  1. Effects of Pervious Pavement on Speedway by Zaid Admani Steven Zhao Brent Crawford

  2. OBJECTIVE • To determine the benefits of pervious pavement and how it will enhance sustainability and reduce storm water runoff on campus.

  3. Project Scope • Describe the study area • Evaluate the current flow condition of the study area • Determine how pervious pavement will reduce storm water runoff and pondingand improve water quality • Quantify the impacts of pervious pavement • Decide on the most optimal design for our study area

  4. Study Area 1000 ft2 • Loose gravel and sand • Ponding after rainfall • No filter medium SPEEDWAY

  5. LiDAR

  6. Operation • High foot traffic area • Used for bike racks • Slight ponding • mudding • Storm water runoff into street

  7. Evaluation • Current ponding causes mudding • Stagnated water after rainfall • No sufficient filtering of water

  8. Ponding from 15 min Rainfall

  9. Ponding from 60 min Rainfall

  10. Potential Solutions • Bio retention • Upgrade soil or plant vegetation • Pervious pavement

  11. Pervious Pavement Reduces: • Peak flow of storm water up to 50 % • Ponding Improves: • Water quality • Curb appeal

  12. Reduction of Peak Flow

  13. Cross Section

  14. Side View

  15. Water Quality Treatment • Reduction of hydrocarbons( motor oil, grease, and gasoline) • PAH’s • Metals (Pb, Cu, Zn, Cd, Cr) • Sediment • Nutrients • Chloride • Bacteria

  16. Conclusion • Mudding and ponding on Speedway from rainfall events • Installation of pervious pavement • Reduction in peak flow by 50% • Elimination of ponding • Improved water quality • Adds utility(ex. more bike racks) • Future Plans • Determine layout and dimensions of pervious pavement • Determine aggregate size for open graded base
