A method of comparing the performance of pervious concrete cores and compacted cylinders is proposed. This approach uses cylinders subjected to different compaction levels via a Proctor-hammer to create curves that relate the concrete porosity and the desired property. The cores are then compared to the corresponding curve values that match the core's porosity to create adjustment factors for unit weight, permeability, and compressive strength. Cores were comprised of pea gravel, limestone, and recycled aggregate concrete mixtures. Experimental results show that, compared to compacted cylinders of the same porosity, cores have on average the same unit weight, 20% less permeability, and 17% lower compressive strength.
