Pervious concrete,Porous surface, Rain water runoff, No-fines concrete, Permeable pavement
In modern day infrastructure, use of impervious surfaces on pavements to rapidly collect and transport rain water runoff is very important. Due to this storm water reachesthe water bodies rapidly, in bigger volume and carries more contaminants than natural conditions. Permeable pavement on parking lots, sidewalks, and driveways provides asolution to this problem. One such material that can be used to produce porous surfaces ispervious concrete. Even though no-fines concrete mix has been used for many years, thereare still many unresolved issues related to its structural performance and issues withreduced filtration capacity over time especially when exposed to real conditions. Thispaper presents a study describing a project pervious concrete system. The details of the construction technique including details of the material used are described in this paper.On-going tests to monitor the performance of this test slab are also described.
