A pavement block with a porous filter is provided to prevent temperature rise of the ground surface by promoting heat circulation between the air and the ground. A pavement block comprises a footpath block(10) in which a filter hole(12) bored from the upper surface(14) to the lower surface, a porous filter(20) which is formed by pressing/injection molding a porous material at the pressure of 100~400kg/cm^2 to have a porosity of 10~40% and the same tapered shape as the filter hole and inserted in the filter hole. The porous material is more than one selected from charcoal, activated charcoal, elvan powder, and ceramic powder. |
