Hydrological Performances on the Modified Permeable Pavement with Precast Hollow Cylinder Micro detention Pond Structure
In this study, a permeable pavement with an on-site subsurface micro-detention pond was developed. Common permeable pavements are typically composed of fine layered particles attributed with low porosity. The permeable pavement with micro-scale detention storage (PPDS) developed in this study is a modified type of interlocking block permeable pavement consisting of a hollow cylinder with a hexagonal cover at the top and bottom of the PPDS. The PPDS was designed with a void volume of 70% and a water storage capacity of 0.19 m³/m². A rainfall simulator was used to perform the tests on the profile of the hydrological pavement such as the storage capacity, detention period, permeability rates and infiltration performance over various storm events. The PPDS showed its ability to detain first flushes of rainfall within a 15-minutes period for a 100 year return period. Meanwhile, the permeability rate of the PPDS was subjected to the infiltration capacity of the subgrade soil following a linear relationship between the flow depths over time. The testing performances indicated that the PPDS has met the basic hydrological design considerations, as those in the typical permeable pavement, from the perspective of permeability rates, infiltration capacity, storage and detention capability.
