In the rainy season, many cases of roads being submerged in water because of a lack of drainage capacity and low water absorption by the subgrade. This study utilizes porous pavement as an interlocking pavement to increase water absorption to the drainage layer and subgrade. Porous concrete is made from cement mixture : coarse aggregate = 1:6 with w/c ratio 0,4. The results showed the value of specific gravity, water absorption, compressive strength, and Na 2 SO 4 resistance respectively 1.703 gr/cm3, 2.57%, 10.8 MPa, and 0.79%. To see the level of serviceability, no fine interlocking pavement is arranged above the drainage layer and the levelling layer, and then a trajectory and inundation test is performed. The result of inundation and track tests shows that the construction can pass water to subgrade without inundation and can withstand the wheel loader that is equivalent to 13000 kg so that it can be used for sidewalks, park lanes, and pavement with a maximum axle load of 8 tons.
