摘要
PROBLEM TO BE SOLVED: To provide joint material for paving stones, and a construction method for these in which proper fluidity for evening work in construction can be maintained, in which proper tightening and hardening can be obtained after application of rolling pressure, and in which problems such as outflow by wind and rain, or rattling or breakage by uneven load can be eliminated. ;SOLUTION: In a construction method for paving stones, asphalt is mixed in a total weight ratio of 1-4wt.% with sand of a grain size of a sieve opening of 13.2mm or less to form sand cushion material for the paving stones on a crushed stone layer or asphalt-stabilization-processed layer. The paving stones are then placed on it, and asphalt is mixed in a total weight ratio of 1.5-4.5wt.% with sand of a grain size of a sieve opening of 2.36mm or less to fill joint material comprising an asphalt layer around sand between the paving stones.;COPYRIGHT: (C)1997,JPO
