There are basically several types of expansion joints that are commonly used in bridge construction structures. However, in broad terms, the types of expansion joints are divided into two, namely open joints and closed joints. This division is as stated in a handbook released by the Florida Department of Transportation.
The distribution of open and closed expansion joints is based on the state of the joint itself. An open expansion joint indicates that there is a gap between the joints that is visible to the naked eye. Meanwhile, closed expansion joints tend to be less visible because the gaps are covered by certain materials, both rubber seals and other fillers.
