FRJ is designed to improve the disadvantage of connection leakage in existing expansion joint, replaceable integrated rubber sheet reduces maintenance costs innovatively.






- For easy replacement of the rubber sheet, a wire is inserted.
- Expansion joints in road shoulder of the upper plate is detachable.








Frequent breakages of drainage rubber sheet and leakage of the connection had caused frequent maintenance. FRJ has been developed to reduce the maintenance costs and for easy construction.




- Frequent breakage caused by debris deposition in rubber sheets.
- Excessive repair costs.(replacing whole product)
- Causing traffic congestion during maintenance.
- Corrosions in bearing and expansion joint caused by leakage in connection.












- FRJ using aluminum that have excellent corrosion resistance expects excellent durability and long life expectancy.

- Detachable expansion joints in road shoulder of the upper plate make easy maintenance.

- It is possible to reduce the maintenance costs, since only the rubber sheet can be replaced in part.

- Free-setting device is developed to easily adjust in the field and it improves the road flatness.
