BLOCK FOR ROADS HAVING IMPROVED ABILITY FOR RAINWATER TO CONTINUOUSLY PERMEATE THROUGH IMPROVED EFFICIENCY FOR DISCHARGING GRANULAR MATERIAL AND POWDERED MATERIAL IMPURITIES, ROAD PAVING STRUCTURE USING SAME, AND METHOD OF CONSTRUCTING SAID STRUCTURE

摘要

The present invention relates to a road block with improved rainwater permeable sustainability through an improvement in discharge efficiency of the contaminants including particulate material and powdery material, a structure of road pavement and its construction methods using the same. The present invention includes a downward wide inclined surface (14) formed on a surface opposite to a flat plate-like rear surface portion (18) to be inclined inward in a direction from a top to a bottom; and engagement fastening portions (11, 12) consisting of a semicircular projection curved surface projected outward, and a semicircular depression curved surface that is connected to the semicircular projection curved surface and is formed to be depressed inside while extending to an end surface of the semicircular projection curved surface on both side surfaces.
