Title:
PAVING BLOCK AND ITS LAYING METHOD
Document Type and Number:
WIPO Patent Application WO/2000/061868
Kind Code:
A1
Abstract:
A paving block having a prismatic body parallel grooves are formed in the whole top of the body. The pitch of the adjacent grooves and the distance between the groove and the joint are substantially equal to one another. One of the sides of the block body has a projection for fitting the adjacent block bodies to each other, and the other has a groove into which the projection of the adjacent block body is fitted. When a pavement is constructed by such paving blocks, the wheels of wheelchairs and baby carriages hardly rattle and vibrate at the joints between the blocks and the rattling and vibration are hardly transmitted to the bodies of the wheelchairs and baby carriages while they move on the pavement. When the blocks are laid, the adjacent blocks are jointed and the blocks are flush with one another. Therefore, even if a heavy load is exerted on one block, the load is distributed to the adjacent blocks, causing no unevenness and step due to settlement and slant.
