PAVING STONE SAND CUSHION MATERIAL, JOINT FILLER AND EXECUTION METHOD OF PAVING STONE MAKING USE THEREOF

PROBLEM TO BE SOLVED: To develop a paving stone joint filler and an execution method thereof capable of maintaining proper flowability for carrying out leveling work in the case of execution, obtaining proper compaction after the rolling and solving an outflow caused by wind and rain, a shakiness resulting from eccentric load and an abuse of damage or the like. SOLUTION: The execution method of the paving stone is so constituted that asphalt is mixed within a range of a total weight ratio 1 to 4 wt.% by making sand having grain size of the as large as sieve 13.2 mm mesh or less as the object to lay a paving stone sand cushion material forming an asphalt layer around the sand on a crushed stone layer or on a layer applying asphalt stabilization thereon to lay the paving stone thereon and that a void of the paving stone is filled with the paving stone joint filler forming the asphalt layer around the sand by mixing asphalt within a range of a total weight ratio 1.5 to 4.5 wt.% by making sand having grain size as large as sieve mesh 2.36 mm or less as the object.
