Porous concrete has been widely used for many purposes in this couple of days. In reality, it might be difficult to create an ideal uniform graded porous concrete mixture proportion with the field gradation circumstances. The aim of this study was to find a porous concrete mix-design proportion that could adjust field gradation and meet Specifications requirements by utilizing continuous graded aggregate. Compressive strength and vertical permeability produced by porous concrete using continuous graded aggregate stayed above the minimum limit for base layer required by Specifications. Continuous graded porous concrete from mix-design variation II produced higher compressive strength, but lower void content and vertical permeability compared to mix design variation I at the age of 28-days. It was found that continuous graded porous concrete from both mix-design variations had an optimum basic parameters in specific value as well. Porous concrete that adjust the field gradation gave a better basic property criteria compared to ideal gradation. The relationship between void content and vertical permeability from continuous graded porous concrete had a similar behavior with uniform graded porous concrete. Overall, the use of continuous graded porous concrete would be very helpful in Indonesia because it can adjust the gradation on the field.
