Surface Water Drainage of Roadway Using Concept of Permeable Pavement.

      Аннотация: Over the last few years, cities and suburbs have become larger and densely populated. Earlier road sides of these areas were mostly covered by vegetation and natural surfaces. But now they are replaced by impermeable infrastructures day by day. The absence of these natural surfaces and man-made obstructions have let cities with the challenge of increasing runoff volume during rainy season resulting in serious water logging. Due to this water logging, pavement is facing serious hydraulic pressure specially, during moving of wheel load. This sustained water on pavement has a hazardous impact on flexible pavement resulting in the stripping of bitumen and destroying the bond between aggregate and bitumen.
