Title:
METHOD OF INJECTING MATERIAL INTO LOWER SURFACE OF PAVEMENT SURFACE LAYER MATERIAL BLOCK
Document Type and Number:
Japanese Patent JP2021032067
Kind Code:
A
Abstract:
To allow sufficient penetration of a CA mortar (sol solution state) or fluid member into the voids of a crushed stone or aggregate layer of a spacer installed on the lower surface of a block.SOLUTION: A hole (expression 3) having a diameter of 8 mm or more and 150 mm or less from a point 400 mm or more away from the surface edge of a block (expression 1) is bored toward the bottom. CA mortar can be injected into the lower surface of the block having a surface size of any size by injecting the CA mortar through the hole (expression 3). After injecting the CA mortar, the holes may be visibly noticeable and spoil the landscape. To compensate for a decrease in the strength of the block and to give an accent, a material of the same quality as the surface layer material or a material being a different material is injected into the hole (expression 3) after injecting the CA mortar.SELECTED DRAWING: Figure 1
