行なわなければならないという問題があった。Conventionally, steel finger joints, rubber joints, etc. have been installed at road joints, but the rough joint members with loose joint gaps are exposed on the road surface. There is a boundary between the fixed concrete part and the asphalt pavement, which are made of different materials, and a step is created at the boundary due to the difference in the degree of wear of the road surface due to enemy debris, which impedes vehicle driving performance and causes strong vibrations at the road joint. , low-frequency vibrations and noise are generated, and in repair work, it takes a lot of time to remove the concrete parts and anchor bars when replacing damaged joint members, so it takes a lot of time to repair, and traffic is closed during that time. There was a problem that it had to be done.
