PAVEMENT STRUCTURE, PAVEMENT METHOD, ROAD WATER PERMEABLE BLOCK AND MANUFACTURING OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pavement structure, a pavement method, a road water permeable block and a manufacturing method thereof, which can prevent a POC layer from deteriorating and a road bed from scouring due to deterioration of the POC layer, improve water permeability by the POC layer and drain rain water retained in an underlayer of the POC layer without requiring a drain ditch.SOLUTION: A pavement structure 10 according to this invention comprises: a road bed 11 formed above a foundation G; a water permeable sheet 12 made of woven or nonwoven fabric laid on the road bed 11; and a porous concrete layer 13 formed on the water permeable sheet 12. Coefficient of permeability of the porous concrete layer 13 is larger than that of the water permeable sheet 12.SELECTED DRAWING: Figure 1
