Outline of Final Research Achievements

As a measure to reduce damages in torrential rainfall and urban flood, this study proposes a new permeable pavement, which has inlet surface along the subbase layer. In order to grasp basic hydraulic and mechanical characteristics of this pavement, large scale permeability test for crusher-run material with changing grain size distribution and repeated plate loading test for pavement model under dry and saturated condition were carried out. The permeability of crusher-run material was around 0.1 cm/sec regardless of the grain size distribution. The repeated loading test for pavement model showed that the deflection of pavement surface and the vertical stress on subgrade surface increases due to pavement saturation. These mechanical changes are from degradation of subbase stiffness with saturation.
