Abstract :
perviousconcrete is a special kind of concrete which has a high degree of porosity and one of its major applications is in the roadway pavements. Todays, due to transportation importance, using of new materials in land, sea, airand railway transportation infrastructures is among hot research topic. Pervious concrete is one kindof the rigid pavement which has great advantages include; high permeability, proper hydraulic conduction, surface water filtration and to the underground water sourcesinjection. Despite having many advantages, its low compressive strength is one of its disadvantageswhich indicate demands for deeperstudies to increase the compressive strength of this type of concrete. In this research, a series of experimentaltestsis done on typical aggregate samples with different material and graduation, in first step their physical and specious properties was examined and then after preparation of different mix designs for making perviousconcrete sample, properties of obtained concrete samples like: permeability, porosity, and compressive strength were investigated, after that, conducting the tests on various specimens, the results were analyzed. Finally, based on the results and analyses of the conducted tests, the optimum mix designs were introduced based on their application.
