The cotter-joint method is a method of joining precast slabs with cotter joints, which are mechanical joints, and was developed with the objective of shortening the process, saving labor, improving quality, and improving maintainability.
In this report, we apply this method to the replacement work of the slab of the actual bridge and report the result of confirming the construction accuracy.
