The aim of the investigation is to assess the features of the utilization of a geo polymer binder for producing permeable geopolymer concrete. Materials used for producing pervious geopolymer concrete are fly ash, ground granulated blast furnace slag with the proportion of 60:40, sodium silicate solution, sodium hydroxide and coarse aggregate. The strength, functional characteristics and its relationship of the geo polymer pervious concrete were investigated. Compressive strength of geo polymer permeable concrete has enhanced along with the rise in density of Pervious geo polymer concrete. Permeability and voids exhibit a decreasing pattern with the increase in molarity and alkali binder ratio. Based on the strength attainment in the previous geo polymer concrete, it has used as a sub - base and base course of a flexible pavement layers.
