Document Type and Number:
Japanese Patent JP7194389
Kind Code:
B2
Abstract:
To provide a block, a method for manufacturing the block, and a construction method using the block capable of having weed control ability at a joint on a boundary line with a pavement surface of a road.SOLUTION: A block 11 is installed on a road and has a first groove formed along a boundary line at a portion in contact with a boundary with a paved surface A of the road. Inside the first groove, a part of a chevron 1600 is formed in a cross section orthogonal to the boundary line direction. A cut groove formed of the first groove and a second groove formed on a pavement portion of the road and extending along the boundary line may be formed so that a cross section orthogonal to the boundary line direction is W-shaped.SELECTED DRAWING: Figure 3-2
