The present work attempts to investigate the applicability of using recycled aggregate for the development of pervious concrete and for mitigating liquefaction and reliquefaction effects. The dynamic behaviour of developed recycled aggregate-based pervious concrete pile is compared with natural aggregate-based pervious concrete pile. The study attempts to explore the inherent material properties of pervious concrete keeping permeability equivalent to conventional stone columns but with improved mechanical characteristics with enhanced pore water pressure ratio reduction and soil displacement reduction efficiency under repeated incremental acceleration loading conditions. For testing, 1g shaking table tests were performed with 01 g, 02 g, 03 g and 04 g acceleration loading with 5 Hz frequency. The outcomes obtained from this experimental study infer that recycled aggregate-based pervious concrete pile exhibits a superior performance compared with natural aggregate-based pervious concrete pile. Overall, the use of recycled aggregate found sustainable approach for developing pervious concrete pile and found effective ground improvement application against liquefaction and reliquefaction hazards.
