structural capability and has less economic risk. [ABSTRACT FROM AUTHOR]
