PROBLEM TO BE SOLVED: To provide a side ditch structure of drainage pavement with extremely high drainage capacity which has enough load bearing capacity even when car tire passes over on the lid, and does not require formation of a cutout section for passing water in the lid. SOLUTION: A vertically rugged member 10 with projections and recessions is integrally molded to an apron portion 4 of an L-shaped block 1 with water- impermeable concrete 7, and at least a top of projecting part 11 of a supporting stepped section 8 of the drainage ditch 6 is being exposed. The permeable pavement material 13 is laid on the vertically rugged member 10, and a driveway side edge of the lid 16 is supported on the projecting part 11 of the exposed water-impermeable concrete 7.
