  • Abstract:
  • Pervious concrete is one of the best emerging technologies especially used for the surface runoff and to keep the pavement dry for riding conditions. The key concept is the presence of inter connecting voids through which water escapes out leaving the surface dry in contrast to the conventional rigid pavements where we use a mixture of cement ,fine aggregate and coarse aggregate which makes a water tight impervious concrete surface. The absence of the fine aggregate creates a lot of space for the water to infiltrate to the bottom layers from where it will be drained out .By many experiments the infiltration rate comes out to the value of approximately 312 inches / hour. The greatest application areas of these pervious concrete are the airport pavements (recently), footpaths and parkings lots. Pervious concrete is formed by a mixture of cement and coarse aggregate with minimum or no fines or zero fine aggregates. Lots of experimental analysis have been done on this new emerging concept to draw conclusions like use of different water quantities to find infiltration rates ,replacement of cement with slag,TiO2,fly ash etc to find the strength parameters like compressive strengths ,split tensile strengths ,permeability etc, infiltration rate will be increased with provision of beneficial slope in the pavement like 5 % and so on .
